An opcode is the portion of a machine language instruction that specifies the operation to be performed. A kernel is the main component of most computer operating systems (OS); it is a bridge between applications and the actual data processing done at the hardware level. Device drivers are ...
写在前面在前面的三讲中,我们从例子、优化方法、位运算等角度认识了软件的性能优化,接下来我们向底层探索从编译到硬件的一系列内容。本文将简单的介绍编译和指令集相关的内容。 编译学过编译原理的同学应该了解…

There are even subtler ways in which a real deadlock might occur in your program. Soft deadlocks—where an application appears to have deadlocked, but has really just gotten stuck performing a high-latency or contentious operation—are problematic, too. Computation-intensiv...
Supposemain()is implemented in assembly language andmain.sis self-contained, then simply: gcc main.S Often, you will want to enable the debuggergdborlldb. Do this: gcc -g main.S Without the-gcommand line option, your debugger may not properly operate. ...
Focusing on a modern architecture (the Java Virtual Machine, or JVM), this text provides a thorough treatment of the principles of computer organization in the context of today’s portable computer. Students are given simple but realistic examples to gain a complete understanding of how computation...
