Coherency: The New Normal In SoCs


We are not far from devices each handling 100 teraflops of compute, billions of pixels of display, hundreds of gigabits of connectivity, and terabytes of storage. Compared with current state-of-the-art mobile SoCs, these are increases of one or two orders of magnitude — at similar or preferably lower power consumption. SoC design is changing to meet this challenge. Multicore architecture i... » read more

Adapt Or Perish: A Unified Theory Of Coherency


Evolution is a natural process and more importantly a relatively slow process that has eventually got us here, capable of perceiving, analyzing, and handling complex tasks. As our environment, society, and surroundings became more complex we learned how to adapt at a brisk and instantaneous manner, in this melting pot of a heterogeneous world. The evidence can be seen in all ages, from the poli... » read more

The Mightier Microcontroller


Microcontrollers are becoming more complex, more powerful, and significantly more useful, but those improvements come with strings attached. While it's relatively straightforward to develop multi-core microcontroller (MCU) hardware with advanced power management features, it's much more difficult to write software for these chips because memory is limited. CPUs can use on-chip memory such as... » read more

What Is Coherency?


Coherency is about ensuring all processors, or bus masters in the system see the same view of memory. Cache coherency means that all components have the same view of shared data. Just as you need both of your eyes to have the same view in order to see properly, it’s critical for every IP block that has access to a shared data source to view consistent data. For example, if I have a process... » read more

Experts At The Table: Coherency


System-Level Design sat down to discuss coherency with Mirit Fromovich, principal solutions engineer at Cadence; Drew Wingard, CTO of Sonics; Mike Gianfagna, vice president of marketing at Atrenta, and Marcello Coppola, technical director at STMicroelectronics. What follow are excerpts of that conversation. SLD: We’ve been hearing a lot about Wide I/O. Why is it so important and what effec... » read more
