(Bristol, England), a vendor of event-driven processor chips, is enjoying a sales boom that will see the company move from shipping over 50,000 units a month at present to hundreds of thousands of units per month by the end of 2009, according to CEO James Foster.
Applying embedded design to develop an intelligent solar tracking system Design How-To 6/23/2009 4 comments Solar panels are typically in fixed positions. They're limited in their energy-harvesting ability because they cannot consistently take full advantage of maximum sunlight. For more effective solar energy systems, the solar panels should be able to align with sunlight as it changes during a given day and from season to season. This article examines the design advantages of creating an intelligent solar tracking system using an embedded processor and an FPGA in a system-on-a-chip (SOC) architectur
