In a computing system, cache coherency is performed by selecting one of a plurality of coherency protocols for a first memory transaction. Each of the plurality of coherency protocols has a unique set of cache states that may be applied to cached dat…

A method includes storing, with a first programmable processor, shared variable data to cache lines of a first cache of the first processor. The method further includes executing, with the first programmable processor, a store-with-release operation,…

A hypervisor calculates the total number of processor cycles (the number of processor cycles of one or more physical processors) in a first length of time based on the sum of the operating frequencies of the respective physical processors and the fir…

A method and mechanism for performing an unconditional stack switch in a processor. A processor includes a processing unit coupled to a memory. The memory includes a plurality of stacks, a special mode task state segment, and a descriptor table. The…

A trusted computer system that offers Linux® compatibility and supports contemporary hardware speeds. It is designed to require no porting of common applications which run on Linux, to be easy to develop for, and to allow the use of a wide variety of…

How to describe the wind sprial in computer system? 2017-02-21 刘崇军 风螺旋线 If we want get the approval of ICAO, we must separate the theory to different parts, which is easy to be adopted and which is not. Let's talk about the easy part of wind spiral t…

A system switches between non-secure and secure modes by making processes, applications, and data for the non-secure mode unavailable to the secure mode and vice versa. The process thread run queue is modified to include a state flag for each process…
