The PowerPC ᭨ 405LP system-on-a-chip (SoC) processor, which was developed for high-content, battery-powered application space, provides dynamic voltage-scaling and on-the-fly frequency-scaling capabilities that allow the system and applications to adapt to changes in their performance demands and power constraints during operation. The 405LP operates over a(More)
Commercial Cache-Coherent Non-Uniform Memory Access (ccNUMA) systems often require extensive investments in hardware design and operating system support. A different approach to building these systems is to use Standard High Volume (SHV) hardware and stock software components as building blocks and assemble them together with minimal investments in hardware(More)
A 32nm SOI critical path monitor (CPM) that can provide timing measurements to a Digital PLL for dynamic frequency adjustments in the 8-core POWER7+™ microprocessor is described. The CPM calibrates to within 2% of cycle time from nominal to turbo voltages. Its voltage sensitivity is 10mV/bit. It tracks processor temperature sensitivity to within 1.5%(More)
Recently, graphene field-effect transistors (FET) with cutoff frequencies (f(T)) between 100 and 300 GHz have been reported; however, the devices showed very weak drain current saturation, leading to an undesirably high output conductance (g(ds)= dI(ds)/dV(ds)). A crucial figure-of-merit for analog/RF transistors is the intrinsic voltage gain (g(m)/g(ds))(More)
