The DSP56854 is a member of the DSP56800E core-based family of digital signal controllers. This device combines the processing power of a DSP and the functionality of a microcontroller with a flexible set of peripherals on a single chip to create an extremely cost-effective solution. The DSP56854 includes peripherals that are especially useful for teledatacom devices, Internet appliances, portable devices, TAD, voice recognition, hands-free devices and general purpose applications.
The DSP56800E core is based on a Harvard-style architecture consisting of three execution units operating in parallel, allowing as many as six operations per instruction cycle. The microprocessor-style programming model and optimized instruction set allow straightforward generation of efficient, compact code for both DSP and MCU applications. The instruction set is also highly efficient for C
compilers, enabling rapid development of optimized control applications.
