About This Manual

This guide describes the host port interface (HPI) on the TMS320C6457 digital signal processors (DSPs). The HPI enables an external host processor (host) to directly access the internal or external memory of the DSP using a 16-bit (HPI16) or 32-bit (HPI32) interface.

Notational Conventions

This document uses the following conventions.

•Hexadecimal numbers are shown with the suffix h. For example, the following number is 40 hexadecimal (decimal 64): 40h.

•Registers in this document are shown in figures and described in tables.

–Each register figure shows a rectangle divided into fields that represent the fields of the register. Each field is labeled with its bit name, its beginning and ending bit numbers above, and its read/write properties below. A legend explains the notation used for the properties.

–Reserved bits in a register figure designate a bit that is used for future device expansion.
