A coprocessor such as a floating-point unit includes a pipeline that is partitioned into a first portion and a second portion. A controller is configured to provide control signals to the first portion and the second portion of the pipeline. A first physical distance traversed by control signals propagating from the controller to the first portion of the pipeline is shorter than a second physical distance traversed by control signals propagating from the controller to the second portion of the pipeline. A scheduler is configured to cause a physical register file to provide a first subset of bits of an instruction to the first portion at a first time. The physical register file provides a second subset of the bits of the instruction to the second portion at a second time subsequent to the first time.
