(1) a Fast Multichannel Analog Storage System*
A Multichannel Analog Storage System based on a commercial 32-channel parallel in/serial out (PISO) analog shift register is described. The basic unit is a single width CAMAC module containing 512 analog cells and the associated logic for data storage and subsequent readout. At sampling rates of up to 30 MHz the signals are strobed directly into the PISO. At higher rates signals are strobed int...
متن کاملdesigning a fast locking pll
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
A Multichannel Pipeline Analog-to-Digital Converter for an Integrated 3-D Ultrasound Imaging System
An 8-channel 10-bit pipeline analog-to-digital converter, designed for use in an integrated three-dimensional ultrasound imaging system, has been implemented in a 0.25m CMOS technology. Two parallel multiplexing sample-and-hold stages are employed to multiplex a total of eight adjacent ultrasound channels, each sampled at 20 MHz. The sampled and multiplexed signals are fed into two parallel tim...
متن کاملSpanFS: A Scalable File System on Fast Storage Devices
Most recent storage devices, such as NAND flash-based solid state drives (SSDs), provide low access latency and high degree of parallelism. However, conventional file systems, which are designed for slow hard disk drives, often encounter severe scalability bottlenecks in exploiting the advances of these fast storage devices on manycore architectures. To scale file systems to many cores, we prop...
متن کاملDNFStore: A Distributed Netflow Storage System Supports Fast Retrieval
Network anomaly detection or network optimization based on Netflow plays an important role in current high-speed network management. Storage and analysis of high-speed continuous Netflow are hot and difficult issues in network security research and industry communities. Existing solutions, although useful in above areas, have several drawbacks in well handling Netflow records generated by large...
