ABB集团位列全球500强企业（2008年在世界500强排列第256位，2009年位列第230位，2010年位列第237位），2009至2011年销售额都高达320亿美元。并在苏黎世、斯德哥尔摩和纽约证券交易所上市交易。

系统的软件设计根据硬件结构的总体划分，也可以分为两大部分来描述。整个系统的运行如图2所示，FPGA和DSP各自的程序独立运行，通过中断信号完成数据的实时交互。FPGA向DSP方向的指令是通过FPGA发送一个EDMA请求，DSP通过响应EDMA请求，建立EDMA通道，开始从FIFO中进行预处理后数据的读取，DSP向FPGA传输数据时，通过向FPGA发送一个中断信号，让其从FIFO中把压缩后的图像数据读出来。

ABB invented and manufactured many products and technologies, including the world's first three-phase transmission system, the world's first self-cooled transformer, HVDC transmission technology and the first electric industrial robot, and took the lead in putting them into commercial application. ABB has a wide range of product lines, including a full range of power transformers and distribution transformers, high-,medium-and low-voltage switchgear products, AC and DC power transmission and distribution systems, power automation systems, various measuring equipment and sensors, real-time control and optimization systems, robot software and hardware and simulation systems, high-efficiency and energy-saving motors and transmission systems, power quality, conversion and synchronization systems, and fuse and switch devices to protect the safety of power systems. These products have been widely used in industry, commerce, electricity and public utilities.

ABB Group ranks among the top 500 enterprises in the world (ranked 256th among the top 500 enterprises in 2008, 230th in 2009 and 237th in 2010), and its sales from 2009 to 2011 were as high as $32 billion. It is listed and traded on the stock exchanges of Zurich, Stockholm and new york.

According to the overall division of hardware structure, the software design of the system can also be described in two parts. The operation of the whole system is shown in Figure 2. The programs of FPGA and DSP run independently, and the real-time interaction of data is completed through interrupt signals. The instruction from FPGA to DSP is to send an EDMA request through FPGA. DSP responds to the EDMA request, establishes an EDMA channel, and starts to read the preprocessed data from FIFO. When DSP transmits data to FPGA, it sends an interrupt signal to let it read the compressed image data from FIFO.
