Hi. I have an ADSP-BF533 EZ-KIT LITE REV 1.1. Right now, I am very interested in DMA performance of BF533. I need a code example to DMA data from one SRAM to the other SRAM. I have some code that works well (essentially modifying the MemDMA example that comes with the kit). However, the cycle consumption of SRAM->SRAM transfer is worse than SDRAM(external)<->SRAM. I guesss SRAM->SRAM DMA should be faster than SDRAM<->SRAM. (I am measuring the number of cycles using the CYCLES register) Regards MB |
