HOST INTERFACE (HDI08)

8.1

INTRODUCTION

The host interface (HDI08) is a byte-wide, full-duplex, double-buffered, parallel port that can
be connected directly to the data bus of a host processor. The HDI08 supports a variety of
buses and provides glueless connection with a number of industry standard microcomputers,
microprocessors, DSPs and DMA hardware.

The host bus can operate asynchronously to the DSP core clock, therefore the HDI08 registers
are divided into 2 banks. The host register bank is accessible to the external host and the DSP
register bank is accessible to the DSP core.

The HDI08 supports three classes of interfaces:

•

Host processor/Microcontroller (MCU) connection interface

•

DMA controller interface

•

General purpose I/O (GPIO) port
