Minimax – A Compressed-First, Microcoded RISC-V CPU▲171
RISC-V's compressed instruction (RVC) extension is intended as an add-on to the regular, 32-bit instruction set, not a replacement or competitor. Its designers intended RVC instructions to be expanded into regular 32-bit RV32I equivalents via a pre-decoder. What happens if we explicitly architect a RISC-V CPU to execute RVC instructions, and "mop up" any RV32I instructions that aren't convenient via a microcode layer? What architectural optimizations are unlocked as a result? "Minimax" is an experimental RISC-V implementation intended to establish if an RVC-optimized CPU is, in practice, any…

RISC-V assembly tabletop board game (hack your opponent)▲400
I made this game to teach my daughter how buffer overflows work. I want her to look at programs as things she can change, and make them do whatever she wants. Building your exploit in memory and jumping to it feels so cool. I hope this game teaches kids and programmers (who seem to have forgotten what computers actually are) that its quite fun to mess with programs. We used to have that excitement few years ago, just break into softice and change a branch into a nop and ignore the serial number check, or go to a different game level because this one is too annoying. While working on the game…

MyraOS – My 32-bit operating system in C and ASM (Hack Club project)▲247
Hi HN, I’m Dvir, a young developer. Last year, I got rejected after a job interview because I lacked some CPU knowledge. After that, I decided to deepen my understanding in the low level world and learn how things work under the hood. I decided to try and create an OS in C and ASM as a way to broaden my knowledge in this area. This took me on the most interesting ride, where I’ve learned about OS theory and low level programming on a whole new level. I’ve spent hours upon hours, blood and tears, reading different OS theory blogs, learning low level concepts, debugging, testing and working on…
