Abstract:
Techniques disclosed herein describe a variable latency pipe for interleaving instruction tags in a processor. According to one embodiment presented herein, an instruction tag is associated with an instruction upon issue of the instruction from the issue queue. One of a plurality of positions in the latency pipe is determined. The pipe stores one or more instruction tags, each associated with a respective instruction. The pipe also stores the instruction tags in a respective position based on the latency of each respective instruction. The instruction tag is stored at the determined position in the pipe.
