Dear all, I encounter a probelm of 6455's Giga Ethernet these days. When I test the Giga Ethernet 's thoughput between the DSP and a PC,I find that if the DSP's core clock frequency is 1GHz, the maximum throughput is only 520Mbits/s, if the DSP's core clock frequency is 1.2GHz, the maximum throughput is only 680Mbits/s. Does the DSP's clock frequency limit the performance of the Giga Ethernet? Can we increase the throughput? NDK V1.94 AND tcp/ip socket are used.
