Abstract:
Hardware units and methods for performing matrix multiplication via a multi-stage pipeline wherein the storage elements associated with one or more stages of the pipeline are clock gated based on the data elements and/or portions thereof that known to have a zero value (or can be treated as having a zero value). In some cases, the storage elements may be clock gated on a per data element basis based on whether the data element has a zero value (or can be treated as having a zero value). In other cases, the storage elements may be clock gated on a partial element basis based on the bit width of the data elements. For example, if bit width of the data elements is less than a maximum bit width for the data elements then a portion of the bits related to that data element can be treated as having a zero value and a portion of the storage elements associated with that data element may not be clocked. In yet other cases the storage elements may be clock gated on both a per element and a partial element basis.

Claim (Index 1):
A hardware unit to perform a matrix multiplication, the hardware unit comprising:\n a multiplier stage comprising a plurality of multipliers, each multiplier configured to multiply a first data element and a second data element to produce a multiplication data element; one or more adder stages following the multiplier stage that form an adder tree to produce a sum of the multiplication data elements, each adder stage comprising one or more adders configured to add at least two data elements output by a previous stage to produce an addition data element; wherein at least one multiplier and/or at least one adder is preceded by a storage element corresponding to each bit of the data elements input to the at least one adder and/or the at least one multiplier; and control logic configured to clock gate all or a portion of the storage elements corresponding to a data element in response to determining that all or a portion of that data element can be treated as having a zero value.
