The LPC3000 series ARM chips designed by NXP Semiconductors are suitable for embedded applications that require a combination of high performance and low power consumption. NXP achieved the performance goals of the LPC3000 by combining an ARM926EJ-S CPU core with a vector floating-point coprocessor and a range of standard peripherals including USB On-The-Go using 90-nanometer process technology. The LPC3000 series ARM can operate at CPU frequencies above 266MHz. The ARM926EJ-S CPU core adds 5-stage pipeline processing and adopts Harvard architecture. The core also has a complete memory management unit (MMU) to provide virtual memory functions required to support multi-programming of modern operating systems. The ARM926EJ-S CPU core also includes a series of DSP instruction extensions with single-cycle MAC operations, as well as Jazelle Java byte code execution. The device implemented by NXP has a 32kB instruction cache and 32kB data cache.
