SEGA SATURN DEVELOPER'S MANUAL

DSP(Digital Signal Processor): This is a dedicated high-speed arithmetic circuit that mainly performs high-speed operations (multiplication / addition).
Gouraud shading: Gouraud is a kind of calculation algorithm. It is a process that calculates the color of each position (dot, pixel) of each displayed object, and performs calculations such as “light where the light is shining and dark where it is shadowed”.
C3: This is an error process and indicates that error correction cannot be performed when data is read from a CD.
Frame buffer: RAM for storing pictures to be displayed. The line buffer has a restriction on the picture that is arranged in the horizontal direction, but since there is enough RAM for the TV screen, there is no restriction on the horizontal direction.
Pixel: Unit for representing pixels in drawing.
Pulse Code Modulation sound generator: This is a method in which sound is converted to PCM data and stored in memory, and the sound is read out from the memory during performance.
Interlace: One of the image output scanning methods, which obtains one frame image by scanning twice.
