K1_STK_v1.1中的Hyperlink速率问题

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
