The paper presents the time relations between processes and operations carried out during the registration of data from the electrical power system, stored in pendrive portable memory. The authors present and analyze the successive stages of registration of data containing information on the signals in the power system, starting from their conversion into digital form, by gathering in memory of the...
In video encoding hardware system based on camera link interface, in order to coordinate data transmission between different clock domains, we designed a DSP and FPGA interconnection scheme, in which a software FIFO was used. This article introduced relevant interface interconnects and timing analysis. The system we are using proved the method introduced in the article is stable and efficient to guarantee...
In order to meet the need to POS for high accuracy real-time motion imaging in the high resolution earth observation system, an integrated navigation computer based on FPGA and DSP was designed. FPGA independently accomplished the synchronous sampling of GPS data and IMU multichannel pulse signals; the bidirectional communication between DSP and FPGA was in the interrupt mode by EMIF; the navigation...

In this paper, the design and implementation of a frequency hopping TDMA system is presented. The system is built around software defined radio concepts. The system architecture is described in detail, which is composed of three modules. High performance digital devices of DSP and FPGA realize the IF digitalization. Software implementation for frequency hopping synchronization is discussed and a method...
A high efficiency carrier tracking loop to deals with high dynamic circumstance GPS receiver was presented in this paper. Based on FFT parallel capture method, fast frequency discrimination and its realization scheme are studied. We proposed a non-linear carrier NCO unit to track precisely by selecting interpolating filter orders. The carrier tracking is performed by the interpolating filter, which...
A photoelectric hybrid coupling current transformer has a lot of obvious advantages over a traditional electromagnetic current transformer. It is very valuable in practical application for the electricity protection and signal measurement of power system. This paper will present a complete design proposal of photoelectric coupling current transformer low voltage unit by using FPGA and DSP system....
To meet the requirement of high-speed data processing of complicated system with multi-sensor inputs and multi-controller outputs, an embedded ARM+FPGA +DSP multiprocessor platform is designed, which is characterized by synchronous cooperation and mutual exchange of shared data. ARM completes interface expansion and task scheduling configuring peripheral interfaces including RS422, CAN and RJ45, and...
In this paper we describe a methodology to do rapid hardware prototyping of a part of a digital signal processing system described in Simulink. It explains the main technical problems when trying to go to hardware from a pure functional description and the solutions proposed to solve them. The methodology is applied on a proven model, from the architecture co-simulation, to the real hardware implementation...
This paper presents a distributed control system architecture for power electronics conversion systems. Control partitioning is described and a two-level control hierarchy is proposed. Specifically, a hardware manager-controlling the actual power conversion process-, and an application manager, hardware independent Universal Controller are introduced and implemented. A detailed description of these...
