Microchip adopts MIPS for MCUs

摘要

Microchip's PIC32 family of 32-bit microcontrollers (MCUs), increase performance and add memory while maintaining pin, peripheral and development compatibility with the company's 16-bit MCU/DSC families. The PIC32 family is based on the industry-standard MIPS32 architecture - see page 6. The PIC32's MIPS32 M4K core can achieve 1.5 DMIPS/MHz operation through use of an efficient instruction-set architecture, 5-stage pipeline, hardware multiply/accumulate unit and up to 8 sets of 32 core registers. In addition, to reduce memory requirements, the PIC32 supports the MIPS16e 16 bit ISA-enabling code-size reductions of up to 40 percent. The PIC32 family is fully supported by Microchip's free MPLAB integrated development environment (IDE) which now offers unprecedented compatibility by supporting Microchip's complete portfolio of 8-, 16- and 32-bit devices.
