Introduction
SADF Engine Libraries it is a set of libraries for SADF Engine that could be used in DSP applicatoins. There are two type of SADF Engine Libraries:
- Common Libraries (floating or fixed point arithmetic)
- Platform Specific Libraries
- DSP Specific Libraries
SADF Common Libraries are libraries that are common for all platforms that are supported by SADF and Star-SysSolutions.com. Common libraries provided together wwith SADF Engine for specific platform. Project that based only on common libraries could be executed on any supported platform without modifications.
Common libraries includes main DSP functionality:
- Real
- Complex
- Logix (fixed point)
- Debug
SADF platform specific libraries include hardware related functionality like registers, I/O, DMA etc... These libraries strongli depends on a platform.
DSP Specific Libraries are libraries that inplemens some specific DSP functionality for specific platforms, like some high optimazed codecs, etc.
SADF Engine Common Libraries
SADF Engine Common Libraries it is collection of precompiled firmware and software components that realise common DSP functionality.
SADF Engine Common Libraries includes main DSP functionality:
- Real
- Complex
- Logix (fixed point)
- Debug
Blocks from these libraries will work on every supported platform.
