4-way superscalar DSP processor for audio codec applications

The recent audio CODEC (Coding/Decoding) algorithms are complex of several coding techniques, and can be divided into DSP tasks, controller tasks and mixed tasks. The traditional DSP processor has been designed for fast processing of DSP tasks only, but not for controller and mixed tasks. This paper presents a new architecture that achieves high throughput on both controller and mixed tasks of ...

Wireless MPEG-4 video on Texas Instruments DSP chips

Technology has advanced in recent years to the point where multimedia communicators are beginning to emerge. These communicators are low-power, portable devices that can transmit and receive multimedia data through the wireless network. Due to the high computational complexity involved and the low-power constraint in wireless applications, these devices require the use of processors that are po...

Designing Dsp Algorithm with the Virtex-4 Xtremedsp Slice

Finite impulse response (FIR) filter is the key functional block in DSP (Digital Signal Processing) designs and nearly always form the starting point for analyzing an architecture. This paper contains a new filter architecture, along with FPGAVirtex-4 (Xilinx) and XtremeDSP (DSP48) slice. The XtremeDSP slice is a high performance multiplier and arithmetic unit with great flexibility that can fo...

A Virtual Dsp Architecture for Mpeg-4 Structured Audio

The MPEG-4 Audio standard provides a toolset for synthetic Audio generation and Audio processing called Structured Audio (SA). SA permits to describe algorithms through its Structured Audio Orchestra Language (SAOL) programming language. Unlike some other languages of the same type, SAOL has a sample-by-sample execution structure, and this makes particularly important the overhead computation i...
