    ECESATUSB1 This Expresscard Power Esata Port Controller Card

    1 Port ExpressCard Power eSATA Controller Adapter Card StarTech ID: ECESATUSB1 This ExpressCard Power eSATA port controller card can be installed in an available ExpressCard 34/54 mm slot to provide a powered eSATA connection, and also alternatively provide either external SATA (data only) or USB 2.0 connectivity from one uniquely designed port if using with standard eSATA or USB devices. An ideal solution for using an eSATA SSD Flash drive on your laptop, the power eSATA card delivers both a high speed eSATA connection and power from the combined USB port. A versatile connectivity solution, the card features built-in port multiplier support, allowing multi-drive eSATA storage enclosures to be connected to the host computer using a single eSATA cable. Taking advantage of the transfer speed of eSATA connection and the 5V power output of the USB 2.0 port, the ExpressCard Power eSATA adapter is the perfect answer for connecting compatible mobile drive enclosures, similar to the built-in power eSATA port provided by the following laptop computers: Toshiba: Satellite E105, A350, Satellite Pro P300; Qosmio G50, X305, Portege A600, M750, R500, R600; and Tecra M10, R10, A10.

    cifX PC cards for Real-Time Ethernet and Fieldbus All major industrial protocols All common PC card formats One hardware for all Real-Time Ethernet protocols Master and Slave Wide range of device drivers Same application interface for all networks PC cards in all formats for all protocols The cifX PC card family is the unified standard supporting all Real-Time Ethernet and Fieldbus systems for PC based automation. The protocol stack is executed autonomously on the PC card and process data exchange with the host is done via Dual-Port-Memory or DMA (Direct Memory Access). Thanks to the common Hilscher Platform Strategy all PC cards use the same driver and tools - independent of protocol and card format. A change of communication protocol is done by just loading a different firmware. A rotary switch delivers an easy and reliable slot assignment for the PCI- and PCI Express card types. In addition special types e.g. with integrated NVRAM, 2-channel cards or detached network interface are available. A complete software package is always included in the scope of delivery. This package consists of one FDT-based configuration tool (IEC standard) for all products and networks, loadable firmware, documentation and a driver tool-kit. Due to own network controller netX a 10-year guarantee of delivery is granted. Spectra GmbH & Co.

The addition of PCIe x16 Gen5 to the Kodiak analyzer and SI-Fi™ interposer family brings previously unavailable analysis capabilities and efficiencies to computing, datacenter, networking, storage, AI, and other PCIe x16 Gen5 applications. With SerialTek’s proven calibration-free SI-Fi interposer technology, the Kodiak’s innovative state-of-the-art design, and the new BusXpert analyzer software, users can more easily set up the analyzer hardware, more accurately probe PCIe signals, and more efficiently analyze traces. Kodiak PCIe x16 Gen5 Analysis System At the core of the Kodiak PCIe x16 analyzer is an embedded hardware architecture that delivers substantial and unparalleled advancements in capture, search, and processing acceleration. Interface responsiveness is markedly advanced, searches involving massive amounts of data are fast, and hardware filtering is flexible and powerful. “Once installed in a customer test environment the Kodiak’s features and benefits are immediately obvious,” said Paul Mutschler, CEO of SerialTek.

  • Input/Output

    Input/Output

    Lectures 24: Input/Output I. External devices A. External devices are not connected directly to the system bus because they have a wide range of control logics, as well as data transfer speeds and formats. B. Virtually all external devices have buffers, control signals, status signals, and data bits. C. Those that deal with other forms of energy have transducers that converts from non-electrical data to electrical data, (e.g. key press to ASCII in a keyboard), or electrical data to non-electrical data (e.g. bytes to light in a monitor). D. In the past, intra-system (less than 1 meter) connections were usually parallel, and inter-system were serial. Now almost all are serial. 1. To convert from parallel to serial use a shift register. 2. USB (universal serial bus) is a common standard for serial transmission with USB 3.0 transferring at 5Gb/s. II. I/O Modules (south bridge and north bridge on a PC) on the motherboard provide the logic, buffers, error detection, and ports to communicate with the external devices on one side, and a system-type bus on the other. For external device interfaces, the modules have data, status, and control lines. For the system bus they have data, address, and control lines. The south bridge handles slower I/O devices and is connected to the north bridge rather than the system bus directly. III. Programmed I/O A. Overview of Programmed I/O waits for the processor to query it. B. Four types of I/O commands: 1) control (e.g.

It describes computers with multiple processing elements that perform the same operation on multiple data simultaneously. Thus, such machines exploit data level parallelism. History The first use of SIMD instructions was in vector supercomputers of the early 1970s such as the CDC Star-100 and the Texas Instruments ASC, which could operate on a vector of data with a single instruction. Vector processing was especially popularized by Cray in the 1970s and 1980s. Vector-processing architectures are now considered separate from SIMD machines, based on the fact that vector machines processed the vectors one word at a time through pipelined processors (though still based on a single instruction), whereas modern SIMD machines process all elements of the vector simultaneously.[1] The first era of modern SIMD machines was characterized by massively parallel processing-style supercomputers such as the Thinking Machines CM-1 and CM-2. These machines had many limited-functionality processors that would work in parallel.
