| | | | | 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 ... | |

| | | | | 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. Memory Operations We already have a small RAM which holds our instruction stream, but our TPU ISA defines memory read and write instructions, and we should get those instructions working. It's the last major functional implementation we need to complete. The fetch stage is simply a memory read with the PC... | |

| | | | | The "central processing unit" (CPU) is the device that sifts through information and turns it into other information. It's an implementation of an "instruction set architecture" (ISA). Lately, most general-purpose computers have more than one CPU inside its main "chipset". Engineers call them "cores", so it's a "dual-core processor" or "quad-core processor" or whatever size [...]Read More... from CPU: How Does a Computer Work Through Code? | |
