Analog Devices Inc. Processador Digital de Audio SigmaDSP ADAU1452
Processador ADI ADAU1452 SigmaDSP Áudio Digital é de qualidade automotiva e excede em muito as capacidades de processamento de sinais digitais dos dispositivos SigmaDSP® anteriores. Sua arquitetura de hardware reestruturada é otimizada para eficiência em processamento de áudio. Os algoritmos de processamento de áudio são realizados em paradigmas amostra-a-amostra e bloco-por-bloco, que podem ser executados simultaneamente em um fluxo de processamento de sinal criado com a ferramenta de programação gráfica SigmaStudio™. A nova arquitetura do núcleo processador digital de sinal (DSP) permite que alguns tipos de algoritmos de processamento de áudio possam ser executados usando significativamente menos instruções do que era exigido em gerações anteriores da SigmaDSP, levando a uma eficiência de código muito melhorada.
The audio processing algorithms are realized in sample-by-sample and block-by-block paradigms, which can both be executed simultaneously in a signal processing flow created using the graphical programming tool, SigmaStudio™. The new digital signal processor (DSP) core architecture enables some types of audio processing algorithms to be executed using significantly fewer instructions than were required on previous SigmaDSP generations, leading to vastly improved code efficiency.
