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.
The 5441 also contains a host-port interface (HPI) that allows the 5441 to be viewed as a memory-mapped peripheral to a host processor.
Each subsystem has its separate program and data spaces, allowing simultaneous accesses to program instructions and data. Two read operations and one write operation can be performed in one cycle. Instructions with parallel store and application-specific instructions can fully utilize this architecture. Furthermore, data can be transferred between program and data spaces. Such parallelism supports a powerful set of arithmetic, logic, and bit-manipulation operations that can all be performed in a single machine cycle. The 5441 includes the control mechanisms to manage interrupts, repeated operations, and function calls. In addition, the 5441 has a total of 256K words of shared program memory (128K words shared by subsystems A and B, and another 128K words shared by subsystems C and D).
The 5441 is intended as a high-performance, low-cost, high-density DSP for remote data access or voice-over IP subsystems. It is designed to maintain the current modem architecture with minimal hardware and software impacts, thus maximizing reuse of existing modem technologies and development efforts.
The 5441 is offered in two temperature ranges and individual part numbers are shown below. (Please note that the industrial temperature device part numbers do not follow the typical numbering tradition.)
