Abstract

Disclosed are devices, systems, and methods for performing time-domain multiply-and-accumulate (MAC) computations. In some embodiments, an apparatus comprises first and second circuits. The first circuit is configured to (a) perform a first multiplication in response to a trigger signal, the first multiplication being a product of a first value and a second value, and (b) generate a completion signal, wherein the completion signal indicates completion of the first multiplication. The second circuit is coupled to the first circuit and is configured to (i) perform a second multiplication in response to the completion signal, the second multiplication being a product of a third value and a fourth value, and (ii) generate an output signal, wherein the output signal indicates completion of the second multiplication. An amount of elapsed time between the trigger signal and the generation of the output signal represents a sum of the first and second multiplications.
