/* The Fragmenter is a bit tricky, because there are 5 sizes in play:
* max size -- the maximum transfer size possible
* orig size -- the original pre-fragmenter size
* frag size -- the modified post-fragmenter size
* min size -- the threshold below which frag=orig
* beat size -- the amount transfered on any given beat
*
* The relationships are as follows:
* max >= orig >= frag
* max > min >= beat
* It IS possible that orig <= min (then frag=orig; ie: no fragmentation)
*
* The fragment# (sent via TL.source) is measured in multiples of min size.
* Meanwhile, to track the progress, counters measure in multiples of beat size.
*
* Here is an example of a bus with max=256, min=8, beat=4 and a device supporting 16.

s = sigWidth
c_i = newBit
Division:
width of a is (s+2)
Normal
------
(qi + ci * 2^(-i))*b <= a
q0 = 0
r0 = a
q(i+1) = qi + ci*2^(-i)
ri = a - qi*b
r(i+1) = a - q(i+1)*b
= a - qi*b - ci*2^(-i)*b
r(i+1) = ri - ci*2^(-i)*b
ci = ri >= 2^(-i)*b
summary_i = ri != 0
i = 0 to s+1
(s+1)th bit plus summary_(i+1) gives enough information for rounding
If (a < b), then we need to calculate (s+2)th bit and summary_(i+1)
because we need s bits ignoring the leading zero. (This is skipCycle2
part of Hauser's code.)
Hauser
------
sig_i = qi
rem_i = 2^(i-2)*ri
cycle_i = s+3-i
sig_0 = 0
rem_0 = a/4
cycle_0 = s+3
bit_0 = 2^0 (= 2^(s+1), since we represent a, b and q with (s+2) bits)
sig(i+1) = sig(i) + ci*bit_i
rem(i+1) = 2rem_i - ci*b/2
ci = 2rem_i >= b/2
bit_i = 2^-i (=2^(cycle_i-2), since we represent a, b and q with (s+2) bits)
cycle(i+1) = cycle_i-1
summary_1 = a <> b
summary(i+1) = if ci then 2rem_i-b/2 <> 0 else summary_i, i <> 0
Proof:
2^i*r(i+1) = 2^i*ri - ci*b. Qed
ci = 2^i*ri >= b. Qed
summary(i+1) = if ci then rem(i+1) else summary_i, i <> 0
Now, note that all of ck's cannot be 0, since that means
a is 0. So when you traverse through a chain of 0 ck's,
from the end,
eventually, you reach a non-zero cj. That is exactly the
value of ri as the reminder remains the same. When all ck's
are 0 except c0 (which must be 1) then summary_1 is set
correctly according
to r1 = a-b != 0. So summary(i+1) is always set correctly
according to r(i+1)
Square root:
width of a is (s+1)
Normal
------
(xi + ci*2^(-i))^2 <= a
xi^2 + ci*2^(-i)*(2xi+ci*2^(-i)) <= a
x0 = 0
x(i+1) = xi + ci*2^(-i)
ri = a - xi^2
r(i+1) = a - x(i+1)^2
= a - (xi^2 + ci*2^(-i)*(2xi+ci*2^(-i)))
= ri - ci*2^(-i)*(2xi+ci*2^(-i))
= ri - ci*2^(-i)*(2xi+2^(-i)) // ci is always 0 or 1
ci = ri >= 2^(-i)*(2xi + 2^(-i))
summary_i = ri != 0
i = 0 to s+1
For odd expression, do 2 steps initially.
(s+1)th bit plus summary_(i+1) gives enough information for rounding.
Hauser
------
sig_i = xi
rem_i = ri*2^(i-1)
cycle_i = s+2-i
bit_i = 2^(-i) (= 2^(s-i) = 2^(cycle_i-2) in terms of bit representation)
sig_0 = 0
rem_0 = a/2
cycle_0 = s+2
bit_0 = 1 (= 2^s in terms of bit representation)
sig(i+1) = sig_i + ci * bit_i
rem(i+1) = 2rem_i - ci*(2sig_i + bit_i)
ci = 2*sig_i + bit_i <= 2*rem_i
bit_i = 2^(cycle_i-2) (in terms of bit representation)
cycle(i+1) = cycle_i-1
summary_1 = a - (2^s) (in terms of bit representation)
summary(i+1) = if ci then rem(i+1) <> 0 else summary_i, i <> 0
Proof:
ci = 2*sig_i + bit_i <= 2*rem_i
ci = 2xi + 2^(-i) <= ri*2^i. Qed
sig(i+1) = sig_i + ci * bit_i
x(i+1) = xi + ci*2^(-i). Qed
rem(i+1) = 2rem_i - ci*(2sig_i + bit_i)
r(i+1)*2^i = ri*2^i - ci*(2xi + 2^(-i))
r(i+1) = ri - ci*2^(-i)*(2xi + 2^(-i)). Qed
Same argument as before for summary.
------------------------------
Note that all registers are updated normally until cycle == 2.
At cycle == 2, rem is not updated, but all other registers are updated normally.
But, cycle == 1 does not read rem to calculate anything (note that final summary
is calculated using the values at cycle = 2).

/** These wrap behavioral
* shift and next registers into specific modules to allow for
* backend flows to replace or constrain
* them properly when used for CDC synchronization,
* rather than buffering.
*
*
* These are built up of *ResetSynchronizerPrimitiveShiftReg,
* intended to be replaced by the integrator's metastable flops chains or replaced
* at this level if they have a multi-bit wide synchronizer primitive.
* The different types vary in their reset behavior:
* NonSyncResetSynchronizerShiftReg -- Register array which does not have a reset pin
* AsyncResetSynchronizerShiftReg -- Asynchronously reset register array, constructed from W instantiations of D deep
* 1-bit-wide shift registers.
* SyncResetSynchronizerShiftReg -- Synchronously reset register array, constructed similarly to AsyncResetSynchronizerShiftReg
*
* [Inferred]ResetSynchronizerShiftReg -- TBD reset type by chisel3 reset inference.
*
* ClockCrossingReg -- Not made up of SynchronizerPrimitiveShiftReg. This is for single-deep flops which cross
* Clock Domains.

/* The Fragmenter is a bit tricky, because there are 5 sizes in play:
* max size -- the maximum transfer size possible
* orig size -- the original pre-fragmenter size
* frag size -- the modified post-fragmenter size
* min size -- the threshold below which frag=orig
* beat size -- the amount transfered on any given beat
*
* The relationships are as follows:
* max >= orig >= frag
* max > min >= beat
* It IS possible that orig <= min (then frag=orig; ie: no fragmentation)
*
* The fragment# (sent via TL.source) is measured in multiples of min size.
* Meanwhile, to track the progress, counters measure in multiples of beat size.
*
* Here is an example of a bus with max=256, min=8, beat=4 and a device supporting 16.
