| | | | | I got into FPGAs with the intent of building a retro-computer. A couple of popular hardware implementation targets are Gameboy, NES, RISC-V and CHIP-8. Last year Ive done my practice round with 6502 and RISC-V emulators, both in C. CHIP-8 is a really nice virtual machine implemented on a number of computers since the 1970s, initially designed to make game development easier. After building a CHIP-8 emulator a couple of days ago I thought I know a lot about the simple platform to actualy start implementin... | |

| | | | | 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! ISE WebPACK Design Software I'm using the Xilinx ISE WebPack suite of tools for this project. It's available here for Windows and Linux, for free. Once installed and set up, you can run the project navigator and create a new project. I'll go through some basic steps here, just for clarity - however this s... | |

| | | David Patterson had recently mentioned that (rephrasing): The programmers may benefit from using complex instruction sets directly, but it is increasingly challenging for compilers to automatically generate them in the right spots. In the last 3-4 years I gave a bunch of talks on the intricacies of SIMD programming, highlighting the divergence in hardware and software design in the past ten years. Chips are becoming bigger and more complicated to add more functionality, but the general-purpose compilers like GCC, LLVM, MSVC and ICC cannot keep up with the pace. Hardly any developer codes in Assembly today, hoping that the compiler will do the heavy lifting. | ||
