Week In Review: Design, Low Power


Rambus finalized its acquisition of the silicon IP, secure protocols and provisioning business from Verimatrix, formerly Inside Secure, for $45 million at closing, and up to an additional $20 million, subject to certain revenue targets in 2020. RISC-V SiFive unveiled two new product families. The SiFive Apex processor cores target mission-critical processors with Size, Weight, and Power (SW... » read more

Week in Review: IoT, Security and Automotive


Internet of Things Western Digital Corp. and Codasip are working together on Western Digital’s SweRV Core EH1, which is a RISC-V core with a 32-bit, dual superscalar, 9-stage pipeline architecture. The core, launched earlier this is aimed at embedded devices supporting data-intensive edge applications, such as storage controllers, industrial IoT, real-time analytics in surveillance systems, ... » read more

System-in-Package For Heterogeneous Designs


System integration is increasingly being done using 3D packaging technologies rather than integrating everything onto a huge SoC. One motivation is the ability to not just to split up a design in a single process, but to package die from different processes. Sometimes there are economic reasons. Several presentations at HOT CHIPS had a partition of the design into the processor itself, and a... » read more

Interdependencies Complicate IC Power Grid Design


Creating the right power grid is a growing problem in leading-edge chips. IP and SoC providers are spending a considerable amount of time defining the architecture of logic libraries in order to enable different power grids to satisfy the needs of different market segments. The end of Dennard scaling is one of the reasons for the increased focus. With the move to smaller nodes, the amount of... » read more

A New Dawn For IP


The IP industry is changing again. The concept started as build once, use everywhere, but today it is more like architect once, customize everywhere. Few designs can afford sub-optimal IP for their application. The need for customized IP is driven by both leading-edge designs and the trailing markets, although for different reasons. While this customization is causing IP companies to transfo... » read more

Defining And Improving AI Performance


Many companies are developing AI chips, both for training and for inference. Although getting the required functionality is important, many solutions will be judged by their performance characteristics. Performance can be measured in different ways, such as number of inferences per second or per watt. These figures are dependent on a lot of factors, not just the hardware architecture. The optim... » read more

System Electrothermal Transient Analysis of A High Current (40A) Synchronous Step Down Converter


Authors: Rajen Murugan, Jie Chen, and Todd Harrison of Texas Instruments, Inc. and C.T. Kao and Nathan Ai of Cadence Design Systems; from Proceedings of the ASME 2019 International Technical Conference and Exhibition on Packaging and Integration of Electronic and Photonic Microsystems, IPACK2019, October 7-9, 2019, Anaheim, CA, USA In this paper, we detailed the system electrothermal transi... » read more

Blog Review: Dec. 11


Arm's Urmish Thakker investigates ways to make recurrent neural networks run on resource constrained devices with limited cache and compute resources by reducing the number of RNN computations, without the need to retrain the original RNN model. Mentor's Brent Klingforth digs into the challenges of designing rigid-flex PCBs and how advanced capabilities in modern tools, like awareness of sta... » read more

5 Major Shifts In Automotive


Much of the automotive industry has begun repositioning and retrenching over the past few months, pushing back the projected rollout for fully autonomous vehicles and changing direction on power sources and technology used in the next-generation of electric vehicles. Taken together, these shifts mark a significant departure for traditional automakers, which find themselves playing catch-up t... » read more

Week In Review: Manufacturing, Test


Chipmakers United Microelectronics Corp. (UMC) has announced the readiness of its new 22nm process. The process enables new 22nm designs or allows customers to migrate from 28nm to 22nm. UMC’s 22nm maintains its existing 28nm design architectures. UMC's 22nm process features a 10% area reduction, better power-to-performance ratio and enhanced RF capabilities, compared to the company’s 2... » read more
