PIC32 Architecture and Programming

The Microchip PIC32 processor is a 32-bit embedded-system controller chip based on the MIPS processor, the RISC architecture treated by many textbooks on computer architecture.

Microchip provides a full set of software tools, the MPLAB integrated development environment (IDE). The mechanics of using the MPLAB IDE are described in a tutorial.
