RISC-V Verification Challenges Spread
By Ann Mutschler - 22 Dec, 2020 - Comments: 0

The RISC-V ecosystem is struggling to keep pace with rapid innovation and customization, which is increasing the amount of verification work required for each design and spreading that work out across more engineers at more companies. The historical assumption is that verification represents 60% to 80% or more of SoC project effort in terms of cost and time for a mature, mainstream processor... » read more

Simplifying And Speeding Up Verification

The Increasingly Ordinary Task Of Verifying RISC-V
By Ann Mutschler - 03 Jun, 2020 - Comments: 0

As RISC-V processor development matures and its usage in SoCs and microcontrollers grows, engineering teams are starting to look beyond the challenges of the processor core itself. So far, the majority of industry verification efforts have focused on ISA compliance to standardize the RISC-V core. Now the focus is shifting to be how to handle verification as the system grows, especially as this... » read more

AI’s Impact On Power And Performance
By Ed Sperling - 14 Nov, 2019 - Comments: 0

AI/ML is creeping into everything these days. There are AI chips, and there are chips that include elements of AI, particularly for inferencing. The big question is how well they will affect performance and power, and the answer isn't obvious. There are two main phases of AI, the training and the inferencing. Almost all training is done in the cloud using extremely large data sets. In fact, ... » read more

Revving Up For Edge Computing
By Ed Sperling - 07 Nov, 2019 - Comments: 1

The edge is beginning to take shape as a way of limiting the amount of data that needs to be pushed up to the cloud for processing, setting the stage for a massive shift in compute architectures and a race among chipmakers for a stake in a new and highly lucrative market. So far, it's not clear which architectures will win, or how and where data will be partitioned between what needs to be p... » read more

Week in Review – IoT, Security, Autos

Superconductivity seen in trilayer graphene Stanford University and University of California at Berkeley researchers discovered signs of superconductivity in stacking three-layer sheets of graphene, they report. “It’s definitely an exciting development,” says Cory Dean, a physicist at Columbia University. Dean notes that bilayer graphene superconducts only when the atomic lattices of ... » read more

Transparent film is stronger than aluminum Professor Ton Peijs of WMG at the University of Warwick and Professor Cees Bastiaansen at Queen Mary University of London came up with a new processing technique that produces a transparent polythene film said to be stronger than aluminum. The film could be used in displays, glazing, visors, and windshields, without adding significant weight. The d... » read more

In-Memory Computing Challenges Come Into Focus
By Katherine Derbyshire - 06 Feb, 2019 - Comments: 6

For the last several decades, gains in computing performance have come by processing larger volumes of data more quickly and with superior precision. Memory and storage space are measured in gigabytes and terabytes now, not kilobytes and megabytes. Processors operate on 64-bit rather than 8-bit chunks of data. And yet the semiconductor industry’s ability to create and collect high quality ... » read more
