specification of the modern x86 instruction set architecture?" 1.2 The Problem Instruction set architecture (ISA) is an interface between a processor and software. In other words, an ISA is a high-level processor description that provides enough infor-mation for a programmer to write and reason about low-level software. Ideally an ISA

X86 History It’s quite amazing that this architecture has witnessed so little (fundamental) change since the 8086 Backward compatibility Imposed early as _the_ ISA (Intel was the first company to produce a 16-bit architecture) Some argue that it’s an ugly ISA Due to it being a set of add-ons rather than a modern re-design But it’s relatively easy to implement in hardware, and Intel’s

" Complex Instruction Set Computing e.g x86 " Larger instruction set " More complicated instructions built into hardware " Variable length " Multiple clock cycles per instruction " Reduced Instruction Set Computing e.g. ARM " Small, highly optimized set of instructions " Memory accesses are specific instructions " One instruction per clock cycle
