The most important stage in MP3 audio processing is Sub-band code/decode, which takes much computational load. In this paper, a solution with configurable processor based on TTA(Transport Trigger Architecture) was proposed to meet with real-time decoding system. According to the algorithm of Subband Synthesis Filter and requirement of accuracy, all the features was custom, such as bus number, bus...
A hardware design of a configurable and extensible processor named Tcore, which is based on transport triggered architecture (TTA), is presented in this paper. Due to its flexibility, the Tcore can be used as an application specific processor, especially as a coprocessor for different DSP applications. We have configured Tcore to an instruction level parallel processor to support the application of...
Transport triggered architecture (TTA) is one kind of application-specific instruction processors (ASIP), which fits embedded systems and offers a cost-effective trade-off between the energy-efficiency and performance. However its architecture and very long instruction word (VLIW) are alike, which also results in a very poor code density. In embedded systems, memory is one of the most expensive resources...
