摘要： Techniques are disclosed relating to arbitration of requests to access a register file. In one embodiment, an apparatus includes a write queue and a register file that includes multiple entries. In one embodiment, the apparatus is configured to select a request from a plurality of requests based on a plurality of request characteristics, and write data from the accepted request into a write queue. In one embodiment, the request characteristics include: whether a request is a last request from an agent for a given register file entry and whether the request finishes a previous request. In one embodiment, a final arbiter is configured to select among requests from the write queue, a read queue, and multiple execution pipelines to access banks of the register file in a given cycle.
