摘要:
An apparatus and method for simulating a multi-ported memory using lower port count memories as banks. A collector units gather source operands from the banks as needed to process program instructions. The collector units also gather constants that are used as operands. When all of the source operands needed to process a program instruction have been gathered, a collector unit outputs the source operands to an execution unit while avoiding writeback conflicts to registers specified by the program instruction that may be accessed by other execution units.
