This block is used to breakout the 256 bit streaming ports to and from the write master.
The information sent through the streaming ports is a bundle of wires and buses so it's
fairly inconvenient to constantly refer to them by their position amungst the 256 lines.
This block also provides a layer of abstraction since the descriptor buffers block has
no clue what format the descriptors are in except that the 'go' bit is written to. This
means that using this block you could move descriptor information around without affecting
the top level dispatcher logic.
1.0 06/29/2009 - First version of this block of wires
1.1 11/15/2012 - Added in an additional 32 bits of address for extended descriptors

This block is used to communicate information back and forth between the SGDMA
and the host. When the response port is not set to streaming then this block
will be used to generate interrupts for the host. The address span of this block
differs depending on whether the enhanced features are enabled. The enhanced
features enables sequence number readback capabilties. The address map is as follows:
Enhanced features off:
Bytes Access Type Description
----- ----------- -----------
0-3 R Status(1)
4-7 R/W Control(2)
8-12 R Descriptor Watermark (write watermark[15:0],read watermark [15:0])
13-15 R Response Watermark
16-31 N/A <Reserved>
Enhanced features on:
Bytes Access Type Description
----- ----------- -----------
0-3 R Status(1)
4-7 R/W Control(2)
8-12 R Descriptor Watermark (write watermark[15:0],read watermark [15:0])
13-15 R Response Watermark
16-20 R Sequence Number (write sequence[15:0],read sequence[15:0])
21-31 N/A <Reserved>
(1) Writing to the interrupt bit of the status register clears the interrupt bit (when applicable)
(2) Writing to the software reset bit will clear the entire register (as well as all the registers for the entire SGDMA)
Status Register:
Bits Description
---- -----------
0 Busy
1 Descriptor Buffer Empty
2 Descriptor Buffer Full
3 Response Buffer Empty
4 Response Buffer Full
5 Stop State
6 Reset State
7 Stopped on Error
8 Stopped on Early Termination
9 IRQ
10-15 <Reserved>
15-31 Done count (JSF: Added 06/13/2011)
Control Register:
Bits Description
---- -----------
0 Stop (will also be set if a stop on error/early termination condition occurs)
1 Software Reset
2 Stop on Error
3 Stop on Early Termination
4 Global Interrupt Enable Mask
5 Stop descriptors (stops the dispatcher from issuing more read/write commands)
6-31 <Reserved>
Author: JCJB
Date: 08/18/2010
1.0 - Initial release
1.1 - Removed delayed reset, added set and hold sw_reset
1.2 - Updated the sw_reset register to be set when control[1] is set instead of one cycle after.
This will prevent the read or write masters from starting back up when reset while in the stop state.
1.3 - Added the stop dispatcher bit (5) to the control register

This block is used to communicate information back and forth between the SGDMA
and the host. When the response port is not set to streaming then this block
will be used to generate interrupts for the host. The address span of this block
differs depending on whether the enhanced features are enabled. The enhanced
features enables sequence number readback capabilties. The address map is as follows:
Enhanced features off:
Bytes Access Type Description
----- ----------- -----------
0-3 R Status(1)
4-7 R/W Control(2)
8-12 R Descriptor Watermark (write watermark[15:0],read watermark [15:0])
13-15 R Response Watermark
16-31 N/A <Reserved>
Enhanced features on:
Bytes Access Type Description
----- ----------- -----------
0-3 R Status(1)
4-7 R/W Control(2)
8-12 R Descriptor Watermark (write watermark[15:0],read watermark [15:0])
13-15 R Response Watermark
16-20 R Sequence Number (write sequence[15:0],read sequence[15:0])
21-31 N/A <Reserved>
(1) Writing to the interrupt bit of the status register clears the interrupt bit (when applicable)
(2) Writing to the software reset bit will clear the entire register (as well as all the registers for the entire SGDMA)
Status Register:
Bits Description
---- -----------
0 Busy
1 Descriptor Buffer Empty
2 Descriptor Buffer Full
3 Response Buffer Empty
4 Response Buffer Full
5 Stop State
6 Reset State
7 Stopped on Error
8 Stopped on Early Termination
9 IRQ
10-15 <Reserved>
15-31 Done count (JSF: Added 06/13/2011)
Control Register:
Bits Description
---- -----------
0 Stop (will also be set if a stop on error/early termination condition occurs)
1 Software Reset
2 Stop on Error
3 Stop on Early Termination
4 Global Interrupt Enable Mask
5 Stop descriptors (stops the dispatcher from issuing more read/write commands)
6-31 <Reserved>
Author: JCJB
Date: 08/18/2010
1.0 - Initial release
1.1 - Removed delayed reset, added set and hold sw_reset
1.2 - Updated the sw_reset register to be set when control[1] is set instead of one cycle after.
This will prevent the read or write masters from starting back up when reset while in the stop state.
1.3 - Added the stop dispatcher bit (5) to the control register

Version 2.0
This logic recieves registers the byte address of the master when 'start'
is asserted. This block then barrelshifts the write data based on the byte
address to make sure that the input data (from the FIFO) is reformatted to
line up with memory properly.
The only throttling mechanism in this block is the FIFO not empty signal as
well as waitreqeust from the fabric.
Revision History:
1.0 Initial version
2.0 Removed 'bytes_to_next_boundary' and using the address to determine how
much out of alignment the master begins.

