Hello.
I have to copy a huge data through SRIO. I read a post http://e2e.ti.com/support/dsp/tms320c6000_high_performance_dsps/f/112/p/37583/131293.aspx#131293 where RandyP wrote:
“However, you can program a DMA channel to copy the columns to an intermediate buffer. That DMA channel could then chain to another DMA channel that copies 6 words from a table to a set of LSU registers to initiate the transfer…”
I have tried to do this but I have a problem.
When transaction is completed I should clean LSU_ICSR reg and set INTDST_RATE_CNTL register.
Now I set these registers in the interrupt.
But setting data to these registers is very slow (near 400 tiks per interrupt).
I can create a chain of EDMA (when SRIO event is occurred, first DMA request set LSU_ICSR. After that, the next request in the EDMA chain sets INT_DST_RATE_CNTL, next the EDMA request sets SRIO_LSU_REG) but it is awkward.
Can I set it in automatic mode (without entering in the interrupt and setting it there)?
