Abstract
The present invention generally relates to multiply-accumulate units for use in digital signal processors. Each multiply-accumulate unit includes a multiply unit which is coupled with two or more dedicated accumulators. Because of the coupling configuration, when an instruction specifies which accumulator should be used in executing an operation, the instruction need not specify which multiply unit should be utilized. A scheduler containing a digital signal processor's coupling configuration may then identify the multiply unit associated with the accumulator and may then forward the instruction to the identified multiply unit. Multiply-accumulate units can be configured to execute both scalar and vector operations. For executing vector operations, multiply units and their coupled accumulators are configured such that each may be easily grouped with other multiply units and accumulators.
