Question

could you explain to me what the I^2S bus is? the importance of it (why it is necessary) or point me to some articles about it?

Answer 1

Basically ,Many of digital audio systems are being introduced into the consumer market, including compact disc, digital audio tape, and digital TV-sound. The digital audio signals in these systems are being processed by a number of (V)LSI ICs,

• digital signal processors;
• digital filters;
• digital input/output interfaces

Standardized communication structures are vital for both the equipment and the IC manufacturer, because they increase system flexibility. To this end, we have developed the inter-IC sound (I2S) bus – a serial link especially for digital audio.
