| | | | | This is part of a series of posts detailing the steps and learning undertaken to design and implement a CPU in VHDL. Previous parts are available here, and I'd recommend they are read before continuing! Instruction Set Architecture The Instruction Set Architecture (ISA) of a CPU defines the set of operations that can be performed, and on what data types. It explains timing, restrictions, and sometimes any hazards or hardware bugs that can present during normal operation. The operations are defined along ... | |
