The K5TM microprocessor project at AMD created the basis for Advanced Micro Devices' first independently designed implementations of the x86 architecture. The first-time nature of this project, coupled with the complexity of the x86 architecture, presented many unique challenges and constraints to the designers. Nevertheless, the end result is the only x86-compatible microprocessor architecture that can speculatively decode and execute up to four x86 instructions at a time, with out-of-order instruction execution. An equally significant result of the project is a very robust x86 development and verification methodology.
