Abstract
There is provided a novel microprogrammed processor (100) by combining two or more processor cores (10) in such a way that the processor cores can share the special microprogram memory resource (20) that is located deep inside the processor architecture. In other words, the novel microprogrammed processor (100) basically includes at least two processor cores (10), and a common internal microprogram control store (20) including microcode instructions for controlling at least the internal standard operation of the multiple processor cores, and suitable elements (30) for providing time-shared access to the microprogram control store by the processor cores.
