Side-Channel Attack “Binoculars” Exploits Interactions Between HW Page Walk Operations & Other Memory Operations


New technical paper titled "Binoculars: Contention-Based Side-Channel Attacks Exploiting the Page Walker" was presented by researchers at University of Illinois Urbana-Champaign and Tel Aviv University at the USENIX Security Symposium in Boston in August 2022. Abstract: "Microarchitectural side channels are a pressing security threat. These channels are created when programs modulate hardw... » read more

Technical Paper Round-Up: July 5


New technical papers added to Semiconductor Engineering’s library this week. [table id=36 /] Semiconductor Engineering is in the process of building this library of research papers. Please send suggestions (via comments section below) for what else you’d like us to incorporate.

Flexible Microprocessors (FlexiCores)- Natively flexible 4-bit and 8-bit microprocessors optimized for low footprint and yield


New research paper titled "FlexiCores: low footprint, high yield, field reprogrammable flexible microprocessors" from researchers at University of Illinois and PragmatIC Semiconductor. Abstract "Flexible electronics is a promising approach to target applications whose computational needs are not met by traditional silicon-based electronics due to their conformality, thinness, or cost requir... » read more

Power/Performance Bits: Feb. 7


Stopping interference in integrated photonics Researchers at EPFL and Purdue University combined integrated photonics and MEMS to develop an electrically driven optical isolator-on-a-chip that transmits light in only one direction. Optical isolators are useful to prevent reflected light from other components compromising or interfering with an on-chip laser’s performance. They are often c... » read more

Execution Dependence Extension (EDE): ISA Support For Eliminating Fences


Fence instructions are a coarse-grained mechanism to enforce the order of instruction execution in an out-of-order pipeline. They are an overkill for cases when only one instruction must wait for the completion of one other instruction. For example, this is the case when performing undo logging in Non-Volatile Memory (NVM) systems: while the update of a variable needs to wait until the correspo... » read more

Manufacturing Bits: Sept. 28


Self-healing ceramics Texas A&M University has discovered a new self-healing mechanism for ceramics, a technology that could one day be used for jet engines, hypersonic aircraft and nuclear reactors. Ceramics involve various materials that are neither metallic nor organic, but rather they are crystalline and/or glassy, according to the University of Maryland. One common example is clay,... » read more

Week In Review: Manufacturing, Test


Government policy The U.S. government hopes to build more fabs and expand its R&D efforts in the United States. To help enable those efforts, U.S. Senate Majority Leader Charles Schumer has introduced the new bipartisan U.S. Innovation and Competition Act. This combines Schumer’s Endless Frontier Act and other bipartisan competitiveness bills. It includes $52 billion in emergency supplem... » read more

Week In Review: Design, Low Power


Valens Semiconductor will become a publicly traded company on NYSE as VLN after a merger with PTK Acquisition Corp. Valens provides long-reach, high-speed video and data transmission for the audio-video and automotive industries. The transaction is expected to provide proceeds of approximately $240 million, including up to $115 million in trust from PTK Acquisition Corp. (assuming no redemption... » read more

Power/Performance Bits: April 20


Multiplexing twisted light Researchers from University of California San Diego and University of California Berkeley found a way to multiplex light by using discrete twisting laser beams from antennas made up of concentric rings. "It's the first time that lasers producing twisted light have been directly multiplexed," said Boubacar Kanté, an Associate Professor at UC Berkeley's Department ... » read more
