Embedded – DSP (Digital Signal Processors)

DSP or Digital Signal Processors are application specific integrated circuits (ASICs) devoted to performing digital processing on signals. They are used to speed up digital filters, matrix operations and Fourier transforms, as well as other processes. The ADSP-2111BG-80 is one such processor, designed for embedded applications such as digital receivers, ultrasound medical imaging, digital audio and security imaging.

General Description

The ADSP-2111BG-80 is a 16-bit digital signal processor from Analog Devices and is one of the ADSP-2100 family of products. It is a powerful processor, containing 4KB of on-chip memory, 16K of program memory, 12K of data memory and 2K of buffer memory. It also contains some additional features such as a 10-bit A/D input, serial communication interface and a 32-bit external bus. This processor is suitable for audio processing, voice recognition, security imaging, digital receivers and ultrasound medical imaging, among other applications.

Application Fields

The most common applications of the ADSP-2111BG-80 are in digital receivers, ultrasound medical imaging, digital audio and security imaging. Digital receivers process digital data, such as digital video and digital audio, from an input signal, which is received from a satellite, cable or other transmission medium, and output the processed signal for further processing or display. Ultrasound medical imaging involves the monitoring and recording of soundwaves that allow doctors to make diagnoses and evaluate conditions of organs, tissues and blood vessels. Digital audio is used in a wide range of applications such as digital music players, audiobooks and digital radio.

Security imaging involves the capturing and processing of images using digital signal processing techniques. This type of application requires the use of special hardware and software solutions to capture images, which are then analyzed and analyzed using signal processing techniques. The ADSP-2111BG-80 chip is well-suited to use in these applications as it provides an integrated solution with the necessary hardware and software.

Working Principle

The ADSP-2111BG-80 chip is based on the same architecture used by other members of the ADSP-2100 family. The processor is divided into two functional units: the instruction unit and the data unit. The instruction unit is responsible for decoding instructions sent by the host processor and for executing them. The instruction unit is capable of accessing both internal and external memory, as well as communicating with external devices. The instruction unit also contains a set of dedicated registers and control signals.

The data unit is responsible for data manipulation, such as arithmetic and logic operations, and for transferring data between the instruction unit and the external device or memory. The data unit is also responsible for managing the address and data buses, as well as controlling access to memory. The instruction and data units are connected via a special bus that is used to transfer instructions and data between them.

The ADSP-2111BG-80 chip is capable of performing a variety of digital signal processing operations, such as fast Fourier transforms, calculations of derivative and integration, matrix operations, and more. Additionally, the ADSP-2111BG-80 is capable of generating pulse width modulation (PWM) and servo control signals.
