Hi Experts,
I am asking for my customer urgently. Thanks.
We use for traversal function (one time 4 bytes are int type) for testing, both use cache and CCS optimization level opened to L2 level,
1.Code runs in SRAM, but data would in SRAM and DDR:
SRAM to SRAM 666MB/s
DDR to SRAM 122MB/s
SRAM to DDR 308MB/s
DDR to DDR 90MB/s
2.Code runs in DDR, and data also DDR:
DDR to DDR 89MB/s.
You can see the test data above, when the data and code both SRAM, it would be It is seven times that of DDR.(666MB/s Vs 89MB/s)
Also CPU reading and writing DDR speed very slow. Because we see the DDR up to support 1600MB/s. Could you give me suggestion here?
