ABSTRACT:
A variable speed floating point unit comprising: 1) an execution pipeline comprising a plurality of execution stages capable of executing floating point operations in a series of sequential steps; and 2) a clock controller capable of receiving an input clock signal and generating a variable speed output clock signal capable of clocking the execution pipeline. The clock controller adjusts a speed of the variable speed output clock signal according to a level of queued opcodes waiting to be executed in the execution pipeline.
