Microprocessor and execution method thereof

Abstract

The invention provides a microprocessor and an execution method thereof. The microprocessor comprises a plurality of processing cores each of which instantiates the visible storage resources on the respective architectures. A first processing core of the above plurality of processing cores meets an architecture instruction, uses a value appointed by the above architecture instruction to indicate the first processing core to update the visible storage resources on the respective architectures of the first processing core. In order to respond to meet the above architecture instructions, the above first processing core provides the above numerical values to each of the above plurality of processing cores and uses the above values to update the visible storage resources on the respective architectures of the first processing core. Each of the processing core, except the first processing core uses the above value provided by the first processing core to update the visible storage resourceson the respective architectures of the first processing core on the condition of not meeting the above architecture instruction.

Description

[0001] This application is a divisional application of the application dated August 28, 2014, the application number is 201410431675.1, and the invention title is "Microprocessor and its execution method". technical field [0002] The present invention pertains to a microprocessor, and in particular to per-core real-time architecture visible storage update propagation. Background technique [0003] The increase in multi-core microprocessors is primarily due to the performance advantages they offer. This may be primarily due to the rapid reduction in the size of the geometric dimensions of semiconductor devices, thereby increasing transistor density. The existence of multiple cores in a microprocessor has created the need to communicate with one core and other cores to perform various functions such as power management, cache management, debugging, and configuration associated with more cores. [0004] Traditionally, programs (eg, operating systems or applications) running o...
