CS47024C-CQZR

Digital Signal Processors (DSPs) are devices used to process digital signals. DSPs are widely used in a variety of embedded applications, ranging from consumer electronics such as HDTVs to industrial applications such as robot controllers. The CS47024C-CQZR is a high performance DSP from Cambridge Silicon Radio (CSR), designed to meet the requirements of demanding embedded applications. This article will discuss the application field and working principle of the CS47024C-CQZR.

Application Field

The CS47024C-CQZR is a highly integrated DSP with a wide range of features designed to meet the requirements of embedded applications. It integrates a 32-bit RISC CPU, a 16-bit A-law/μ-law codec, a memory controller and a peripherals interface into a single system-on-chip (SoC). This allows it to provide versatile functionality, including wireless audio and voice streaming, audio playback/recording, digital signal processing (DSP), communications, and embedded control.

The primary application field of the CS47024C-CQZR is wireless audio streaming. Its integrated codec and wireless connectivity enables it to support Bluetooth audio streamers, Wi-Fi audio streamers and other wireless audio streaming applications. Another application field of the CS47024C-CQZR is digital signal processing (DSP). The DSP in the CS47024C-CQZR can be used for audio signal processing and radio frequency (RF) signal processing, such as echo cancellation, noise suppression, equalization and RF attenuator control. Finally, the CS47024C-CQZR is also suitable for embedded control applications. It can be used to implement programmable logic controllers (PLCs), robot controllers and other embedded systems.

Working Principle

The CS47024C-CQZR is a highly integrated DSP with a range of onboard peripherals. The integrated 16-bit A-law/μ-law codec allows it to support voice streaming and audio playback/recording. It also has a built-in memory controller and peripherals interface to enable it to support other functions.
