Modern serial buses demand sophisticated level translation News & Analysis 5/26/2004 Post a comment Electronic design has changed considerably since the days when TTL and 5V CMOS were the dominant standards for logic circuits. The increasing complexity of modern electronic systems has led to lower-voltage logic, which in turn causes incompatible input and output levels for the logic families within a system. It's not unusual, for example, that a digital section operating at 1.8V must communicate with an analog subsection operating at 3.3V. In this article from Planet Analog magazine, a Maxim e
Industry's fastest single-board computer? Product News 5/25/2004 Post a comment Board vendor General Micro Systems is rolling out what it claims is the industry's fastest CompactPCI single-board computer. Featuring a pair of hyper-threaded Pentium-4 Xeon micros, the SBC packs a six-channel video subsystem and a four-port switched-fabric hub. That lets it achieve an aggregate I/O bandwidth of a whopping 10-Gbytes/s-plus!
CompactPCI boards bolster leading-edge software-defined radio designs Product News 5/24/2004 Post a comment Wideband software-defined wireless receivers that accommodate both voice and data demand ultra-fast A/D converters and DACs, with algorithms implemented in FPGAs. Leading-edge high channel-density receivers---with their fast tuning rates and programmable bandwidths---must also accommodate multiple standards. Key is the use of a common hardware platform. Once implemented in hardware, you can then leverage growing libraries of IP cores from FPGA vendors and third-party developers. Here are two new

Agreement promises ultra-fast digitizer cores, cards Product News 5/17/2004 Post a comment RF Engines Ltd., a UK-based signal processing design house, and Swiss-based high-speed data converter supplier Acqiris are announcing details of a new high-speed digitizer design and processing core. For its part, RFEL will supply an SoC for one of Acqiris's new high-speed digitizers, a 2-Gsample/s CompactPCI card. Acqiris's card carries a Xilinx FPGA that will hold RFEL's realtime processing engine.
Motherboard marries Pentium-4 with PCI-X Product News 5/17/2004 Post a comment Board maker SuperMicro has a new motherboard that puts a Pentium-4 processor on the PCI-X high-bandwidth architecture. This product promises Internet and multimedia functions for applications ranging from gaming to graphics-intensive workstations.
Celeron M-based CompactPCI plug-in breaks $1000 barrier Product News 5/14/2004 Post a comment HHere's news of a 3U-sized CompactPCI (cPCI) single-board-computer (SBC) that delivers mid-range performance at an entry-level price. Thanks to the use of Intel's Mobile Optimized Micro Architecture, and power management, the board's Celeron M offers fast instruction execution at a reasonably low level of dissipation.
Intel-PXA255 processor board is (much) smaller than a credit card Product News 5/10/2004 Post a comment Here's a review of one tiny microprocessor board. If you're not careful, the flat cables, headers, and other interconnects and mounting hardware in a system built around one of these boards can occupy more room than the board itself! This tiny board houses a 400-MHz Intel PXA255 XScale microprocessor, making this an incredibly powerful and power-stingy multi-media-ready micro-board.
ATA/ATAPI Devices Bridge the Gap for USB 2.0 Cable-Powered Drives News & Analysis 5/10/2004 Post a comment The Universal Serial Bus (USB) has been the most successful peripheral interface in the history of PCs. USB 2.0 is capable of keeping up with the high bandwidth requirements of mass-storage peripherals. The basis for any USB 2.0 mass storage peripheral is a USB 2.0 to ATA/ATAPI bridge board. The USB 2.0 bus, however, neither communicates with nor understands ATA/ATAPI commands. A USB 2.0 to ATA/ATAPI bridge board must act as an instruction translator and data manager between the two buses.
