The increasing complexity of programming environments provides a number of opportunities for assembly language programmers. 32/64-Bit 80x86 Assembly Language Architecture attempts to break through that complexity by providing a step-by-step understanding of programming Intel and AMD 80x86 processors in assembly language. This book explains 32-bit and 64-bit 80x86 assembly language programming inclusive of the SIMD (single instruction multiple data) instruction supersets that bring the 80x86 processor into the realm of the supercomputer, gives insight into the FPU (floating-point unit) chip in every Pentium processor, and offers strategies for optimizing code.
