Abstract
A digital signal processor includes a variable precision hardware pipeline that provides a maximum level of precision using a first plurality of bits for a mathematical representation. The pipeline stages include data registers to store the first plurality of bits. A precision select module selects a level of precision for processing a block of instructions and sets a precision control register. Logic circuitry utilizes the precision control register to gate the clock signal for one or more of the first plurality of bits to reduce the precision of the hardware pipeline. The logic circuitry disables the clock signal for the data latches in the pipeline corresponding to bits to be disabled to reduce the precision. By disabling the clock signal for the data registers, the amount of power consumed by the pipeline can be reduced.
