104X905BA603 Main control operation panel

With the increasing demand for real-time signal processing in intelligent instruments and control systems, and the rapid development of large-scale integrated circuit technology. There is an increasingly urgent demand for a high-performance design solution to adapt to it. By combining DSP technology and ARM technology in embedded systems, the advantages of both will be fully utilized to meet the real-time and efficient communication requirements for data in intelligent control systems. This embedded system requires real-time response and strict timing. Its working environment may be very harsh, such as high temperature, low temperature, humidity, etc., so the system also requires very high stability.
Overall Design of 2 Embedded Systems
Main functions of core components
ARM and DSP respectively use Cirrus Logic’s  and TI’s TMS320VC5402. Fully utilize the rich on-chip resources of ARM and the powerful signal processing capabilities of DSP to achieve efficient and real-time signal processing and network communication functions.
is a microprocessor designed specifically for high-performance, ultra-low power products. It adopts the ARM7TDMI processor core, has 8kB high-speed buffer memory, supports memory management units, integrates LCD display controller, keyboard scanner, digital audio interface, complete JTAG and other functions on the chip, and is widely used in the embedded field. TMS320C54xDSP provides McBSPs (multi-channel buffered serial port); 6-channel DMA controller; An 8-bit enhanced HPI (host interface) that can communicate directly with external processors. Choosing such SOC (System on Chip) as the core component of the system makes it stable, reliable, and has a wide range of expandable functions.
  Overall System Design and Working Principles
The main purpose of this system is to achieve real-time signal processing and transmission, meeting the high reliability requirements of industrial sites and various measuring instruments. ARM has abundant on-chip resources and is suitable for the development of embedded systems. In this embedded system, ARM is mainly responsible for the operation, task management and coordination of the operating system, as well as the control tasks of DSP, and completes remote communication of data. Expanded external devices such as general-purpose serial ports, LCD displays, and Ethernet interfaces. Realize networking functionality by connecting Ethernet controllers. Ported Linux operating system and implemented driver programs for external hardware interfaces in ARM. DSP performs computationally intensive operations, implements various signal processing algorithms, and then communicates the processed digital signals with ARM through the host interface (HPI). ARM then transmits data to the network through an Ethernet controller, achieving remote control and monitoring.
