Hi all, my research is to design an inter-processor communicaion protocol in heterogeneous multi-processor platform. and i used Davinci dm6446 to implement it (communication between ARM core and DSP core).
currently i decide to measure the three time intervals to evaluate the efficeincy: 1. from sender issues "send" to the function call returned. 2. from sender send the data to receiver receive the data. 3. from receiver issues "receive" to the function returned. but i am not sure how to arrange the order of sender and receiver, for instance, when i want to measure all those three intervals should sender and receiver issue "send" and "receive" respectively at the same time, or sender first, or receiver first, or all three cases should measure respectively? (data length versus these three time intervals) to evaluate an IPC protocol efficient or not, what others i can measure? any suggestions are welcome. thanks for your help! best, kashin lin
