Module idma_nd_midend_synth
Synthesis wrapper for the iDMA backend and the nd-midend combined.
Unpacks all the interfaces to simple logic vectors
Parameters
DataWidth: int unsigned
Data width
AddrWidth: int unsigned
Address width
UserWidth: int unsigned
AXI user width
AxiIdWidth: int unsigned
AXI ID width
NumAxInFlight: int unsigned
Number of transaction that can be in-flight concurrently
BufferDepth: int unsigned
The depth of the internal reorder buffer:
-
‘2’: minimal possible configuration
-
‘3’: efficiently handle misaligned transfers (recommended)
TFLenWidth: int unsigned
With of a transfer: max transfer size is 2**TFLenWidth bytes
MemSysDepth: int unsigned
The depth of the memory system the backend is attached to
NumDim: int unsigned
The number of dimensions
RepWidth: int unsigned
The width of the repetition counters of all dimensions
StrideWidth: int unsigned
The supported stride width
CombinedShifter: bit
Should both data shifts be done before the dataflow element?
If this is enabled, then the data inserted into the dataflow element
will no longer be word aligned, but only a single shifter is needed
MaskInvalidData: bit
Mask invalid data on the manager interface
RAWCouplingAvail: bit
Should the R-AW coupling hardware be present? (recommended)
HardwareLegalizer: bit
Should hardware legalization be present? (recommended)
If not, software legalization is required to ensure the transfers are
AXI4-conformal
RejectZeroTransfers: bit
Reject zero-length transfers
ErrorHandling: bit
Should the error handler be present?
