MULTI-CORE PROCESSOR, MULTI-CORE SYSTEM AND ELECTRONIC DEVICE INCLUDING THE SAME, AND METHOD OF SHARING CACHE IN MULTI-CORE PROCESSOR

摘要

PURPOSE: A multi-core process, a multi-core system, an electronic device, and a cache sharing method of the multi-core process are provided to operate cores by sharing a command cache and effectively relay the collision of command request signals between the cores, thereby reducing the whole size and increasing an operation speed. CONSTITUTION: A command cache (200) stores commands. Cores (100-1~100-n) share the command cache. The cores successively perform the operations corresponding to the commands by receiving the commands corresponding to continuous addresses from the command cache. The cores include buffers (110-1~110-n) which execute the commands which are received from the command cache. The cores successively perform the operations corresponding to the commands stored in the buffers.