This FIFO module behaves similar to scfifo in legacy mode. It has an
output latency of 1 or 2 clock cycles and does not support look ahead
mode. Unlike scfifo this FIFO allows you to write to any of the byte
lanes before committing the word. This allows you to write the full
word in multiple clock cycles and then you assert the "push" signal to
commit the data. To read data out of the FIFO assert "pop" and wait
1 or 2 clock cycles for valid data to arrive.
Version 1.1
1.0 - Uses 'altsyncram' which will not be optimized away if the
FIFO inputs are grounded. This will need to be replaced
with inferred memory once Quartus II supports inferred
with byte enables (currently it instantiates multiple
seperate memories.
1.1 - Seperated the asynchronous reset into seperate async. and sync.

(** * Extraction: Extracting ML from Coq *)
(* $Date: 2013-01-16 22:29:57 -0500 (Wed, 16 Jan 2013) $ *)
(** * Basic Extraction *)
(** In its simplest form, program extraction from Coq is completely straightforward. *)
(** First we say what language we want to extract into. Options are OCaml (the
most mature), Haskell (which mostly works), and Scheme (a bit out
of date). *)
Extraction Language Ocaml.
(** Now we load up the Coq environment with some definitions, either
directly or by importing them from other modules. *)
Require Import SfLib.
Require Import ImpCEvalFun.
(** Finally, we tell Coq the name of a definition to extract and the
name of a file to put the extracted code into. *)
Extraction "imp1.ml" ceval_step.
(** When Coq processes this command, it generates a file [imp1.ml]
containing an extracted version of [ceval_step], together with
everything that it recursively depends on. Have a look at this
file now. *)
(* ############################################################## *)
(** * Controlling Extraction of Specific Types *)
(** We can tell Coq to extract certain [Inductive] definitions to
specific OCaml types. For each one, we must say
- how the Coq type itself should be represented in OCaml, and
- how each constructor should be translated. *)
Extract Inductive bool => "bool" [ "true" "false" ].
(** Also, for non-enumeration types (where the constructors take
arguments), we give an OCaml expression that can be used as a
"recursor" over elements of the type. (Think Church numerals.) *)
Extract Inductive nat => "int"
[ "0" "(fun x -> x + 1)" ]
"(fun zero succ n ->
if n=0 then zero () else succ (n-1))".
(** We can also extract defined constants to specific OCaml terms or
operators. *)
Extract Constant plus => "( + )".
Extract Constant mult => "( * )".
Extract Constant beq_nat => "( = )".
(** Important: It is entirely _your responsibility_ to make sure that
the translations you're proving make sense. For example, it might
be tempting to include this one
Extract Constant minus => "( - )".
but doing so could lead to serious confusion! (Why?)
*)
Extraction "imp2.ml" ceval_step.
(** Have a look at the file [imp2.ml]. Notice how the fundamental
definitions have changed from [imp1.ml]. *)
(* ############################################################## *)
(** * A Complete Example *)
(** To use our extracted evaluator to run Imp programs, all we need to
add is a tiny driver program that calls the evaluator and somehow
prints out the result.
For simplicity, we'll print results by dumping out the first four
memory locations in the final state.
Also, to make it easier to type in examples, let's extract a
parser from the [ImpParser] Coq module. To do this, we need a few
more declarations to set up the right correspondence between Coq
strings and lists of OCaml characters. *)
Require Import Ascii String.
Extract Inductive ascii => char
[
"(* If this appears, you're using Ascii internals. Please don't *) (fun (b0,b1,b2,b3,b4,b5,b6,b7) -> let f b i = if b then 1 lsl i else 0 in Char.chr (f b0 0 + f b1 1 + f b2 2 + f b3 3 + f b4 4 + f b5 5 + f b6 6 + f b7 7))"
]
"(* If this appears, you're using Ascii internals. Please don't *) (fun f c -> let n = Char.code c in let h i = (n land (1 lsl i)) <> 0 in f (h 0) (h 1) (h 2) (h 3) (h 4) (h 5) (h 6) (h 7))".
Extract Constant zero => "'\000'".
Extract Constant one => "'\001'".
Extract Constant shift =>
"fun b c -> Char.chr (((Char.code c) lsl 1) land 255 + if b then 1 else 0)".
Extract Inlined Constant ascii_dec => "(=)".
(** We also need one more variant of booleans. *)
Extract Inductive sumbool => "bool" ["true" "false"].
(** The extraction is the same as always. *)
Require Import Imp.
Require Import ImpParser.
Extraction "imp.ml" empty_state ceval_step parse.
(** Now let's run our generated Imp evaluator. First, have a look at
[impdriver.ml]. (This was written by hand, not extracted.)
Next, compile the driver together with the extracted code and
execute it, as follows.
<<
ocamlc -w -20 -w -26 -o impdriver imp.mli imp.ml impdriver.ml
./impdriver
>>
(The [-w] flags to [ocamlc] are just there to suppress a few
spurious warnings.) *)
(* ############################################################## *)
(** * Discussion *)
(** Since we've proved that the [ceval_step] function behaves the same
as the [ceval] relation in an appropriate sense, the extracted
program can be viewed as a _certified_ Imp interpreter. (Of
course, the parser is not certified in any interesting sense,
since we didn't prove anything about it.) *)

