![]() This is what allowed the playstation to do its fast processing of Geometry such as 3D models, animation and effects. ![]() The Geometry Transformation Engine (GTE) is on of the co-processors attached to the main processor, specifically designed to do fast maths operations. This allows the main processor to focus on game logic while the system co-processor handled all the lower-level details 3. The System control co-processor was the part of the CPU that handled memory management, interrupts and hardware breakpoints. There was actually only 2 co-processors in the CPU named COP0 and COP2 as COP1 and COP3 were not present in the chip. However, I have run into a snag in which I have all the documentation I need for my other components but am missing a good/decent wiring diagram for the N64. The CPU used for the Playstation was not just a simple MIPS R3000A, it was partnered with additional co-processors to handle system resources and geometry processing. I am a computer engineering student looking to do his own version of the Ultra HDMI project found here: UltraHDMI - Enjoy your Nintendo 64 with modern HDMI. If you thought that the Nintendo 64 was the only console that partnered with SGI for this generation of consoles you would be mistaken, the CPU for the original playstation used technology licensed from SGI and build by LSI Logic Corp 2.
