![]() Zombie mode ? how can you avoid electrical conflicts since there is no suitable BUSREQ line on msx?Īs far i know, no high impedance state no way to do DMA operations.? The FPU unit could do high performance data transfer directly to the VDP/V9990 using my "Z80/R800 zombie mode" technique too, minimizing the performance bottleneck between them. ![]() I think this device could use my "Z80/R800 zombie mode" techniques to improve the data tranfer rate between the FPU unit and the Z80/R800. Particularly combined with a V9990, this opens a whole world of new possibilities for MSX. According to TecnoBytes, using the MSX FPU should make it possible to do realtime calculations for a game that uses "Angry Birds" physics. To make that happen, they have teamed up with the team behind the Oldbits Dev Studio who are going to produce a ready-for-use library to support the MSX FPU. Today, TecnoBytes have announced an upcoming hardware extension for MSX that brings something entirely new to the table: a Floating Point Unit (FPU) for MSX or in other words: a coprocessor that can take the performance of your MSX to the next level, provided there is software written for it. These cards are compatible with the Sunrise MoonSound and GFX9000 cartridges respectively. ![]() Over the past few years Brasil based TecnoBytes have rapidly grown a good reputation as hardware supplier for MSX, with their OPL4 Shockwave sound card and the V9990 PowerGraph as the most well-known products. ![]()
