![]() ![]() The later DSP-1A and DSP-1B serve the same purpose as the DSP-1. It also provides fast support for the floating point and trigonometric calculations needed by 3D math algorithms. It is used as a math coprocessor in games such as Super Mario Kart and Pilotwings that require more advanced Mode 7 scaling and rotation. The DSP-1 is the most varied and widely used of the SNES DSPs, appearing in over 15 separate titles. All of them are based on the NEC µPD77C25 CPU and clocked at 8Mhz. The DSP-1 version, including the later 1A die shrink and 1B bug fix revisions, was most often used the DSP-2, DSP-3, and DSP-4 were used in only one title each. Four revisions of the chip exist, each physically identical but with different microcode. This series of fixed-point digital signal processor chips allowed for fast vector-based calculations, bitmap conversions, both 2D and 3D coordinate transformations, and other functions. The differences arise in how they are packaged, their pinout, their maximum supported ROM size, and their internal clock speed. All versions of the Super FX chip are functionally compatible in terms of their instruction set. The final known revision is the GSU-2-SP1. Later on, the design was revised to become the GSU-2, which is still 16-bit, but unlike the earlier Super FX chips, this version can support a ROM size greater than 8 MBit. Both the MARIO CHIP 1 and the GSU-1 can support a maximum ROM size of 8 Mbits. The GSU-1 however runs at the full 21 MHz. Both versions are clocked with a 21 MHz signal, but an internal clock speed divider halves it to 10.5 MHz on the MARIO CHIP 1. The following year, some boards were providing an epoxy version of it, and later a first revision came out under the label "GSU-1". This chip went through at least four revisions, first starting out as a surface mounted chip labeled "MARIO CHIP 1" (Mathematical, Argonaut, Rotation & I/O) in the earliest Star Fox cartridges, commonly called the Super FX. Super Mario World 2: Yoshi's Island uses the Super FX 2 for sprite scaling, rotation, and stretching. In addition to rendering polygons, the chip can assist the SNES with advanced 2D effects. It is typically programmed to act as a graphics accelerator chip that draws polygons to a frame buffer in the RAM sitting adjacent to it.
