1. Introduction
The Fast General Purpose Input (FGPI) module is a high-bandwidth (up to 400
MBytes/sec) input data channel. The FGPI packs either four 8-bit, or two 16-bit, or
one 32-bit data sample(s) into one 32-bit word which is sent to main memory via
DMA.
The FGPI operates in two main modes: record capture or message passing

May be used as a versatile interface with streaming data sources at rates from
DC to 100MHz
May be used as a receiver port for inter-TriMedia unidirectional message passing
Allows optional synchronization with external control signals
Allows optional insertion of timestamp into message/record packet sent to
memory
Allows optional insertion of message/record length into message/record packet
sent to memory
Allows continuous data transfer using DMA transfers to two main memory buffers
