64-Bit Quad-Core Processor

Freescale Semiconductor introduces two 64-bit, multicore QorIQ™ P5 family control plane processors delivering 2.4 GHz of single threaded performance per core. The new quad-core QorIQ P5040 and dual-core P5021 products feature a robust mix of accelerators, high-speed interfaces and security features, resulting in advanced embedded solutions ideally suited for power-conscious control plane applications.The new products complement Freescale’s previously announced QorIQ P5020 and P5010 devices based on 2 GHz cores, and round out one of the industry’s most comprehensive portfolios of embedded control plane processors. With the new products, Freescale will soon offer a range of single-, dual- and quad-core 64-bit devices for a broad array of applications,...

Low Cost 100W Inverter

Here is a 100 Watt inverter circuit using minimum number of components.I think it is quite difficult to make a decent one like this with further less components.Here we use CD 4047 IC from Texas Instruments for generating the 100 Hz  pulses  and four 2N3055 transistors for driving the load. The IC1 Cd4047 wired as an astable multivibrator produces two 180 degree out of phase 100 Hz pulse trains.These pulse trains are  preamplifed by the two TIP122 transistors.The out puts of the TIP 122 transistors are amplified by four 2N 3055 transistors (two transistors for each half cycle) to drive the inverter transformer.The 220V AC will be available at the secondary of the transformer.Nothing complex just the elementary inverter principle...
