Data Fields | |
| Uint32 * | source |
| IDMA channel 1 Source Address. | |
| Uint32 * | destn |
| IDMA channel 1 Destination Address. | |
| Uint16 | count |
| Number of bytes to be transfered. | |
| Uint32 | priority:3 |
| Transfer Priority. | |
| Uint32 | intEnable:1 |
| Boolean Flag to enable/disable CPU interrupt. | |
| Uint32* CSL_IDMA_IDMA1CONFIG::source |
IDMA channel 1 Source Address.
The source address must point to a word-aligned memory location local to GEM. When performing a block fill, all 32 bits of the address specified are considered; While, for block transfers, the 2 LSBs are ignored and the higher order 30 bits are read as the valid Source Address for transfer.
| Uint32* CSL_IDMA_IDMA1CONFIG::destn |
IDMA channel 1 Destination Address.
The destination address must point to a 32 bit word-aligned memory location local to GEM. This address must be local to GEM, either in L1P, L1D, L2 or CFG and also must be different port than the source address to obtain full throughput.
| Uint16 CSL_IDMA_IDMA1CONFIG::count |
Number of bytes to be transfered.
The count signifies the number of bytes to be transferred using iDMA channel 1. This must be a multiple of 4 bytes. A count of zero will not transfer any data, but will generate an interrupt if requested.
Transfer Priority.
The transfer priority is used for arbitration between the CPU and DMA accesses when there are conflicts. Valid values for the priority range between 0 and 7.
Boolean Flag to enable/disable CPU interrupt.
When this interrupt flag is set, a CPU Interrupt IDMA_INT1 is raised on completion of the block transfer/fill request.
