The ADAU1467WBCPZ-300 is an embedded digital signal processor (DSP) made by Analog Devices which has a wide range of applications, including sophisticated audio signal processing, sample-rate conversion and video image processing, as well as 3D audio, real-time effects and finite impulse response (FIR) filters. This processor is designed for real-time programmable digital signal processing applications, with the ability to perform multiple tasks simultaneously. It is also suited for voice recognition and wireless communication.

The ADAU1467WBCPZ-300 is a single-chip DSP with the following features:

• A 32-bit core for general-purpose applications
• A 32-bit floating point core for high-speed floating-point operations
• A 37.5Mbit/s crossbar switch
• Up to 10 channels of audio input and output
• Up to 4 channels of video input and output
• Audio filters, including FIR and IIR
• High-speed audio sample rate converters
• ADPCM and multi-channel digital audio coding
• Power efficient digital video processing algorithms
• Data interfacing with USB, SPI, I2C, (UART, Ethernet) and AV interfaces.

The ADAU1467WBCPZ-300 is based on the SigmaDSP core from Analog Devices, which is widely used in audio systems for its flexibility and easy-to-use development tools. The SigmaDSP core is designed to provide a powerful and low-power DSP solution for high-performance, low-power embedded applications such as audio amplifiers and receivers, acoustic echo cancellation, speech recognition, low-power virtual reality experiences, and much more.

The working principle of the ADAU1467WBCPZ-300 is the same as other digital signal processors. It receives digital audio signals, processes them according to predetermined instructions and provides output digital audio signals. The processor’s analog-to-digital converters convert incoming analog audio into digital format. This is then processed by the SigmaDSP core, a 32-bit, floating-point processor. This processor performs multiple digital signal processing functions, such as audio filtering, equalization and compression, as well as sample rate conversion and digital-to-analog conversion. The SigmaDSP core also features a number of built-in tools such as audio mixers, delay lines and dynamic range controllers. The audio processing results are then outputted in the form of digital audio signals to a DAC or other output hardware.

The ADAU1467WBCPZ-300’s capabilities also include support for dynamic range control algorithms and built-in audio effects such as 3D and virtual surround sound. The processor is also able to process up to 10 channels of audio at a time, and has a wide range of data interfaces including USB, SPI, I2C, UART and AV.

The wide range of features offered by the ADAU1467WBCPZ-300 make it an ideal embedded DSP for many complex audio system designs. With its high-performance floating point processor, flexible audio processing capabilities and wide range of data interfaces, the ADAU1467WBCPZ-300 can be used to create sophisticated audio processing applications and products.
