The TMS320C4x generation of floating-point digital signal processors is ideal for today's growing computation-intensive parallel-processing applications. With up to six on-chip communication ports and support for shared global memory on two external busses, designers can have direct processor-to-processor communication for unprecedented computation power and design flexibility.
The newest member of the 'C4x generation, the TMS320C44, is a lower cost parallel processing DSP. The 'C44 is completely compatible with the TMS320C40, has an address reach of 32 Mwords and features a low power mode that dramatically cuts power consumption. The lower cost, surface mount 'C44 device will enable high volume parallel processing applications that are more cost and power sensitive.
