Hardware Sniffers: The MISC architecture

Crosstalk: Second Reality · published 6 days ago

All events Players around this date Read on Steam

The Minimal Instruction Set Computer is a 32-bit Sail-validated instruction set architecture created very early in the development of the various parts that comprise Crosstalk, specifically to perform daily computing operations without unnecessary overhead and complexity. MISC defines an array of processor opcodes, flags, and memory rules that dictate how a conforming processor is interfaced with and how it will load, access, and execute.

MISC is separate from any specific processor. The difference is equivalent to the difference when saying "x86" versus "80386." When you see a reference to MISC, such as in a game's target platform list, it means that it runs on the architecture itself, no matter what CPU implements it. Conversely, you may see a game say that it's compatible with a specific MISC CPU, which would mean that a CPU implements something on top of MISC that is unique to itself.

Today, the topic is the DLU, which stands for the DANGLING Logic Unit , and it is the first CPU of the MISC architecture . The DLU consists of the following parts: · dangalu.sv: the DANGLING Arithmetic Logic Unit · dangdsu.sv: the DANGLING Sound Unit · dangddu.sv: the DANGLING Display Unit (80x25 text mode + a framebuffer mode, which some parts…Community3 Sep 2026Dropping old achievements that are no longer achievable at releasePrevious achievements are being removed so that the initial Early Access release state of the game contains only those that can be awarded at that time. They will return once EDA features return.
