PIC32MX3XX/4XX
2.2 Architecture Overview
The PIC32MX3XX/4XX Family core contains several
logic blocks working together in parallel, providing an
efficient high performance computing engine. The
following blocks are included with the core:
• Execution Unit
• Multiply/Divide Unit (MDU)
• System Control Coprocessor (CP0)
• Fixed Mapping Translation (FMT)
• Dual Internal Bus interfaces
• Power Management
• MIPS16e Support
• Enhanced JTAG (EJTAG) Controller
