INTEGRATED CIRCUIT DEVICE COMPRISING CLOCK GATING CIRCUITRY, ELECTRONIC DEVICE AND METHOD FOR DYNAMICALLY CONFIGURING CLOCK GATING

摘要

An integrated circuit (100) comprises clock gating circuitry (140) comprising at least one gating component (210, 220) located within a clock distribution network (120) and arranged to enable at least one part of the clock distribution network (120) to be gated, and gating control circuitry (230, 240) arranged to cause the at least one gating component (210, 220) to disable the at least one part of the clock distribution network (120) upon certain conditions being fulfilled. The clock gating circuitry (140) further comprises clock gating disabling circuitry (250, 260) configurable to enable the gating of the at least one part of the clock distribution network (120) to be disabled.
