The Rise Of Complex Debug On Heterogeneous Multicore SoCs

When projects move away from discrete development of loosely coupled systems to an integrated heterogeneous environment, elephantine debugging challenges are created. These challenges do not exist during discrete development because developers are able to design, develop, test, and optimize within the confines of their own device. But when consolidating heterogeneous systems, developers and ... » read more

Not All Workloads Are Equal

ARM's Ben and Otilia put a human face big on processing — who sleeps, who works, when they do each, and and what's behind their decision. Check out the video: [youtube vid=J2z7P9JKukc] big.LITTLE uses a heterogeneous multi-core approach to power optimization, where high-performance CPU cores are combined with the most efficient CPU cores to deliver peak-performance capacity, higher s... » read more

The Interconnect Bottleneck

With communications playing a crucial role in the design and performance of multi-core SoCs, various interconnect structures have been proposed as promising solutions to simplify and optimize SoC design. However, sometimes things don’t go as planned and the interconnect becomes the bottleneck. “Under high utilization cases the DRAM will be over-constrained with requests from all the a... » read more

Addressing Design Challenges In Heterogeneous Multicore Embedded Systems

Single-core processor designs for purpose-built devices used to rule the day. Now, heterogeneous multicore systems are quickly becoming the de facto architecture as devices are tasked to do more complex functions faster and more efficiently. In this paper, we’ll explore why hetero/multicore systems have become so popular and why many of our current procedures and practices must change if we a... » read more

The Week In Review: Design

Tools Cadence unveiled two new tools. The first is a rapid prototyping platform that the company claims will shorten bring-up time by 70%, with 4X improvements in capacity, with IEEE 1801 support for low-power verification through its emulation platform. The second is a single and multi-corner custom/analog extraction tool, which it claims will improve performance by 5X. The tool has been cert... » read more
