各位专家好,我的软硬件环境为ccsv5.5,6678(非evm板)。
TI文档介绍HyperLink 的设计速度最高速率支持 12.5Gbps,但是在K1_STK_v1.1中的Hyperlink例程中,速率最高只有1002 MB/s。
Hyperlink例程打印部分内容
noncacheable, nonprefetchable memory copy
1002 MB/s, copy 65536 bytes from 0x820000 to 0x41800000, consumes 65342 cycles
42 MB/s, copy 65536 bytes from 0x41800000 to 0x820000, consumes 1548292 cycles
40 MB/s, copy 65536 bytes from 0x41800000 to 0x41810000, consumes 1621974 cycles
32KB L1D cache, prefetchable memory copy
752 MB/s, copy 65536 bytes from 0x820000 to 0x41800000, consumes 87114 cycles
294 MB/s, copy 65536 bytes from 0x41800000 to 0x820000, consumes 222244 cycles
236 MB/s, copy 65536 bytes from 0x41800000 to 0x41810000, consumes 276667 cycles
32KB L1D cache, 256KB L2 cache, prefetchable memory copy
500 MB/s, copy 65536 bytes from 0x820000 to 0x41800000, consumes 131065 cycles
498 MB/s, copy 65536 bytes from 0x41800000 to 0x820000, consumes 131364 cycles
339 MB/s, copy 65536 bytes from 0x41800000 to 0x41810000, consumes 193026 cycles
我想请教各位专家,Hyperlink例程需要哪部分的修改,让速率提升。谢谢
