The PowerFoot, equipped with three internal microprocessors and 12 sensors that measure force, inertia and position, automatically adjusts its angle, stiffness and damping 500 times a second.
This work eventually use the Cyclone II family EP2C70F672C8N chip as the main chip to achieve, relative to other design which uses such as DSP and ARM microprocessor, internal control circuit is simple and reliable, and has more power and cost advantages.
However, the high complexity and the low observability of microprocessors' internal resources make the identification of adequate on-line error detection strategies a very challenging task, which can be tackled at circuit or system level.
In the 21st century green technologies will provide new drivers for economic growth as the internal combustion engine and microprocessor did in the last.
The wispy-thin internal leads that connect a microprocessor's transistors are beginning to interfere with one another like crossed lines in a busy telephone exchange.
Mr. Meadlock said the disputed patents relate to technology used to keep the microprocessor's own internal memory, known as its cache, synchronized with a computer's main memory, or RAM.
IN FOCUS -- Like all image stabilization binoculars, the Canon 10X30 ($640) tracks the movements of the user's hands and then uses microprocessors and moving internal optical elements to offset any shakes or jerks.
Bob O'Donnell, an analyst at IDC, a market research company, said the new Intel-based Macs would for the first time let customers compare Macs with PC's directly, since the microprocessors and other internal parts would be the same.
Windows 3.0 will be able to run on machines with a minimum of 1 megabyte, or one million characters, of internal memory and an Intel 80286 microprocessor, the chip used in I.B.M. PC-AT level machines.
