description

The TMS320C62x DSPs (including the TMS320C6202 device) are the fixed-point DSP family in the TMS320C6000 platform. The TMS320C6202 ('C6202) device is based on the high-performance, advanced VelociTI very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making this DSP an excellent choice for multichannel and multifunction applications.

With performance of up to 2000 million instructions per second (MIPS) at a clock rate of 250 MHz, the 'C6202 offers cost-effective solutions to high-performance DSP programming challenges. The 'C6202 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 'C6202 can produce two multiply-accumulates (MACs) per cycle for a total of 500 million MACs per second (MMACS). The 'C6202 DSP also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals.

The 'C6202 includes a large bank of on-chip memory and has a powerful and diverse set of peripherals. Program memory consists of two 128K-byte blocks, with one block configured as memory-mapped program space, and the other block user-configured as cache or memory-mapped program space. Data memory consists of two 64K-byte blocks of RAM. The peripheral set includes three multichannel buffered serial ports (McBSPs), two general-purpose timers, an expansion bus (XB) that offers ease of interface to synchronous or asynchronous industry-standard host bus protocols, and a glueless external memory interface (EMIF) capable of interfacing to SDRAM or SBSRAM and asynchronous peripherals.

The 'C6202 has a complete set of development tools which includes: a new C compiler, an assembly optimizer to simplify programming and scheduling, and a Windowsdebugger interface for visibility into source code execution.
