Abstract:
1. An in-circuit emulation debugger, comprising: a device emulation unit, coupled to a collocated DSP core, for emulating circuitry that is to interact with said DSP core; an external processor interface, coupled to said device emulation unit, that receives control signals from an external processor that cause said device emulation unit to provide a test environment for said DSP core; a breakpoint detection circuit, associated with said device emulation unit, that determines occurrences of events both internal and external to said DSP core that preprogrammed breakpoints are based on and responds to said preprogrammed breakpoints; and a status register, associated with said device emulation unit, that contains data received from said breakpoint detection circuit, said data indicating at least whether an occurrence, associated with said preprogrammed breakpoint, has occurred.
