Dear Mouloud,

I think that the main approach to test a mapping algorithm is to simulate it with, e.g., HeMPS or NoCSim, and measure power consumption and performance. The main idea is that the different placement of application tasks affects these objectives. Therefore, by comparing results you can find an optimal solution.

I'm not aware of special benchmarks used for NoC mapping. Often multimedia examples have been used in the literature (e.g. H264), but not in a standardized way.

I recommend you to use SPLASH which can be found here:

I prefer to use

SPLASH2, parallel scientific workloads

SPLASH2 is for chip multicore processors but for heterogeneous noc, E3S is quite popular and for multimedia you may refer the following paper:

Unimap platform may be used for testing noc mapping

For the benchmarks to use, it depend on the tools that you are using, if you use GEM5 there are some benchmarks to use. In otherwise the most popular benchmarking used in the field of NoC mapping are the multimedia applications like MPEG4,
