The TMS320C62x? DSPs (including the TMS320C6204 device) compose the fixed-point DSP generation in the TMS320C6000? DSP platform. The TMS320C6204 (C6204) device is based on the high-performance, advanced VelociTI? very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making the C6204 an excellent choice for multichannel and multifunction applications.

With performance of up to 1600 million instructions per second (MIPS) at a clock rate of 200 MHz, the C6204 offers cost-effective solutions to high-performance DSP-programming challenges. The C6204 DSP possesses the operational flexibility of high-speed controllers and the numerical capability of array processors. This processor has 32 general-purpose registers of 32-bit word length and eight highly independent functional units. The eight functional units provide six arithmetic logic units (ALUs) for a high degree of parallelism and two 16-bit multipliers for a 32-bit result. The C6204 can produce two multiply-accumulates (MACs) per cycle for a total of 400 million MACs per second (MMACS). The C6204 DSP also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals.

The C6204 includes a large bank of on-chip memory and has a powerful and diverse set of peripherals. Program memory consists of a 64K-byte block that is user-configurable as cache or memory-mapped as program space. Data memory consists of two 32K-byte blocks of RAM. The peripheral set includes two multichannel buffered serial ports (McBSPs), two general-purpose timers, a 32-bit expansion bus (XB) that offers ease of interface to synchronous or asynchronous industry-standard host bus protocols, and a glueless 32-bit external memory interface (EMIF) capable of interfacing to SDRAM or SBSRAM and asynchronous peripherals.

The C6204 has a complete set of development tools which includes: a new C compiler, an assembly optimizer to simplify programming and scheduling, and a Windows? debugger interface for visibility into source code execution.
