The LPC408x/7x is an Arm® Cortex®-M4 based digital signal controller for embedded applications 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 block integration. The Arm Cortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvard architecture with separate local instruction and data buses as well as a third bus for peripherals, and includes an internal prefetch unit that supports speculative branching. The Arm Cortex-M4 supports single-cycle digital signal processing and SIMD instructions. A hardware floating-point processor is integrated in the core for several versions of the part.
