Low Energy, High-Power Processing
|
This week we're getting inside the workings of the next generation of chips that are set to pack a bigger computing-punch but at a fraction of the energy-expenditure of todays' models: CTO Mike Muller joins us to explain the revolutionary technology that leading microprocessor-maker ARM is developing. Also, energy-efficient world-wide computing - we find out how distributing data-processing demands around the planet can turn waste energy into useful computations, simultaneously saving CO2 emissions. Plus, in the news this week, a new malarial mosquito threat, rejection-free artificial blood vessels and the electric cap that helps users solve maths puzzle they previously found impossible.
