Abstract

An integrated circuit device has a first central processing unit including a digital signal processing (DSP) engine, and a plurality of contexts, each context having a CPU context with a plurality of registers and a DSP context, wherein the DSP context has control bits and a plurality of DSP registers, wherein after a reset of the integrated circuit device the control bits of all DSP context are linked together such that data written to the control bits of a DSP context is written to respective control bits of all other DSP contexts and only after a context switch to another context and a modification of at least one of the control bits of the another DSP context, the control bits of the another context is severed from the link to form independent control bits of the DSP context.
