DSP56309 Architecture Overview
1.10.2
Host Interface (HI08)
The HI08 is a byte-wide, full-duplex, double-buffered, parallel port that can connect
directly to the data bus of a host processor. The HI08 supports a variety of buses and
connects to a number of industry-standard DSPs, microcomputers, and microprocessors
without requiring additional logic.
The DSP core treats the HI08 as a memory-mapped peripheral occupying eight 24-bit
words in data memory space. The DSP can use the HI08 as a memory-mapped
peripheral, using either standard polled or interrupt programming techniques. Separate
transmit and receive data registers are double-buffered to allow the DSP and host
processor to transfer data efficiently at high speed. Memory mapping allows DSP core
communication with the HI08 registers using standard instructions and addressing
modes.
1.10.3
Enhanced Synchronous Serial Interface (ESSI)
On the DSP56309 are two independent and identical ESSIs. Each ESSI has a full-duplex
serial port for communication with a variety of serial devices, including one or more
industry-standard codecs, other DSPs, microprocessors, and peripherals that implement
the Motorola SPI. The ESSI consists of independent transmitter and receiver sections and
a common ESSI clock generator.
The capabilities of the ESSI include the following:
¥ Independent (asynchronous) or shared (synchronous) transmit and receive
sections with separate or shared internal/external clocks and frame syncs
¥ Normal mode operation using frame sync
¥ Network mode operation with as many as 32 time slots
¥ Programmable word length (8, 12, or 16 bits)
¥ Program options for frame synchronization and clock generation
¥ One receiver and three transmitters per ESSI allows six-channel home theater
1.10.4
Serial Communications Interface (SCI)
The DSP56309Õs SCI provides a full-duplex port for serial communication with other
DSPs, microprocessors, or peripherals such as modems. The SCI interfaces without
