Abstract

See full text

Technology is described for an asynchronous wrapper circuit for a clock gating cell (CGC). In one example, the asynchronous wrapper cell for CGC includes circuitry configured to (1) sample a data channel via sampling circuitry for a communication start signal to enable the CGC to start a gated clock for a data message on the data channel, and (2) reset an enable of the CGC to an idle mode via idle mode control circuitry after the data message has been clocked via the CGC through function cell circuitry. The idle mode control circuitry generates an output for the sampling circuitry from the function cell. Various other computing circuitries are also disclosed.
