If you change the values in the py files in the source tree you need to re-compile the binary.
You can go to all the bridges and in the config files and change their sizes: something like: system.iobridge.req_size_a = 64 Ali On 28.03.2012 00:12, Teng Lu wrote: > Hi All, > > I've also tried to modify src/mem/Bridge.py from > req_size_a = Param.Int(16, "The number of requests to buffer") > req_size_b = Param.Int(16, "The number of requests to buffer") > resp_size_a = Param.Int(16, "The number of requests to buffer") > resp_size_b = Param.Int(16, "The number of requests to buffer") > > to > req_size_a = Param.Int(64, "The number of requests to buffer") > req_size_b = Param.Int(64, "The number of requests to buffer") > resp_size_a = Param.Int(64, "The number of requests to buffer") > resp_size_b = Param.Int(64, "The number of requests to buffer") > > but it still gives me the same error.

However, I didn't find any code in src/mem/bridge.hh or src/mem/bridge.cc regarding buffer size. Could anybody tell me how to increase the buffer size?
