FIELD OF INVENTION This invention relates to computer graphics processing, and more specifically to computer graphics processing using two or more architecturally distinct graphics processors. BACKGROUND OF INVENTION Many computing devices utilize hi
A real-time operating system (RTOS) for use with minimal-memory controllers has a kernel for managing task execution, including context switching, a plurality of defined tasks, individual ones of the tasks having subroutines callable in nested levels
A context switch (also sometimes referred to as a process switch or a task switch) is the switching of the CPU (central processing unit) from one process or thread to another. A process (also sometimes referred to as a task) is an executing (i.e., ru
How many Context Switches is “normal”? This depends very much on the type of application you run. If you've got applications which are very trigger-happy WRT syscalls you can expect to see high amounts of context switching. If most of your applicatio
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

I was recently reading a series on “Write Sequential Non-Blocking IO Code With Fibers in NodeJS” by Venkatesh. Venki was essentially trying to emphasize that writing non-blocking code in NodeJS (either via callbacks, or using promises) can get hairy
Process program program==code+data; 一个进程可以对应多个程序,一个程序也可以变成多个进程.程序可以作为一种软件资源长期保存,以文件的形式存放在硬盘 process: 相应的程序+CPU上下文+一组系统资源 动态性, 独立性, 并发性 一个CPU,任何时刻最多只能有一个进程去使用它 process VS thread 进程的资源分配的基本单位,是分配资源的抽象:进程把一组相关资源组合起来,构成了一个资源平台,或者说资源环境,包括运行上下文,内存地址空间,打开的文
