DSP Techniques For High-Speed SerDes


Sensors everywhere, more connected devices, and the rollout of smart everything has created a flood of data. The question now is how to best handle all of that data, where to process it, and how to move it locally and to the outside network. Madhumita Sanyal, technical product manager at Synopsys, talks about the need for continuous performance improvements in SerDes, PCIe, NRZ, and PAM4, and w... » read more

How Sub-THz Will Impact the Future Of 6G


By Alejandro Escobar Calderon and Gerardo Orozco The world is more connected than ever before and, while this notion isn’t new, many of us fail to fully grasp at times the magnitude of connection growth speed. As of 2022, the world had around 13.2B IoT connections (Ericsson Mobile) with a YoY growth of 13%. Additionally, mobile network data traffic has doubled every two years since 2019. T... » read more

CXL Memory: Detailed Characterization Analysis Using Micro-Benchmarks And Real Applications (UIUC, Intel Labs)


A new technical paper titled "Demystifying CXL Memory with Genuine CXL-Ready Systems and Devices" was published by researchers at University of Illinois Urbana-Champaign (UIUC) and Intel Labs. Abstract: "The high demand for memory capacity in modern datacenters has led to multiple lines of innovation in memory expansion and disaggregation. One such effort is Compute eXpress Link (CXL)-based... » read more

Dealing With Performance Bottlenecks In SoCs


A surge in the amount of data that SoCs need to process is bogging down performance, and while the processors themselves can handle that influx, memory and communication bandwidth are straining. The question now is what can be done about it. The gap between memory and CPU bandwidth — the so-called memory wall — is well documented and definitely not a new problem. But it has not gone away... » read more

Boosting Data Center Memory Performance In The Zettabyte Era With HBM3


We are living in the Zettabyte era, a term first coined by Cisco. Most of the world’s data has been created over the past few years and it is not set to slow down any time soon. Data has become not just big, but enormous! In fact, according to the IDC Global Datasphere 2022-2026 Forecast, the amount of data generated over the next 5 years will be at least 2x the amount of data generated over ... » read more

HBM3 In The Data Center


Frank Ferro, senior director of product management at Rambus, talks about the forthcoming HBM3 standard, why this is so essential for AI chips and where the bottlenecks are today, what kinds of challenges are involved in working with this memory, and what impact chiplets and near-memory compute will have on HBM and bandwidth.     » read more

Novel In-Pixel-in-Memory (P2M) Paradigm for Edge Intelligence (USC)


A new technical paper titled "A processing-in-pixel-in-memory paradigm for resource-constrained TinyML applications" was published by researchers at University of Southern California (USC). According to the paper, "we propose a novel Processing-in-Pixel-in-memory (P2M) paradigm, that customizes the pixel array by adding support for analog multi-channel, multi-bit convolution, batch normaliza... » read more

Review of Bumpless Build Cube Using Wafer-on-Wafer & Chip-on-Wafer for Tera-Scale 3D Integration


New research paper titled "Review of Bumpless Build Cube (BBCube) Using Wafer-on-Wafer (WOW) and Chip-on-Wafer (COW) for Tera-Scale Three-Dimensional Integration (3DI)" from researchers at Tokyo Institute of Technology and others. Abstract "Bumpless Build Cube (BBCube) using Wafer-on-Wafer (WOW) and Chip-on-Wafer (COW) for Tera-Scale Three-Dimensional Integration (3DI) is discussed. Bum... » read more

Automotive Bandwidth Issues Grow As Data Skyrockets


Bandwidth requirements for future vehicles are set to explode as the amount of data moving within vehicles, between vehicles, and between vehicles and infrastructure, continues to grow rapidly. That data will be necessary for a variety of functions, some of which are here today and many of which are still in development. On the safety side, that includes everything from early warning systems... » read more

Measuring Frequency Dependence Across 5G mmWave Bands (NIST)


New research paper from NIST, "Methodology for Measuring the Frequency Dependence of Multipath Channels Across the Millimeter-Wave Spectrum." Abstract "Millimeter-wave (mmWave) communications promise Gigabit/s data rates thanks to the availability of large swaths of bandwidth between 10–100 GHz. Although cellular operators prefer the lower portions of the spectrum due to popular belief ... » read more
