Audio Signal Processing: Applications
built 654 days ago
The PNX1702 contains a high-performance 32-bit VLIW processor, the TriMedia TM5250, capable of multi-standard digital video decoding/encoding and image improvement, audio signal processing, and general-purpose control processing. It can either be used in standalone implementations or as an accelerator to a general-purpose processor. The PNX1702 processes input signals by utilizing several audio/video and co-processor modules before sending them to external peripherals. These modules provide additional video and data processing bandwidth without using CPU cycles. The combination of the CPU and co-processor modules makes the PNX1702 suitable for a wide range of digital entertainment applications, especially those requiring a high level of processing power and throughput at a reduced cost.

Digital signal processing is often implemented using specialised micro processors such as the MC56000 and the TMS320. These often process data using fixed-point arithmetic, although some versions are available which use floating point arithmetic and are more powerful. For faster applications FPGAs might be used. Beginning in 2007, multicore implementations of DSPs have started to emerge from companies including Freescale and startup Stream Processors, Inc. For faster applications with vast usage, ASICs might be designed specifically. For slow applications such as flame scanning, a traditional slower processor such as a microcontroller can cope.

Mitov Software offers Delphi, C++ Builder, Visual C++ MFC/Win32 and .NET 2.0/3.0 (C#, Visual Basic, C++/CLI, J#) component libraries for Video, Audio, Signal processing, and Computer Vision. All the libraries are fully multithreaded and optimized using Intel MMX technologies. The libraries are based on the advanced OpenWire technology, and allow writing complex applications with zero or near zero lines of code

Sonic Flow is a set of C++ libraries and C wrappers for dataflow-inspired audio signal processing. Sonic Flow consists of a feature-rich synchronous dataflow (SDF) library, a set of elementary signal processing blocks and a set of ready-made example applications. The examples illustrate implementing high-quality digital effects utilizing the SDF dataflow library and the signal processing blocks.

The algorithms required for DSP are sometimes performed using specialized computers, which make use of specialized microprocessors called digital signal processors (... abbreviated DSP). These process signals in real time and are generally purpose-designed application-specific integrated circuits (ASICs). When flexibility and rapid development are more important than unit costs at high volume, DSP algorithms may also be implemented using field-programmable gate arrays (FPGAs).