[impdriver.ml]. (This was written by hand, not extracted.)
Next, compile the driver together with the extracted code and
execute it, as follows.
<<
ocamlc -w -20 -w -26 -o impdriver imp.mli imp.ml impdriver.ml
./impdriver
>>
(The [-w] flags to [ocamlc] are just there to suppress a few
spurious warnings.) *)
(* ############################################################## *)
(** * Discussion *)
(** Since we've proved that the [ceval_step] function behaves the same
as the [ceval] relation in an appropriate sense, the extracted
program can be viewed as a _certified_ Imp interpreter. (Of
course, the parser is not certified in any interesting sense,
since we didn't prove anything about it.) *)

(** * Extraction: Extracting ML from Coq *)
(* $Date: 2013-01-16 22:29:57 -0500 (Wed, 16 Jan 2013) $ *)
(** * Basic Extraction *)
(** In its simplest form, program extraction from Coq is completely straightforward. *)
(** First we say what language we want to extract into. Options are OCaml (the
most mature), Haskell (which mostly works), and Scheme (a bit out
of date). *)
Extraction Language Ocaml.
(** Now we load up the Coq environment with some definitions, either
directly or by importing them from other modules. *)
Require Import SfLib.
Require Import ImpCEvalFun.
(** Finally, we tell Coq the name of a definition to extract and the
name of a file to put the extracted code into. *)
Extraction "imp1.ml" ceval_step.
(** When Coq processes this command, it generates a file [imp1.ml]
containing an extracted version of [ceval_step], together with
everything that it recursively depends on. Have a look at this
file now. *)
(* ############################################################## *)
(** * Controlling Extraction of Specific Types *)
(** We can tell Coq to extract certain [Inductive] definitions to
specific OCaml types. For each one, we must say
- how the Coq type itself should be represented in OCaml, and
- how each constructor should be translated. *)
Extract Inductive bool => "bool" [ "true" "false" ].
(** Also, for non-enumeration types (where the constructors take
arguments), we give an OCaml expression that can be used as a
"recursor" over elements of the type. (Think Church numerals.) *)
Extract Inductive nat => "int"
[ "0" "(fun x -> x + 1)" ]
"(fun zero succ n ->
if n=0 then zero () else succ (n-1))".
(** We can also extract defined constants to specific OCaml terms or
operators. *)
Extract Constant plus => "( + )".
Extract Constant mult => "( * )".
Extract Constant beq_nat => "( = )".
(** Important: It is entirely _your responsibility_ to make sure that
the translations you're proving make sense. For example, it might
be tempting to include this one
Extract Constant minus => "( - )".
but doing so could lead to serious confusion! (Why?)
*)
Extraction "imp2.ml" ceval_step.
(** Have a look at the file [imp2.ml]. Notice how the fundamental
definitions have changed from [imp1.ml]. *)
(* ############################################################## *)
(** * A Complete Example *)
(** To use our extracted evaluator to run Imp programs, all we need to
add is a tiny driver program that calls the evaluator and somehow
prints out the result.
For simplicity, we'll print results by dumping out the first four
memory locations in the final state.
Also, to make it easier to type in examples, let's extract a
parser from the [ImpParser] Coq module. To do this, we need a few
more declarations to set up the right correspondence between Coq
strings and lists of OCaml characters. *)
Require Import Ascii String.
Extract Inductive ascii => char
[
"(* If this appears, you're using Ascii internals. Please don't *) (fun (b0,b1,b2,b3,b4,b5,b6,b7) -> let f b i = if b then 1 lsl i else 0 in Char.chr (f b0 0 + f b1 1 + f b2 2 + f b3 3 + f b4 4 + f b5 5 + f b6 6 + f b7 7))"
]
"(* If this appears, you're using Ascii internals. Please don't *) (fun f c -> let n = Char.code c in let h i = (n land (1 lsl i)) <> 0 in f (h 0) (h 1) (h 2) (h 3) (h 4) (h 5) (h 6) (h 7))".
Extract Constant zero => "'\000'".
Extract Constant one => "'\001'".
Extract Constant shift =>
"fun b c -> Char.chr (((Char.code c) lsl 1) land 255 + if b then 1 else 0)".
Extract Inlined Constant ascii_dec => "(=)".
(** We also need one more variant of booleans. *)
Extract Inductive sumbool => "bool" ["true" "false"].
(** The extraction is the same as always. *)
Require Import Imp.
Require Import ImpParser.
Extraction "imp.ml" empty_state ceval_step parse.
(** Now let's run our generated Imp evaluator. First, have a look at
[impdriver.ml]. (This was written by hand, not extracted.)
Next, compile the driver together with the extracted code and
execute it, as follows.
<<
ocamlc -w -20 -w -26 -o impdriver imp.mli imp.ml impdriver.ml
