Abstract
The present invention provides a processor device and technique having the capability of providing a two-processor solution with only one processor. In accordance with the principles of the present invention, a host processor is programmed in its native source and machine code language, and an emulated second processor is programmed in a different native source or machine code language particular to that emulated processor, to allow programming specialists in the different processors to develop common code for use on the same host processor. A multitasking operating system is included to allow time sharing operation between instructions from program code relating to the host processor (e.g., a DSP in the disclosed embodiment), and different program code relating to the emulated processor. The program code relating to the host processor (e.g., DSP) is written in program code which is native to the DSP, while the program code relating to the emulated processor (e.g., microcontroller) is written in program code which is native to the microcontroller. The SoftCore emulation module allows both DSP code and control code written for a microcontroller to execute independently on the same processor by multi-tasking resources in the faster, host processor (e.g., in the DSP), giving equal time slots of processor time to each processor (real and emulated).
