| | | | | Emulators So... what is an emulator? Let's say you want to play an old game from the MS-DOS era. You have the DUKE3D.EXE file, you launch it and ...nothing happens. But why? Old systems had a different architecture from your PC. Loosely speaking, your PC doesn't recognize the program and refuses to execute it. You | |

| | | | | 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... | |

| | | [AI summary] This article dives into the internals of the RI5CY core, a 4-stage in-order pipelined RISC-V core. It discusses the decoder and register file, essential for customizing the core, particularly for adding new instructions and integrating cryptographic extensions like XCrypto. The article also compares RISC-V's compressed instructions with ARM's Thumb mode, highlighting differences in code density and implementation. | ||
