Multi-core processor, controlling method thereof and computer system with such processor

摘要

A multi-core processor includes M cores. If the multi-core processor is operated under a non-multiprocessing support operating system, only a single core is configured as a central processing unit and N cores are configured as co-processors, wherein M and N are positive integers, and N is smaller than M.

1. A computer system, comprising:
a first multi-core processor with a first core and a second core; a peripheral component; a memory; and a memory controller connected with the memory, the first multi-core processor, and the peripheral component, wherein the memory is accessible to the first multi-core processor and the peripheral component; wherein the computer system is configured to have said first core as a first central processing unit and configured to have said second core as a first digital signal processor when said first multi-core processor is operated under a non-multiprocessing support operation system, and running said non-multiprocessing support operating system; and wherein the computer system is configured to have said first core as said first central processing unit and configured to have said second core as a second central processing unit when said first multi-core processor is operated under a multiprocessing support operation system, and running said multiprocessing support operating system.
