A Computer-On-Module, or COM, is a Module with all components necessary for a bootable host computer, packaged as a super component. A COM requires a Carrier Board to bring out I/O and to power up. COMs are used to build single board computer solutions and offer OEMs fast time-to-market with reduced development cost. Like integrated circuits, they provide OEMs with significant freedom in meeting form-fit-function requirements. For all these reasons the COM methodology has gained much popularity with OEMs in the embedded industry. COM Express® is an open industry standard for Computer-On-Modules. It is designed to be future proof and to provide a smooth transition path from legacy parallel interfaces to LVDS (Low Voltage Differential Signaling) interfaces. These include the PCI bus and parallel ATA on the one hand and PCI Express and Serial ATA on the other hand.
Express Mode uses an 8-bit wide bus path for fast configuration of Xilinx FPGAs. Thisapplication note provides information on how to perform Express configuration specifically forthe Spartan™-XL family. The Express mode signals and their associated timing are defined.The steps of Express configuration are described in detail, followed by detailed instructions thatshow how to implement the configuration circui
SL811開發(fā)資料_包含源程序_電路圖_芯片資料:SL811HS Embedded USB Host/Slave Controller.The SL811HS is an Embedded USB Host/Slave Controller capable of communicate with either full-speed or low-speed USB peripherals. The SL811HS can interface to devices such as microprocessors, microcontrollers, DSPs, or directly to a variety of buses such as ISA, PCMCIA, and others. The SL811HS USB Host Controller conforms to USB Specification 1.1.The SL811HS USB Host/Slave Controller incorporates USB Serial Interface functionality along with internal full-/low-speed transceivers.The SL811HS supports and operates in USB full-speed mode at 12 Mbps, or at low-speed 1.5-Mbps mode.The SL811HS data port and microprocessor interface provide an 8-bit data path I/O or DMA bidirectional, with interrupt support to allow easy interface to standard microprocessors or microcontrollers such as Motorola or Intel CPUs and many others. Internally,the SL811HS contains a 256-byte RAM data buffer which is used for control registers and data buffer.The available package types offered are a 28-pin PLCC (SL811HS) and a 48-pin TQFP package (SL811HST-AC). Both packages operate at 3.3 VDC. The I/O interface logic is 5V-tolerant.
基于matlab的mp3的讀寫函數(shù)Mp3 toolbox for Matlab. Alfredo Fernandez Franco Aalborg University Departament of Acoustics M.Sc. Student aberserk@yahoo.com Includes 2 functions to write and read MP3 files. It works like the commands WAVWRITE and WAVREAD. 1.- Just unpack in the toolbox folder under the MATLAB directory. 2.- Set the MATLAB search path to include that folder. This version was made in MATLAB for WINDOWS only. I ll probably will make the UNIX version later. 01-11-2004.
AFD - Advanced Filter Design using MATLABMiroslav D. Lutovac, Dejan V. Tosicversion 1.00 released 15 October 1999This program is freeware.Unpack with path names, for exampleDOS: pkunzip -d afdunix: unzip -L afdAfter unpacking afd.zip, and run MATLAB,change directory to afdfrom the MATLAB command window.Execute demoafd to quickly scan the AFD operation.
