Data acquisition begins with the physical phenomenon or physical property to be measured. Examples of this include temperature, gas pressure, and light intensity, and force, fluid flow, regardless of the type of physical property to be measured. Physical property converted into digital, and then by the computer for storage, processing, display or printing process, the corresponding system is called data acquisition system. With the rapid development of computer technology, data acquisition systems quickly gained popularity. A variety of products based on digital technology have been created. Digital System spread quickly; it’s mainly the following two advantages: the first is the digital processing flexible and convenient; the second is a digital system is very reliable. The main idea of Reconfigurable computing technology [1] is using the FPGA [2][3] allows the system has a dynamically configurable capacity, suitable for harsh environment applications, improve the speed of data processing. By the use of dynamic reconfigurable FPGA devices can be realized on the hardware logic function modification, application of reconfigurable computing technology can improve the speed of data processing. Data acquisition system is widely applied in many fields, and often used the abominable working environment place. The reconfigurable computing technology, can greatly improve the data acquisition system reliability and safety. The paper introduces a kind of multi-channel data acquisition system based on USB bus and FPGA, the factors affecting the performance of system are discussed, and describes how to use reconfigurable computing technology to improve the efficiency of data acquisition system while reduce energy consumption. The system in this paper uses AD's AD9220, ALTERA's EP1C6-8 and IDT's IDT70V24, Cypress’s CY7C68013.

Abstract-A cooperative management scheme for power efficient implementations of real-time operating systems on field-programmable gate-array (FPGA)-based soft processors is presented. Dedicated power management hardware peripherals are tightly coupled to a soft processor by utilizing its configurability. These hardware peripherals manage tasks and interrupts in cooperation with the soft processor, while retaining the real-time responsiveness of the operating system. More specifically, the hardware peripherals perform the following power management functionalities: 1) control the on-chip clock distribution network for driving the soft processor, its hardware peripherals, and the bus interfaces between them; 2) perform task and interrupt management responsibilities of the operating system when the soft processor is turned off; and 3) selectively wake up the soft processor and its hardware components, and put them into proper activation states based on the hardware resource requirements of the tasks under execution. The implementations of two popular real-time operating systems on a state-of-the-art FPGA device are presented. Measurements on an experimental board show that the proposed power management scheme can lead to significant power savings.Index Terms-Field-programmable gate arrays (FPGAs), operating systems, power management, soft processors.
