Using dual port memory as interconnect Design How-To 4/26/2005 Post a comment Interconnect ICs enable data transfer between a variety of processing elements that do not have a compatible interface. They are also used to extend system bus that does not have the required fanout or sufficient bandwidth to meet the data transfer need. Popular interconnect components are dual-port buffers, SERDES, and PCI bridge chips. Without the usual circuit diagrams or waveforms, a Cypress engineer suggests how.

500-kHz 16-bit analog I/O board is low-profile PCI plug-in Product News 4/20/2005 Post a comment Here's news of a high-resolution data converter and control board that's priced at less than $700 a pop. The new plug-in is a PCI bus-compatible multi-function analog I/O board that imparts 16-bit precision to PC-based measurement, analysis, monitoring and control applications. Either commercial temperature range or industrial temp range versions can be ordered. PCI-X and PC/104 versions are available, too.
Building JPEG/Motion JPEG Into The Security Camera Design How-To 4/15/2005 Post a comment The Security & Surveillance industry is asking for higher and higher resolution images. The need for JPEG/Motion-JPEG compression is growing rapidly. Individual frame data is preferred to MPEG based algorithms because of its ease of use in reconstructing individual frame data for law
enforcement purposes. The existing infrastructure for the Security & Surveillance industry is based on CCTV standards. They are now beginning to migrate towards 10/100 Ethernet solutions. Here's how ISG created cam
Storage disk arrays pose challenges for chassis design Blog 4/11/2005 Post a comment We had heard from Teradyne's Chris Heard at DesignCon about some of the issues involved in the packaging of RAID storage cabinets. A visit from Maxtor confirmed some of the things we had been hearing: Though drives were getting smaller, they were getting packed tighter together on a rack. Heat and cable routing is becoming a problem. Here is Chris' commentary from Planet Analog magazine.
Less-than-$1500 data-acq board packs USB, 300-MHz DSP Product News 4/11/2005 Post a comment Data acquisition board maker Data Translation is now shipping a less-than-$1500 data acquisition and control board. As a 2-channel-in/2-channel-out board, it's intended for price-sensitive systems. "The E in the product designation stands for economy," says DT product manager Tim Ludy.
