Week In Review: Manufacturing, Test


Chipmakers The chip industry is buzzing over a Wall Street Journal report that Intel is in talks to buy GlobalFoundries (GF) for $30 billion. In March, Intel re-entered the foundry business, positioning itself against Samsung and TSMC at the leading edge, and against a multitude of foundries working at older nodes. Intel planned to jumpstart its foundry business within its own fabs. But it... » read more

Week In Review: Manufacturing, Test


Market research For some time, China has faced an enormous trade gap in semiconductors. In response, China has been developing its semiconductor industry with plans to make more of its chips. But China is expected to fall far short of its “Made in China 2025” goals for IC production, according to IC Insights. “IC Insights forecasts China-produced ICs will represent only 19.4% of its I... » read more

Mixing Interface Protocols


Continuous and pervasive connectivity requires devices to support multiple interface protocols, but that is creating problems at multiple levels because each protocol is based on a different set of assumptions. This is becoming significantly harder as systems become more heterogeneous and as more functions are crammed into those devices. There are more protocols that need to be supported to ... » read more

eFPGA Acceleration in SoCs


The Speedcore design and integration methodology has been defined with intimate awareness of the difficulties ASIC engineering teams must contend with. All the necessary files and flows for capturing the functional, timing and power characteristics of a user-defined and programmed Speedcore instance, along with support for successfully reconfiguring an already field-deployed Speedcore IP embedd... » read more

How Cache Coherency Impacts Power, Performance


As discussed in part one, one of the reasons cache coherency is becoming more important is the shared common memory resource in designs today. Various agents in the design want to access the data the fastest they can, putting pressure on the CPU complex to manage all of the requests. Until a generation ago, it was okay for the CPU to control that memory and have access to it, as well as be t... » read more

Executive Insight: K. Charles Janac


K. Charles Janac, chairman and CEO of Arteris, sat down with Semiconductor Engineering to talk about what's changing in the automotive market, the impact of big data, and heterogeneous cache coherency. What follows are excerpts of that discussion. SE: What are the big changes you're seeing in semiconductor design? Janac: There are a lot of changes right now. Mobility is slowing down and b... » read more

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

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

Blog Review: Dec. 31


Mentor's J. VanDomelen zeroes in on the two most interesting discoveries from the Philae comet landing. So what was that "eerie cyclical clicking" sound? Synopsys' Ray Varghese digs into basic coherent transaction testing for AXI/ACE compliant interconnects. You might want to put on another pot of coffee. Cadence's Brian Fuller offers some deep insights into synthesis, verification and te... » read more

Executive Insight: Simon Segars


SE: What concerns you most? Segars: In the context of design and where chip design is going, ARM is a long-term business. We’re doing stuff now that is going to ship in five years’ time. Obviously, for everyone in this space, Moore’s Law has been a fantastic thing. It’s enabled us to achieve really fantastic scaling of transistors, and everyone knows that is getting harder and harder... » read more
