Optimization Challenges For Safety And Security


Complexity challenges long-held assumptions. In the past, the semiconductor industry thought it understood performance/area tradeoffs, but over time it became clear this is not so simple. Measuring performance is no longer an absolute. Power has many dimensions including peak, average, total energy and heat, and power and function are tied together. Design teams are now dealing with the impl... » read more

New Approaches To Security


Different approaches are emerging to identify suspicious behavior and shut down potential breaches before they have a chance to do serious damage. This is becoming particularly important in markets where safety is an issue, and in AI and edge devices where the rapid movement of data is essential. These methods are a significant departure from the traditional way of securing devices through l... » read more

Heterogeneous Design Creating Havoc With Firmware Versions


Adding different kinds of processing elements into chips is creating system-level incompatibilities because of sometimes necessary, but usually uncoordinated, firmware updates from multiple vendors. In the past, firmware typically was synchronized with other firmware and the chip was verified and debugged. But this becomes much more difficult when multiple heterogeneous processing elements a... » read more

Week In Review: Design, Low Power


ON Semiconductor will acquire Quantenna Communications for $24.50 per share in an all cash transaction, representing an equity value of approximately $1.07 billion and enterprise value of approximately $936 million. Quantenna, a maker of Wi-Fi chipsets, was founded in 2006 and went public in late 2016. Tools & IP Achronix completed testing and is now demonstrating the 112 Gbps SerDes th... » read more

The Other Side Of Makimoto’s Wave


Custom hardware is undergoing a huge resurgence across a variety of new applications, pushing the semiconductor industry to the other side of Makimoto's Wave. Tsugio Makimoto, the technologist who identified the chip industry’s 10-year cyclical swings between standardization and customization, predicted there always will be room in ASICs for general-purpose processors. But it's becoming mo... » read more

The Challenge Of RISC-V Compliance


The open-source RISC-V instruction set architecture (ISA) continues to gain momentum, but the flexibility of RISC-V creates a problem—how do you know if a RISC-V implementation fits basic standards and can play well with other implementations so they all can run the same ecosystem? In addition, how do you ensure that ecosystem development works for all implementations and that all cores that ... » read more

Week In Review: Design, Low Power


RISC-V Western Digital announced big plans for RISC-V with a new open source RISC-V core, an open standard initiative for cache coherent memory over a network, and an open source RISC-V instruction set simulator. The SweRV Core features a 2-way superscalar design with a 32-bit, 9 stage pipeline core. It has clock speeds of up to 1.8Ghz on a 28mm CMOS process technology and will be used in vari... » read more

RISC-V: More Than a Core


The open-source RISC-V instruction set architecture (ISA) is attracting a lot of attention across the semiconductor industry, but its long-term success will depend on levels of cooperation never seen before in the semiconductor industry. The big question now is how committed the industry is to RISC-V's success. The real value that RISC-V brings is the promise of an ecosystem and the opportun... » read more
