Was watching a @techconnectify.bsky.social video and was wondering, is that CPU in the MCU a SuperH chip? From what I could find, yeah! SH-2A, SH-7055. SuperH go brrrr

Image of the insides of a Motor Control Unit showing the chips on board, the board has the serial number A56-001.

Went through hell and back again to implement this hand-scheduled, manually pipelined routine in pure SH4 assembly to basically implement glRotatef()... except hardware accelerated for the Sega #Dreamcast's SH4 FPU! 1.25-2.13x faster than CGLM! #retrocomputing #cpp #gamedev #math #graphics

Presenting shz_xmtrx_blend(): a new SH4 assembly routine for my fast math library targeting the Sega #Dreamcast! It allows you to multiply and accumulate weighted joint matrices into a single skin matrix, maintained within the 4x4 FP register back-bank for maximum GAINZ! #gamedev #simd #cpp

Falco Girgis @falcogirgis.bsky.social · 16/08/2026

Busted out my trusty #moleskine notebook and had to hand write SH4 ASM while visualizing the XMTRX FP register back-bank of the SH4 CPU in the Sega #Dreamcast to fully optimize this routine. SH4ZAM equivalent to glScalef() in #OpenGL: github.com/gyrovorbis/s... #gamedev #vectorization #simd #cpp

Big ol' GAINZ on the FPU in the #Sega #Dreamcast when applying a translation matrix, after increasing superscalar dual dispatch rate of the processor by finding a novel way to zero out two FP registers in parallel, using two different but parallel-issued instructions. #retrocomputing #simd #gamedev

Diddy Kong Racing: #Nintendo64 Original vs our WIP #SegaDreamcast Port It's been so long since I played on N64, and I've had my head down so deep in the code, fighting for every 0.1FPS win, that I had started to lose sight of how our port even compares... Reality check. #gamedev #retrogaming

12 hours since I've been given access to the #DiddyKong Racing codebase for the Sega #Dreamcast port, and I've already managed to create an "incident" worthy of the scrapbook... The gainz from accelerating the trig routines for the SH4 were so big, their necks got swole too! #gamedev #retrogaming
