Cover Story
- Programmable Audio: Part One Flexible silicon: GUI-programmable audio
processors—an EDN BenchPress project
A trend in signal-processing ICs offers simple and direct parametric control and functional programmability. Taking full advantage of flexible chips, however, may demand flexibility in your design methods, as well.
Design Features
- Testing UWB: Don't try this at home!
Ultrawideband wireless communication may be the wave of the future, but engineers who lack solid RF-test expertise will need assistance from an experienced test lab to establish UWB-product compliance with FCC specs. - ExpressCard eases power-management woes
Although the ExpressCard power-management standard is similar to PC Card technology, important design differences exist. - Architectural-design considerations for implementing hardware acceleration
Exploiting hybrid software/hardware parallelism in algorithm-hardware accelerations can yield significant performance gains over a function-replacement approach. - PCI Express and USB 2.0 improve performance of PC-based measurements
Advances in PC and silicon technologies allow low-cost, PC-based plug-in devices to accurately and quickly perform measurements and control.
