Coherency, Cache And Configurability

Coherency is gaining traction across a wide spectrum of applications as systems vendors begin leveraging heterogeneous computing to improve performance, minimize power, and simplify software development. Coherency is not a new concept, but making it easier to apply has always been a challenge. This is why it has largely been relegated to CPUs with identical processor cores. But the approach ... » read more

To Bus Or Not To Bus, That Is The Question

By Ann Steffora Mutschler When you hear the words, “block interface,” your ears may not perk up, but as system architects well understand, making the right choice between a bus or non-bus interface on an SoC is absolutely critical to design’s success in terms of power efficiency, reusability and performance. How many of the problems in new chip designs have to do with the interconne... » read more
