Embedded digital signal processors, or DSPs, are computer based systems that process digital signals such as sound and video. The ADSP-21060CW-160 is an example of a DSP system. This application field and working principle will be discussed here in greater detail.

The ADSP-21060CW-160 is a floating-point digital signal processor (DSP) optimized for embedded applications with multimedia, audio, voice and general purpose signal processing functions. It is designed to operate with 16-bit to 32-bit word lengths with clock speeds up to 160 MHz. It has a Harvard three-bus architecture with unified 16 kilobyte instruction, data and program caches and is supported by extensive development tools and programming environments.

In terms of application field, the ADSP-21060CW-160 is commonly utilized in multimedia, graphics and communication applications. This DSP system is ideal for applications that require audio, video and streaming media processing, voice recognition, speech synthesis and multi-rate signal processing. It is also well-suited for applications such as industrial automation, instrumentation, metering, environmental monitoring, and medical imaging. This DSP system is scalable, configurable and can combine with other DSPs to provide higher performance and more complex system functions. In addition, its low power consumption and small form factor makes it an attractive choice for hand-held and embedded applications.

In terms of working principle, the ADSP-21060CW-160 has a 16 kilobyte program store which holds the instructions that control its operation. These instructions are written in assembly language, which is a low-level programming language designed for efficient and fast execution. The instructions are stored in fixed-length instructions, each containing the opcode, source and destination registers and 8-bit displacement field. The displacement field is used to reference memory, input/output and other non-addressable operations. The processor has two program stores and can operate on multiple threads simultaneously, allowing for parallel execution and higher performance. The system supports a variety of data formats, including 8-bit, 16-bit and 32-bit, as well as packed and single precision floating point.

The ADSP-21060CW-160 supports a wide range of peripherals, including UART, CAN, SCI, SPI, I2C and USB. The DSP has an internal DMA controller for fast transfers of large amounts of data. It also has an internal memory controller for memory organization, access and control. The system supports 32-bit memory access with single-cycle access and 16-bit memory access with two-cycle access. In addition, the processor has an on-chip debugging capability and extensive operating system support. The operating system provides a multitasking environment with support for real-time operating systems and standard software libraries.

The ADSP-21060CW-160 is a high-performance, embedded digital signal processor with a wide range of applications. It is designed for low power consumption, configurability and scalability and is supported by development tools and robust programming environments. The processor has a Harvard architecture with unified 16 kilobyte instruction, data and program stores and has on-chip debugging capability and memory controllers. It supports a variety of data formats and a wide range of peripherals, including UART, CAN, SCI, SPI, I2C and USB. The system is ideally suited for a wide range of multimedia, graphics communications applications.
