OPERAND CONFLICT RESOLUTION FOR REDUCED PORT GENERAL PURPOSE REGISTER

摘要

Techniques are described for determining whether execution of an instruction would require reading more values from a memory cell of a general purpose register (GPR) than a read port of the memory cell would allow. In such a case the techniques may store prior to execution of the instruction one or more values from the memory cell in a separate conflict queue. During execution of the instruction to implement an operation defined by the instruction one value that is an operand of the operation would be read from the memory cell and another value that is an operand of the operation other would be read from the conflict queue.
