This section describes the main features of the TMS320VC5441 digital signal processor (DSP), lists the pin assignments, and describes the function of each pin. This data manual also provides a detailed description section, electrical specifications, parameter measurement information, and mechanical data about the available packaging.
Description
The TMS320VC5441 fixed-point digital signal processor is a quad-core solution running at 532-MIPS performance. The 5441 consists of four DSP subsystems with shared program memory. Each subsystem consists of one TMS320C54x DSP core, 32K-word program/data DARAM, 64K-word data DARAM, three multichannel buffered serial ports, DMA logic, one watchdog timer, one general-purpose timer, and other miscellaneous circuitry.
