Module idma_reg64_2d
Description: Register-based front-end for iDMA
Parameters
NumRegs: int unsigned
Number of configuration register ports
NumStreams: int unsigned
Number of streams (max 16)
IdCounterWidth: int unsigned
Width of the transfer id (max 32-bit)
StreamWidth: int unsigned
Dependent parameter: Stream Idx
reg_req_t: type
Register_interface request type
reg_rsp_t: type
Register_interface response type
dma_req_t: type
DMA 1d or ND burst request type
cnt_width_t: type
Dependent type for IdCounterWidth
stream_t: type
Dependent type for StreamWidth
MaxNumStreams: int unsigned
Maximum number of streams is set to 16. It can be enlarged, but the register file
needs to be adapted too.
