Registers are fast, local slots inside a processor in which applications can store values that will be needed shortly. Data stored in registers is available for reuse at full processor speeds and is faster than even cached data in on-chip cache. The x86 architecture, with only eight general-purpose registers, is significantly register-poor as compared to Reduced Instruction Set Computing (RISC) processors. Additionally, the x87 floating-point architecture is stack-oriented: Every floating-point arithmetic instruction requires at least one of the operands to be on top of the stack, leading to significant inefficiencies and relatively poor floating-point performance.
