Popular C Compilers

MPLAB C Compilers

Microchip’s MPLAB C compilers are full-featured, ANSI

compliant high-performance tools tightly integrated

with MPLAB IDE. Source level debugging allows single

stepping through C source code and inspecting variables

and structures at critical points in the code. Integration

with MPLAB IDE means there is a single, consistent

environment to write code and to debug with the free

MPLAB SIM simulator or with MPLAB in-circuit debuggers

and emulators.

Code can be programmed into the target using

the hardware debuggers or with Microchip’s device

programmers. Compiler switches and linker customizations

are done within MPLAB IDE to provide a full graphical

front end to these powerful compilers. Editing errors and

breakpoints instantly switch to the corresponding lines in

source code. Watch windows show data structures with

defined data types, including floating point.

MPLAB C Compiler for PIC24 MCUs and

dsPIC DSCs

The MPLAB C Compiler for PIC24 MCUs and dsPIC DSCs

includes a complete ANSI C standard library, including

string manipulation, dynamic memory allocation, data

conversion, timekeeping and math libraries. The MPLAB

C Compiler has a powerful code optimizer; other 16-bit

MCUs generate as much as 165 percent larger code for

the same application.

World Class Development Tools

Math Libraries

dsPIC DSP Library

The dsPIC DSP Library provides a set of speed optimized

functions for the most common digital signal processing

applications. In total, 49 functions are supported by

the DSP Library. It is part of the 16-bit Language Tools

Libraries. The DSP Library provides significant performance

savings over equivalent functions coded in “C” and allows

developers to dramatically shorten their development time.

The functions are callable from both ‘C’ and Assembly.

Fixed Point Math Library for PIC24 MCUs and

dsPIC DSCs

The I/Q Fixed Point Math Library provides a set of speed

optimized functions for the most common digital signal

processing applications. This library provides significant

performance savings over equivalent functions coded

in C and allows developers to dramatically shorten

their development time. The I/Q math library includes

over 65 general-purpose functions composed of 28

functions supporting Q15 math and thirty seven functions

supporting Q16 math. The IQ math functions are callable

from both ‘C’ and Assembly.

Floating Point Math Library for PIC24 MCUs and

dsPIC DSCs

The IEEE-754 Compliant Floating Point Math Library is the

compiled version of the math library that is distributed with

the highly optimized, ANSI-compliant MPLAB C Compiler. It

contains advanced single and double-precision floating-point

arithmetic and trigonometric functions from the standard

C header file <math.h>. The library delivers small program

code size and data size, reduced cycles and high accuracy.
