1. Introduction
The Fast General Purpose Output (FGPO) module is a high-bandwidth (up to 400
MBytes/sec) output data channel. The FGPO outputs data in 8, 16, and 32-bit widths.
The FGPO operates in two main modes: record output or message passing
• May be used as a versatile interface with streaming data receivers at rates from
DC to 100 MHz
• May be used as a transmitter port for inter-TriMedia unidirectional message
passing
• Allows optional synchronization with external control signals
• Allows optional generation of external control signals
• Allows optional output at selected timestamp times
• Allows optional output of variable message/record lengths
• Allows continuous data output transfers using DMA transfers from two main
memory buffers
