Introduction

This section describes the main features of the TMS320VC5416, lists the pin assignments, and describes the function of each pin. This data manual also provides a detailed description section, electrical specifications, parameter measurement information, and mechanical data about the available packaging.

Description

The TMS320VC5416 fixed-point, digital signal processor DSP hereafter referred to as the device unless otherwise specified is based on an advanced modified Harvard architecture that has one program memory bus and three data memory buses. This processor provides an arithmetic logic unit ALU with a high degree of parallelism, application-specific hardware logic, on-chip memory, and additional on-chip peripherals. The basis of the operational flexibility and speed of this DSP is a highly specialized instruction set.
