By "resources", I assume you are referring to each of the stage in the out-of-order pipeline? Those stages' implementation codes (fetch, decode, rename, etc..) are located inside the cpu/o3 directory. Branch prediction typically is done in fetch stage, so if you look inside the fetch.hh source code, it includes the header file of "cpu/pred/bpred_unit.hh". So if go up one level, to the cpu/pred directory, that is where the branch predictor implementation code is located.
As far as value predictor, I am not sure how you are going to implement it, but it probably needs to work with or link to other stages/resources such as iew, instruction queue, rob.. Hope this helps.
