//
// Description:
// This module manages multi-threaded transactions for one SI-slot.
// The module interface consists of a 1-slave to 1-master address channel, plus a
// (M+1)-master (from M MI-slots plus error handler) to 1-slave response channel.
// The module maintains transaction thread control registers that count the
// number of outstanding transations for each thread and the target MI-slot.
// On the address channel, the module decodes addresses to select among MI-slots
// accessible to the SI-slot where it is instantiated.
// It then qualifies whether each received transaction
// should be propagated as a request to the address channel arbiter.
// Transactions are blocked while there is any outstanding transaction to a
// different slave (MI-slot) for the requested ID thread (for deadlock avoidance).
// On the response channel, the module mulitplexes transfers from each of the
// MI-slots whenever a transfer targets the ID of an active thread,
// arbitrating between MI-slots if multiple threads respond concurrently.

// Description:
// This module is a bank of AXI4-Lite and AXI3 protocol converters for a vectored AXI interface.
// The interface of this module consists of a vectored slave and master interface
// which are each concatenations of upper-level AXI pathways,
// plus various vectored parameters.
// This module instantiates a set of individual protocol converter modules.

// Description:
// This module is a bank of AXI4-Lite and AXI3 protocol converters for a vectored AXI interface.
// The interface of this module consists of a vectored slave and master interface
// which are each concatenations of upper-level AXI pathways,
// plus various vectored parameters.
// This module instantiates a set of individual protocol converter modules.

// Description:
// This module is a bank of AXI4-Lite and AXI3 protocol converters for a vectored AXI interface.
// The interface of this module consists of a vectored slave and master interface
// which are each concatenations of upper-level AXI pathways,
// plus various vectored parameters.
// This module instantiates a set of individual protocol converter modules.

// Description:
// Read data channel module to buffer read data from MC, ignore
// extra data in case of BL8 and send the data to AXI.
// The MC will send out the read data as it is ready and it has to be
// accepted. The read data FIFO in the axi_protocol_converter_v2_1_b2s_r_channel module will buffer
// the data before being sent to AXI. The address channel module will
// send the transaction information for every command that is sent to the
// MC. The transaction information will be buffered in a transaction FIFO.
// Based on the transaction FIFO information data will be ignored in
// BL8 mode and the last signal to the AXI will be asserted.
