Description

Fixed-point math library (QMATH) contains highly optimized, fixed point math/trigonometric functions that are developed as an easy-to-use library, which has to be linked to the user's application. The following table summarizes the set of functions that are defined in this library.

• Documentation of Math Modules is archived in the self-extracting zip file, and the pdf files can be found in c:\tidcs\c24\dsp_tbox\math\doc directory.

• Software Test Bench (STB) support library must be downloaded to use the STB examples.
  

Software Test Bench:

To facilitate evaluation and deployment of these modules, they are made available as Software Test Benches (STBs) which run as code composer projects on readily available EVMs or eZdsp hardware platforms.

Each STB focuses on a particular software module and shows the customer how to invoke it, pass variable or data to it, and how to link it into their systems. Where possible, the module under evaluation is made to interact with other modules such as signal generators, which can provide input stimulus and data-logging modules or EVM-DAC drivers to examine a module 's response in a real-time environment. This helps customers to get a more realistic feel of the software module 's capability and applicability.

The idea behind the STB strategy to demonstrate the math function is indeed simple. Input to the math function is allowed to ramp up at incremental steps to sweep over a range of interest in a cyclic manner and the input/output of the math function are logged, sent through EVMDAC and PWMDAC for observation by the user.

Features

• "C" Callable assembly (CcA) interface & Direct ASM interface
• Each module has it’s own Software Test bench (STB) for a quick and easy "self contained" evaluation
• STB framework is offered as a Code Composer project
• Fully documented (PDF files are included within the self extracting zip file)
