Audio Interface (AI) reads data from the audio buffer using a fixed time interval, and sends it to the DA (digital-to-analog) converter (audio DAC) to produce the sound output.Video Interface (VI) reads data from the frame buffer using a fixed time interval, and sends it to the DA (digital-to-analog) converter (video DAC) to produce the video output.It is a microcode-reprogrammable T&L GPU, composed of two integrated processors: the Reality Signal Processor (RSP) and the Reality Display Processor (RDP). GPU: 64-bit Reality Coprocessor, running at 62.5 MHz and over half a billion arithmetic operations per second, capable of dual-issuing scalar and vector operations under the right circumstances.Performance: 125 MIPS ( million instructions per second), 93.75 MFLOPS (million floating-point operations per second).The Nintendo 64 motherboard, showing CPU, RCP, and RDRAM
