Hi All,
We are working on a project with AM3517 processor. Our board has a FPGA connected to this processor through GPMC interface in 16bit mode. GPMC accesses FPGA through synchronous burst of 8 words. Our customer wants 128Mbps(16MBps) throughput through DMA from GPMC to SDRAM transactions. We are currently observing only about 32Mbps(4MBps).
Details of the setup:
Processor: AM3517
Clocking rate (Crystal/Core/MPU): 26.0/332/500 MHz
GPMC CLK: 83MHz
GPMC data width: 16bits
GPMC mode: synchronous with 8 word burst
Device connected to GPMC: FPGA
Linux BSP distribution: TI PSP. 04.02.00.07
Kindly let me know your suggestions on how to achieve this.
