Short Content: Serial ATA (SATA-Serial ATA) is Intel Representative's storage device developer development ATA-7 serial edition SATA 1.0. The goal is can apply generally based on the ATA memory in the tabletop, the migration storage device, the low end server and network memory domain [1]. in April, 2004, IDF once more carried on to the standard 1.0 edition's band widths and the physical level coupling improves greatly, and had issued enhancement standard SATA I, by the compatible SAS physics level, satisfied the ...

Short Content: Abstract: Introduced that one kind with realizes based on the ultra low power loss monolithic integrated circuit's data acquisition system's design; Elaborates this system's principle of work, the main feature, the system design, the hardware circuit and the software flow design specifically. This system take TI Corporation's 16 Flash the MSP430Fx44x series monolithic integrated circuit as a core, by the zero power loss magnetism sensitive sensor which the effect makes according to Wei Gende takes front end gathering, selects the ...

Short Content:     Capacity is big based on SRAM the structure FPGA, may duplicate operates, the application is quite widespread; But its structure is similar to SRAM, after the power failure, data missing, therefore on each time time electricity must load. At present realizes the load method usually to have two kinds: One kind is carries on the data with special-purpose Cable through the JTAG mouth to load, another kind is external and this FPGA the manufacturer necessary PROM chip. The former ...

Short Content: 1 introduction        Appears massively along with the electronic installation and in view of each kind of control system's physical demand, each kind of communication network produces one after another. As a result of theirs bus structure, the communication protocol and the transmission characteristic are various, brings for the different equipment's between connection troublesome, thus is urgently needed between each kind of main line the switching device. At present the popular scene communication network had RS-232, RS422/485, HART, Profield, ...
