whereas others may only require a single byte. In general, the more complex and rarer the instruction, the longer it tends to be. In effect, this acts like a Huffman encoding of the list of work for
whether the last result generated a carry or required a borrow, but is also used to hold bits shifted out with shifts, to record whether the high word of a multiplication is non-zero or not, and other such things (i.e., there are far too many instruction-speci?c effects to list ...

While x86 processors have improved in energy efficiency, advanced RISC machine (ARM-based) central processing units (CPUs) are generally more power-efficient for portable and battery-powered devices due to their reduced instruction set computer (RISC) architecture. ...
单指令多数据(SIMD, Single Instruction Multiple Data)。 MMX整数 提供3种新的整数类型。 64位打包字节整数。 64位打包字整数。 64位打包双字节整数。 8个字节整数,4个字整数或2个双字整数都可以打包到单一的64位MMX寄存器中。 MMX寄存器被映射到FPU寄存器。
The Intel x86 processor uses complex instruction set computer (CISC) architecture, which means there is a modest number of special-purpose registers instead of large quantities of general-purpose registers. It also means that complex special-purpose instructions will predominate. The x86 processor ...
x86 architecture basics like an overview of the instruction set, register set and operating modes The behavior of segmentation, how it was originally intended to be used and how it is actually used by operating systems today (both 32-bit and 64-bit OSs) How to setup system calls using multi...

This is due to the fact that this instruction set has become something of a lowest common denominator for many modern operating systems and probably also because the term became common after the introduction of the 80386 in 1985. 参考译文:在20世纪80年代和90年代初,当8088和80286仍然被广泛使用时...
