The trend toward further integration of automotive electronic control units functionality into domain control units as well as the rise of computing-intensive driver assistance systems has led to a demand for high-performance automotive computation platforms. These platforms have to fulfill stringent safety requirements. One promising approach is the use of performance computation units in combination with safety controllers in a single control unit. Such systems require adequate communication links between the computation units. While Ethernet is widely used, a high-speed serial link communication protocol supported by an Infineon AURIX safety controller appears to be a promising alternative. In this paper, a high-speed serial link IP core is presented, which enables this type of high-speed serial link communication interface for field-programmable gate array–based computing units. In our test setup, the IP core was implemented in a high-performance Xilinx Zynq UltraScale+, which communicated with an Infineon AURIX via high-speed serial link and Ethernet. The first bandwidth measurements demonstrated that high-speed serial link is an interesting candidate for inter-chip communication, resulting in bandwidths reaching up to 127 Mbit/s using stream transmissions.

Open loop shaped control system is a form of system control without any feedback from the system. One example is the on-off condition which functions to connect and disconnect electricity. The condition to be studied is a dc motor that can be set to live and die via internet server-based client service. The server in this system is a virtual private server (VPS) device that will provide a source of service to the client in the form of a collection of information on dc motor conditions. In addition, its function is also to record the working time of the dc motor. So that a schedule can be determined when the dc motor is maintained. While the client is a control unit consisting of a microcontroller device, an ethernet module enc28j60 and a dc motor. In general the working principle of the system is beginning with the user accessing the desired VPS IP address through a web browser application. From the web browser the user chooses a dc motor to be activated. But before the client has been connected to the VPS regularly (every second), the point is to always get the latest dc motor condition information. Then the microcontroller will set the dc motor in active or off condition. The research method used is research and development. The results obtained from this study are that the amount of bandwidth needed for communication between VPS and microcontrollers via the internet network, when the control unit works is 6.02 kbps, while the response time for dc motor is 3.16 seconds and the response time for dc motor 2 is 3.46 seconds.

Numerical control (NC) technology is a kind of technology combined with electronics, machinery manufacturing, and other interdisciplinary combination of technologies. It is an important part of modern manufacturing. Currently, NC technology is developing towards the open CNC system with extensibility and interchangeability, while the modern electronic technology is developing towards the programmable technology and SoC (System-on-Chip) technology. However, current CNC controller designed with SoC is still in the research stage and not practical yet. In this paper, a practical CNC motion controller is built with modern PSoC (Programmable System-on-Chip) with wireless Ethernet interface. This controller has a high-performance microprocessor, numbers of free configurable analog and digital devices and IO (input/output) interfaces, and many kinds of communication interfaces. Therefore, it has good real-time control functions and communication functions. Experiments for controlling a three joint-axis engraving machine show that the controller can achieve high performance of parallel control of the three joint-axis linear interpolation and two joint-axis circular interpolation, and high performance of the trapezoidal and S-shape speed control. In addition, in order to reduce the impact to the motor and increase the system efficiency, a kind of look-ahead algorithm for velocity control with low time cost is used.

In order to eliminate the influence of frequency change on real-time voltage acquisition, a low-cost solution of voltage monitoring was proposed using the multi-channel DMA synchronous frequency trace-sampling technique. In-chip resources of the designed voltage monitor were fully utilized in hardware design to reduce external devices. The MQX RTOS was used to perform the functional tasks flexibly and efficiently; especially the Ethernet communication applications and USB device connection were realized using its TCP/IP protocol stack and USB driver. In addition, to ensure the safety of electrical records, data statistics and alarm information management were also implemented through the management of the storage in FLASH. The test results show that the voltage monitor designed in this paper has the advantages of accurate measurement, strong resistance to frequency interference and low cost, and can be widely applied in the field of voltage monitoring in distribution networks.

In order to speed up the acquisition and processing of signal, this paper has developed a signal acquisition and processing system based on zynq platform. Based on the ARM Cortex-A9 dual-core and editable logic unit architecture of Zynq AP SoC platform, this paper implements a fully functional signal acquisition and processing system by software and hardware collaborative design. ARM0 is the main processor that controls system and shared resources. ARM1 is the slave processor. ARM1 is responsible for receiving the data converted by the AD7606 analog-to-digital chip. The data is sent to the Hamming window function IP core created under vivado HLS through the AXI bus. After the data is processed by Hamming window function, it is sent to ARM1 again through AXI bus. OCM acts as the shared memory for ARM0 and ARM1 communication. The Linux system runs on ARM0. The processed data is sent to the upper computer through ethernet through UDP protocol. Utilizing the architecture of the Zynq platform, the system efficiency is improved, and the stability of the system is ensured, so that the FPGA can enter the field of embedded systems.
