Week In Review: Design, Low Power


VESA published the DisplayPort 2.0 standard, which allows for a max payload of 77.37 Gbps, a 3X increase in data bandwidth performance compared to DisplayPort 1.4a. The latest release also includes capabilities to address beyond 8K resolutions, higher refresh rates and HDR support at higher resolutions, multiple display configurations, and support for 4K-and-beyond VR resolutions. It is backwar... » read more

Taking Steps Toward Hybrid Memory


What is the memory subsystem of the future, and how do we get there? Since our Hybrid Memory research program began, Rambus Labs and its industry partners and collaborators have made significant progress under the banner of OpenPOWER and OpenCAPI Foundations, an open development community based on the POWER microprocessor (mP) architecture. Rambus Labs is using the Wistron POWER9 systems’ Ope... » read more

Pushing DRAM’s Limits


If humans ever do create a genuinely self-aware artificial intelligence, it may well exhibit the frustration of waiting for data arrive. The access bandwidth of DRAM-based computer memory has improved by a factor of 20x over the past two decades. Capacity increased 128x during the same period. But latency improved only 1.3x, according to Kevin Chang, a researcher at Carnegie Mellon Universit... » read more

Targeting And Tailoring eFPGAs


Robert Blake, president and CEO of Achronix, sat down with Semiconductor Engineering to discuss what's changing in the embedded FPGA world, why new levels of customization are so important, and difficulty levels for implementing embedded programmability. What follows are excerpts of that discussion. SE: There are numerous ways you can go about creating a chip these days, but many of the prot... » read more

Architecture First, Node Second


What a difference a node makes. A couple of rather important changes have occurred in the move from 16/14 to 10/7nm (aside from more confusing naming conventions). First, companies that require more transistors—processor companies such as [getentity id="22846" e_name="Intel"], AMD, [getentity id="22306" comment="IBM"] and [getentity id="22676" e_name="Qualcomm"]—have come to grips with t... » read more
