A brief discussion on SSI interface technology and its application in audio processing[Copy link]
With the widespread application of embedded systems, the demand for serial communication within the system is getting higher and higher, and the protocols for serial data transmission are also diversified. Commonly used protocols include SSI, SPI, I2C, UART, etc. SSI (Server Side Include), commonly known as server-side embedding, is a server-based web page production technology similar to ASP. Most (especially Unix-based) WEB servers such as Netscape Enterprise Server support SSI commands. In addition, in the field of computer hardware, SSI is the abbreviation of Synchronous Serial Interface. In addition to being used for general serial data transmission, the SSI interface in the microprocessor MCF5329 can be used for synchronization of left and right channel data due to its frame synchronization signal. It supports two audio bus interfaces (I2S and AC97 interfaces). The microprocessor is a central processing unit composed of one or a few large-scale integrated circuits. These circuits perform the functions of control components and arithmetic logic components. Compared with traditional central processing units, microprocessors have the advantages of small size, light weight and easy modularization. The basic components of a microprocessor are: register stack, arithmetic unit, timing control circuit, and data and address bus. The microprocessor can complete operations such as fetching instructions, executing instructions, and exchanging information with external memory and logic components. It is the calculation and control part of the microcomputer. It can form a microcomputer with memory and peripheral circuit chips. TLV320DAC23 is a high-performance stereo high-end codec chip launched by TI. It supports multiple sampling rates and multiple audio formats, and has the characteristics of low power consumption and small package. It is widely used in portable digital audio processing systems. 1 Working principle of synchronous serial interface SSI
