Texas Instruments TMS320VC5503

the tms320vc5503 fixed-po t digital signal processor (dsp) is based on the tms320c55x dsp generation cpu processor core. the c55x dsp architecture achieves high performance and low power through creased parallelism and total focus on reduction power dissipation. the cpu supports an ternal bus structure that is composed of one program bus three data read buses two data write buses and additional buses dedicated to peripheral and dma activity. these buses provide the ability to perform up to three data reads and two data writes a s gle cycle. parallel the dma controller can perform up to two data transfers per cycle dependent of the cpu activity. the c55x cpu provides two multiply-accumulate (mac) units each capable of 17-bit 17-bit multiplication a s gle cycle.
