ANTIC |
Microprocessor dedicated to the television display. It retieves the diplay list and display data from RAM using direct memory access (DMA). It processes the higher level instructions in the display list and translates these instructions into a real-time stream of simple instructions to GTIA. |
GTIA |
A television interface chip. Converts the digital commands from ANTIC (or the 6502 directly) into the signal that goes to the television. GTIA also adds color values, player-missle graphics, and collision detection. |
POKEY |
Digital I/O chip. Handles the serial I/O bus, audio generation, keyboard scan, and random number generation. Also digitizes the resistive paddle inputs and controls maskable interrupt (IRQ) requests from peripherals. |
