Adding VT1.5 Switching to Sonet/SDH Platforms Design How-To 12/13/2002 1 comment To support Ethernet, POS, T1s, and more, metro system designers must build equipment that can switch down to the VT1.5 level. Here's a look at some of the features to consider when building a VT1.5 switching card.
Taking the Frustration Out of Embedded Design News & Analysis 12/11/2002 Post a comment Effective hardware/software co-design tools remain elusive for most embedded-system designers. Xilinx's Rich Sevcik discusses why he thinks emerging FPGA design platforms offer a viable alternative to ASIC-based embedded design.
Tandem RF software programs streamline the design of power amplifiers News & Analysis 12/10/2002 Post a comment Harmonic-balance simulators - used in tandem with synthesis software that builds impedance matching networks -- can speed the design of RF power amplifiers. Engineers at Aerial Facilities in the UK show the steps they took to build a tunable 23-dB LDMOS amplifier with a center frequency in the 400-MHz range.
Optical Network Unit for ATM-Based Passive Optical Networks Design How-To 12/10/2002 Post a comment Among the different technologies proposed to solve the existing bottleneck in access networks, fiber-optic transmission has a special importance. Passive Optical Networks (PONs) appear to be among the more attractive architectures to be used in an Optical Access Network (OAN). Cristina Romero and associates present the main guidelines for the design of the Optical Network Unit (ONU) to be installed at the customer premises as required by this type of Fiber To The Home (FTTH) network.
Wireless SDR: overcoming next gen handset challenges Design How-To 12/9/2002 Post a comment The technologies necessary to realize true broadband wireless handsets and systems present unique design challenges. Wireless handset manufacturers are must deliver products that offer expanded services and operate transparently worldwide.
Software Is Key to Choosing Dual- or Single-Processor SoCs News & Analysis 12/4/2002 Post a comment One core or two? The choice between using single or multiple processing cores (usually DSP and RISC) in an SoC is not always an easy one. Jack Shandle discusses the issues you need to consider up front and the impact of software on the ultimate dual-core/single-core decision.
InfiniBand Networks for Enterprise Computing Design How-To 12/3/2002 Post a comment InfiniBand networks are emerging as an important technology for server clustering and may form the infrastructure for next-generation enterprise-computing systems. IBM's Dr. Casimer DeCusatis describes how InfiniBand can be used in this environment, including experimental results of a testbed using clustered servers, storage, and peripheral devices.
A Book For All Reasons Bernard Cole1 Comment Robert Oshana's recent book "Software Engineering for Embedded Systems (Newnes/Elsevier)," written and edited with Mark Kraeling, is a 'book for all reasons.' At almost 1,200 pages, it ...
