Wolfson's Milne plans an 'active retirement'
News & Analysis 11/24/2006 Post a comment
David Milne, who has announced he will retire from all executive duties from Wolfson Microelectronics , the company he co-founded in 1984, has no intention of leaving the business world entirely, nor even the semiconductors business, he told EE Times Europe . But he said Wolfson needed someone younger at the helm to take the company to the next stage of its development, which he stressed does not mean a diffe
Media SoC design for reduced power consumption
Design How-To 11/24/2006 Post a comment
To achieve high integration and simultaneously reduce the overall system power consumption, the media SoC -- for both portables and AC powered devices -- needs to be designed with architectures that are "power conscious" which use design techniques to reduce the overall gate count and power consumption while efficiently handling data transactions to minimize inefficient, power consuming interactions with external memory.
