In view of the large and high real-time data transmission in the current strapdown INS, USB interface was integrated into the strapdown INS, and a strapdown inertial navigation real-time data processing system composed of the DSP, FPGA and the USB interface was designed. The system composition and working principle were described; the overall hardware design and software design of the system were...
In this paper, a color image fusion system based on DSP and FPGA is introduced. In the system, TMS320DM642 is used as the kernel processor to finish the image's fusion arithmetic, storage and display. FPGA, which has the ability to control the logic of image capturing, is used as the assistive processor. The experiment shows that this technology can obtain color fusion image.
A robot vision system is developed based on an intelligent image gathering card that contains an FPGA (Field Programmable Gate Array) and a DSP (Digital Signal Processor) as main calculators. Two real-time visual modules are developed through the cooperation of hardware logics on FPGA and software on DSP. First, with edge images extracted by the FPGA, a highly efficient algorithm is designed to extract...
Xilinx and Mathworks jointly proposed System Generator (SysGen) and Simulink to accelerate development of DSP (digital signal processing) style applications on Field Programmable Gate Array (FPGA) chips. However, most of developments with Simulink and SysGen end at simulation stage without complete stand-alone implementation on FPGA since these tools do not come up with sufficient IO system libraries...
To meet the complex requirements of the miniature embedded integrated (INS/GPS) navigation system based on DSP, all peripheral circuits were integrated in single chip of FPGA, such as logic control module, serial/parallel data conversion and FIFO(First In First Out), etc. The multi-channel UART(Universal Asynchronous Receiver Transmitter) consists of the data conversion circuit and FIFO. In addition,...
Most existing approaches to targeting high-level software to FPGAs are based on extensions to C and do not map easily to the features and characteristics of modern FPGAs. These include massive parallelism and a variety of complex IP-blocks (eg. RAMs, DSPs). In this paper we discuss a hardware implementation of SR, a software language with first class concurrency and high-level IPC.We show that the...
In the design of control system of cascaded high voltage inverters, as the limitation of DSP's resources, introduce FPGA into the design of controls of high voltage inverters. This paper design and realize the phase-shifted pulse-generator basing on FPGA, the pulse-generator receives the duty cycle from DSP computed by carrier phase-shifting space vector PWM algorithm, which compared with multi-channel...
In view of domestic traffic, the traffic flow is increasing rapidly recent years, whereas the traffic control is deficient. This paper presents a design of intelligent traffic control system based on DSP and Nios II. Using dual-CPU, intelligent traffic control system combined with logic control in FPGA implements kinds of functions, which include cross-phase adjustment, exchanging and establishing...
License plate recognition (LPR) is an important part of intelligent transportation management (ITM). All of the information of the vehicle can be acquired by recognizing the license plate which is unique to the owner. This paper proposed an embedded system which is used to charge the toll on freeway with no parking. This system is significant to the ITM. The system includes multiple processors such...
Because of its high performance, brushless DC motors are widely used in motor vehicles. In this paper, according to analysis of present motor control system, a novel hardware structure of motor control system was presented. It is based on Field Programmable Gate Arrays (FPGA) and Digital Signal Processor (DSP). According to the function needed in motor control and the structure feature of FPGA and...
Onboard Reconfigurable Processing Platform (ORPP), which mainly consists of reconfigurable devices (FPGAs) and auxiliary co-processors such as DSPs, is dedicated to in-situ real-time computing for various space missions. Harsh ionizing radiation effects have been observed during flight thus make it crucial to design fault tolerance in ORPPs. Transient available refers to ORPP can mask transient faults...
