Introduction

Embedded - DSP (Digital Signal Processors) is a branch of electronic engineering which involves transforming signals from one form to another. Digital signals process with the use of specialized embedded DSP algorithms, which are embedded in processors or other devices (e.g. FPGA, ASIC chips) to transform input signals into a useful form. The development of embedded-DSP technologies has played an important role in making many of the products we use today more efficient, intelligent, and adapted to user’s needs. In this blog we will look at the application field and working principle of the ADSP-SC587BBCZ-5B, a widely used embedded-DSP processor.

Overview of the ADSP-SC587BBCZ-5B

The ADSP-SC587BBCZ-5B is a widely used digital signal processor designed for use in embedded systems. It integrates an Arm Cortex-A5 processor with an array of computational accelerators for intensive signal processing tasks. It also offers scalability across various devices, from low-end platforms to high-end embedded systems. The ADSP-SC587BBCZ-5B supports 8-bit, 16-bit and 32-bit fixed-point data types and includes a powerful 100 MHz CoreConfig 1 core, delivering up to 400 MIPS (200 Mcycles) of performance at 166 MHz.

Application Field

Due to its array of accelerators and its powerful performance capabilities, the ADSP-SC587BBCZ-5B is most suitable for intensive signal processing applications such as image processing, voice recognition, video decoding, compression, and decoding. It is also suitable for audio, telecommunications, and networking applications. In addition, this multipurpose DSP processor can be used for applications such as digital filters, motion detection, radar and sonar systems, aerospace systems, and machine control.

Working Principle

The ADSP-SC587BBCZ-5B works on the basis of the well-known Von Neumann structure. This basic architectural principle has been widely used in computers since the mid-20th century. In this architecture, the program is stored in memory locations that can be accessed sequentially, and the data is stored in RAM and also modified. The processor reads the instructions from memory, decodes them and performs the operations on the data. This Von Neumann design enables the processor to adjust itself automatically to data and code changes without the need for reprogramming.

Conclusion

The ADSP-SC587BBCZ-5B is a powerful processor that is ideal for a wide range of embedded-DSP applications. Its array of accelerators and its Von Neumann architecture enable it to be used for a variety of tasks including image processing, voice recognition, video decoding, compression, and decoding. With its excellent flexibility and scalability, the ADSP-SC587BBCZ-5B is a great choice for embedded-DSP applications.
