The LPC408x/7x is an ARM Cortex-M4 based digital signal controller for embeddedapplications requiring a high level of integration and low power dissipation.
The ARM Cortex-M4 is a next generation core that offers system enhancements such as low power consumption, enhanced debug features, and a high level of support blockintegration. The ARM Cortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvardarchitecture with separate local instruction and data buses as well as a third bus forperipherals, and includes an internal prefetch unit that supports speculative branching.
The ARM Cortex-M4 supports single-cycle digital signal processing and SIMDinstructions. A hardware floating-point processor is integrated in the core for severalversions of the part.
