Microchip Technology MA240020 Data Sheet

16-bit Embedded Control Solutions

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.

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.

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 XC16 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.

The Real-Time Data Monitor 

saves development and 

testing time for embedded 

control applications. RTDM 

allows users to make 

a change to a software 

parameter and see the 

effect immediately without 

stopping the application execution. A serial USB or UART 

cable supports bi-directional data transfers between the 

host PC and the MCU/DSC.

The Data Monitor and Control Interface (DMCI) provides 

dynamic access and control of software variables. It is 

useful for tuning application parameters and viewing run-time 

application data graphically. Software parameter changes are 

updated during run-time. Feature highlights include:

   

■

MPLAB X project aware: The current device and software 

variables are recognized automatically by DMCI

   

■

Compiler independent

   

■

Debug tool independent

   

■

Provides effortless graphical analysis 

of application data

The Microchip Device Blocksets for MATLAB Simulink 

provide a set of interface-compliant configuration and run-

time peripheral blocks for the dsPIC30 and dsPIC33 DSCs.
Complete applications can be created in the form of a 

MATLAB/SIMULINK model using blocksets provided by 

Microchip and Simulink. C code for the application will be 

generated. These blocksets are compatible with the MATLAB 

plug-in available in MPLAB X IDE. Many examples in the form 

of demo models are also provided, including a complete 

BLDC motor control application.

The dsPICworks Data Analysis and DSP Software makes it 

easy to evaluate and analyze DSP algorithms. You can run 

a variety of DSP and arithmetic operations and analyze your 

data in both time and frequency domain.

The Digital Filter Design Tool makes designing and 

analyzing FIR and IIR filters easy. When the user enters 

frequency specifications, the tool automatically generates 

the filter code and coefficients. Graphical output windows 

provide the desired filter’s characteristics.
