NXP Semiconductors introduced the LPC1769 and LPC1759 microcontrollers that operate at 120 MHz. With 256-point 16-bit FFT execution time of less than 190 µs, this is 54% faster than the nearest Cortex-M3 alternative and challenges low-cost DSPs in performance. For 1024-point 16-bit FFT the execution time is less than 0.89 ms. These times include the FFT initialization and overhead of the algorithm. The LPC1769 and LPC1759 microcontrollers are available now with recommended distribution pricing in 10,000 quantities starting at just over $4 (US).
