In this short guide, I don't talk about floating point assembly instructions to don't make it too long, if you want know more about, you can see the ARM Architecture Reference Manual. Apr 9, 2014 - Complex Instruction Set Computer (CISC) processors, like the x86, have a rich instruction set capable of doing complex things with a single instruction. Sep 27, 2013 - When the Intel architecture moved from 32-bit to 64-bit, the number of registers was doubled from 8 to 16, and this made for a substantial performance improvement. Jan 10, 2012 - When the x86 architecture gained 64-bit support, not only were the registers expanded to 64-bit, the register set itself was expanded to 16 general-purpose registers, 16 MMX-technology registers and 16 SSE-technology registers. Provides 32 64-bit registers for Advanced SIMD vector and scalar floating-point support. By long custom, an N-bit CPU implements an ISA (instruction set architecture) with N-bit integer registers and N (or nearly N) address bits, ignoring sizes of buses or floating-point registers. Mar 1, 2014 - Intel, Assembler - Englisch - x86 Assembly Instruction Set Reference (PDF) James Leterman, 32-64-BIT 80 x 86 Assembly Language Architecture (CHM) James T. 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 allows for the assembly to do away with some instructions by just making them alias to others: for example, there is no instruction to load small immediate values onto a GPR. Such processors often and link register (LR). Assembly Language Programmers: Roll Call. Mac OS X on x86-64, for example, only uses 47 bits of a pointer. The floating-point registers are . For example, consider the overly long, often awkward, and sometimes contentious process by which 32-bit microprocessor systems evolved into 64/32-bitters needed to address larger storage and run mixtures of 32- and 64-bit user programs.
