REX前缀使得指令能够访问这些新的64位寄存器。 指定64位操作数大小: REX前缀能够指示指令使用64位的操作数。默认情况下,指令使用32位操作数,但在64位模式下,REX前缀使得处理器能够处理64位的数据。例如,进行64位加法或64位数据传输时需要REX前缀。 指定扩展寄存器: 除了通用寄存器外,REX前缀还可以用于扩展SSE寄存器的...
x64 is a generic name for the 64-bit extensions to Intel's and AMD's 32-bit x86 instruction set architecture (ISA). AMD introduced the first version of x64, initially called x86-64 and later renamed AMD64. Intel named their implementation IA32e and then EMT64. There are some slight ...
