Will Wide I/O Reduce Cache?


By Ann Steffora Mutschler In an ideal world, all new SoC technologies would make the lives of design engineers easier. While this may be true of some techniques, it is not the case with one advanced memory interface technology on the horizon, Wide I/O. There are claims that Wide I/O could reduce cache, but so far this is not widely understood. In fact, exactly how Wide I/O will be used, wha... » read more

Wide I/O’s Impact On Memory


By Ann Steffora Mutschler Driven by the need to reduce power but increase bandwidth in smart phones and other mobile devices, system architects are grappling with new technologies to take system performance to the next level. Wide I/O, as well as some DDR technologies, are vying for center stage in tomorrow’s leading-edge mobile designs. “The big technological advancement that allows a ... » read more

Customer Perspective: STMicroelectronics


By Ed Sperling Philippe Magarshack, group vice president for technology R&D at STMicroelectronics, sat down with Low-Power Engineering to talk about some of the fundamental changes ahead in how SoCs are designed, built, how they perform and what steps can be taken to speed time to market. LPE: What do you see as the biggest changes ahead? Magarshack: One is the sheer size of the ecosy... » read more

Memory, Bandwidth And SoC Performance


By Ann Steffora Mutschler High-end SoC architectures today can contain dozens of processing engines—multiple cores from MIPS and ARM, DSPs from Tensilica and CEVA, and even graphics processors. But with so many cores there also is a need for enormous amounts of memory, and that has been creating some unexpected design problems, In many cases so much memory is required for an SoC that some... » read more
