Introduction

TMS320C2xx Generation
Texas Instruments uses static CMOS integrated-circuit technology to fabricate
the TMS320C2xx DSPs. The architectural design of the ’C2xx is based on that
of the ’C5x. The operational flexibility and speed of the ’C2xx and ’C5x are a
result of an advanced, modified Harvard architecture (which has separate
buses for program and data memory), a multilevel pipeline, on-chip peripher-
als, on-chip memory, and a highly specialized instruction set. The ’C2xx per-
forms up to 40 MIPS (million instructions per second).
The ’C2xx generation offers the following benefits:
-
Enhanced TMS320 architectural design for increased performance and
versatility
-
Modular architectural design for fast development of additional spin-off
devices
-
Advanced IC processing technology for increased performance
-
Fast and easy performance upgrades for ’C1x and ’C2x source code,
which is upward compatible with ’C2xx source code
-
Enhanced instruction set for faster algorithms and for optimized high-level
language operation
-
New static design techniques for minimizing power consumption
Table 1–2 provides an overview of the basic features of the ’C2xx DSPs.
