MPLAB C30 C Compiler/Linker/

Librarian

The Microchip Technology MPLAB C30 C Compiler

provides ‘C’ language support for the dsPIC33F family.

This C compiler is a fully ANSI-compliant product with

standard libraries. It is highly optimized for the

dsPIC33F family and takes advantage of many

dsPIC33F architecture-specific features to help you

generate very efficient software code. Figure 10-3

illustrates the code size efficiency relative to several

competitors.

MPLAB C30 also provides extensions that allow for

excellent support of the hardware, such as interrupts

and peripherals. It is fully integrated with MPLAB IDE

for high-level source debugging.

The MPLAB C30 has these characteristics:

• 16-bit native data types

• Efficient use of register-based, 3-operand

instructions

• Complex addressing modes

• Efficient multi-bit shift operations

• Efficient signed/unsigned comparisons

MPLAB C30 comes complete with its own assembler,

linker and librarian. These allow Mixed mode ‘C’ and

assembly programs and link the resulting object files

into a single executable file. The compiler is sold

separately. The assembler, linker and librarian are

available for free with MPLAB C30.

MPLAB C30 also includes the Math Library, Peripheral

Library, DSP Library and standard ‘C’ libraries.
