Hi,
I am working on syslib for ARM to DSP communication. I am using CCS Version: 6.0.1.00040, syslib_2_00_08_00 for DSP and DEV.SC-MCSDK-02.02.01.03A for ARM.
Do you have any benchmarking for msgcom transfer between ARM and DSP on TI 6614?
I am profiling the delay for the basic queue ring(test_queue_ring_basic_reader for Msgcom_ChannelMode_NON_BLOCKING) ARM writer DSP reader example for 1- iteration transferring 64bytes from ARM to DSP. The way I checked the delay is by checking the difference in CPU cycle after the Agent_push (agentHandle, channelName, ResMgr_NamedResourceType_INTERNAL_SYSLIB, Agent_NamedResource_CREATE, &errorCode) < 0) and after Msgcom_getMessage in Msgcom_ChannelMode_NON_BLOCKING. I find the latency to be of the order 10ms. Is such high latency expexted?
Thanks and regards,
Shabrin
