Week In Review: Design, Low Power
By Jesse Allen - 10 Dec, 2021 - Comments: 0

Intel intends to take Mobileye public in mid-2022 on a US market through an IPO of newly issued stock. The subsidiary, which Intel acquired in 2017, develops SoCs for ADAS and autonomous driving solutions. Mobileye has achieved record revenue year-over-year with 2021 gains expected to be more than 40 percent higher than 2020, highlighting the powerful benefits to both companies of our ongoing p... » read more

Week In Review: Auto, Security, Pervasive Computing
By SE Staff - 10 Dec, 2021 - Comments: 0

Pervasive computing An outage in network equipment at the US-EAST-1 Region of Amazon Web Services this week reminded customers of the downside to having every appliance run via a data center. Users accessing apps tied to AWS on the East coast found services did not work, including Alexa, Ring, smart appliances, some Amazon warehouses and packaging delivery, web APIs such as Slack, and some str... » read more

Scaling DDR5 RDIMMs To 5600 MT/s
By John Eble - 09 Dec, 2021 - Comments: 0

Looking forward to 2022, the first of the DDR5-based servers will hit the market with RDIMMs running at 4800 megatransfers per second (MT/s). This is a 50% increase in data rate over top-end 3200 MT/s DDR4 RDIMMs in current high-performance servers. DDR5 memory incorporates a number of innovations, such as Decision Feedback Equalization (DFE), and a new DIMM architecture which enable that speed... » read more

Innovations In Sensor Technology
By John Koon - 09 Dec, 2021 - Comments: 0

Sensors are the “eyes” and “ears” of processors, co-processors, and computing modules. They come in all shapes, forms, and functions, and they are being deployed in a rapidly growing number of applications — from edge computing and IoT, to smart cities, smart manufacturing, hospitals, industrial, machine learning, and automotive. Each of these use cases relies on chips to capture d... » read more

Improving Energy And Power Efficiency In The Data Center
By Ann Mutschler - 06 Dec, 2021 - Comments: 0

Energy costs in data centers are soaring as the amount of data being generated explodes, and it's being made worse by an imbalance between increasingly dense processing elements that are producing more heat and uneven server utilization, which requires more machines to be powered up and cooled. The challenge is to maximize utilization without sacrificing performance, and in the past that has... » read more

Architecting Hardware Protection For Data At Rest And In Motion
By Bart Stevens - 02 Dec, 2021 - Comments: 0

Planning the security architecture for any device begins with the threat model. The threat model describes the types of attacks that the device or application may face and needs to be protected against. It is based on what attackers can do, what level of control they have over the product (i.e., remote or direct access), and how much effort and money they are willing and able to spend on an att... » read more

Why It’s So Difficult — And Costly — To Secure Chips
By Ed Sperling - 02 Dec, 2021 - Comments: 0

Rising concerns about the security of chips used in everything from cars to data centers are driving up the cost and complexity of electronic systems in a variety of ways, some obvious and others less so. Until very recently, semiconductor security was viewed more as a theoretical threat than a real one. Governments certainly worried about adversaries taking control of secure systems through... » read more

Anti-Tamper Benefits Of Encrypted Helper-Data Images For PUFs
By Rambus - 01 Dec, 2021 - Comments: 0

PUFs are mixed-signal circuits which rely on variations unique to a specific chip to self-generate a digital “fingerprint.” Most PUFs require a “helper-data” image that is generated during the initial digitization process, also known as Enrollment. Leveraging the chip-unique transformation function of PUFs and encrypted helper data, an unclonable challenge-response mechanism can be impl... » read more

Week In Review: Design, Low Power
By Jesse Allen - 19 Nov, 2021 - Comments: 0

Tools Imperas Software released updated simulator and reference models that support the latest RISC-V extensions for Bit Manipulation 1.0.0, Cryptographic (Scalar) 1.0.0, and Vector 1.0, plus Privilege Specification 1.12. They are offered both as freely available, open-source reference models for the RISC-V community as well as commercial products. Ansys' multiphysics signoff solutions were... » read more

Blog Review: Nov. 17
By Jesse Allen - 17 Nov, 2021 - Comments: 0

In a podcast, Arm's Geof Wheelwright and Hilary Tam chat about the importance of efforts to decarbonize compute and how low-power compute can help ensure that the benefits of technology outweigh the environmental cost. Synopsys' Graham Allan and Vikas Gautam consider what's driving demand for HBM3, what's different from the previous HBM2E specification, unique design considerations, and how ... » read more
