数字信号处理器(DSP)的出现和发展,不但给传统的模拟应用领域带来了革命,而且使通用的数据处理设备(如PC机)和家电(如音响、电话)具有了新的功能。在这场革命中,美国AD公司举起了“信号计算”的旗帜,凭籍在信号处理领域里30年的经验,AD公司不仅试图成为DSP芯片的霸主,而且有意为电子产品的原始生产制造厂家们(OEM)提供一整套硬件和软件的解决方案,并将通信和多媒体功能溶进其下一代产品。 “信号计算”是一个开放的结构,它由一个多功能的芯片集(Chipset)构成的硬件平台和相应的应用软件组成。以DSP芯片为核心加上不同的混合信号接口芯片(如声音接口芯片、公共交换
The advent and development of digital signal processors (DSPs) not only revolutionized traditional analogue applications, but also brought new capabilities to common data processing devices such as PCs and appliances such as audio and telephones. In this revolution, the United States AD company raised the “signal computing” banner, by virtue of signal processing in the field of 30 years of experience, AD company not only tried to become the dominant DSP chip, and intended for the original production of electronic products Manufacturers (OEMs) offer a complete suite of hardware and software solutions that incorporate communications and multimedia capabilities into their next generation of products. Signal Computation is an open architecture consisting of a multi-functional chipset hardware platform and corresponding application software. DSP chip as the core with different mixed-signal interface chip (such as voice interface chip, public switched
