2 Description

The SMJ320C6203 device is part of the SMJ320C62x

fixed-point DSP generation in the SMJ320C6000

DSP platform. The C62x DSP devices are based on

the high-performance, advanced VelociTI VLIW

architecture developed by TI, making these DSPs an

excellent choice for multichannel and multifunction

applications.

The SMJ320C62x DSP offers cost-effective solutions

to high-performance DSP-programming challenges.

The SMJ320C6203 has a performance capability of

up to 1600 MIPS at a clock rate of 200 MHz. The

C6203 DSP possesses the operational flexibility of

high-speed controllers and the numerical capability of

array processors. This processor has 32 generalpurpose

registers of 32-bit word length and eight

highly-independent functional units.

The eight functional units provide six ALUs for a high degree of parallelism and two 16-bit multipliers for a 32-bit

result. The C6203 can produce two multiply-accumulates (MACs) per cycle for a total of 400 million MACs per

second (MMACS). The C6203 DSP also has application-specific hardware logic, on-chip memory, and additional

on-chip peripherals. The C6203 device program memory consists of two blocks, with a 256KB block configured

as memory-mapped program space, and the other 128KB block user-configurable as cache or memory-mapped

program space. Data memory for the C6203 consists of two 256KB blocks of RAM.

The C6203 device has a powerful and diverse set of peripherals. The peripheral set includes three McBSPs, two

general-purpose timers, a 32-bit expansion bus that offers ease of interface to synchronous or asynchronous

industry-standard host bus protocols, and a glueless 32-bit EMIF capable of interfacing to SDRAM or SBSRAM

and asynchronous peripherals.

The C62x devices have a complete set of development tools that includes: a new C compiler, an assembly

optimizer to simplify programming and scheduling, and a Windows® debugger interface for visibility into source

code execution.
