Where Power Is Spent In HBM

HBM is gaining ground because of a spike in the amount of data that needs to be processed quickly, but big reductions in power are possible if that processing can be moved closer to the HBM modules, and if more can be done in each compute cycle without sending data back and forth to memory as frequently. Steven Woo, fellow and distinguished engineer at Rambus, talks about what can be done to bo... » read more

Choosing The Right Memory At The Edge

As the amount of data produced by sensors in cars and phones continues to grow, more of that data needs to be processed locally. It takes too much time and power to send it all to the cloud. But choosing the right memory for a particular application requires a series of tradeoffs involving cost, bandwidth, power, which can vary greatly by device, application, and even the data itself.

Managing IP In Heterogeneous Designs

Increasing complexity and heterogeneity is creating huge challenges for tracking different versions of IP over the lifetime of chips. Pedro Pires, applications engineer at ClioSoft, talks about the implications of IP reuse in a complex, multi-IP context, including how different standards and database formats can affect IP tracking and why an interoperability layer is essential to tracking IP an... » 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

Quantum Computing

Sebastian Luber, senior director of technology and innovation at Infineon Technologies, talks about the growing interest in quantum computers, what’s still missing to make this technology more relevant, and how to improve the lifespan and accuracy of qubits. » read more

Boosting Data Management System Performance

Marios Karatzias, application engineer at ClioSoft, talks with Semiconductor Engineering about the increasing use and re-use of IP in designs, how to best keep track of that IP, and how to optimize the performance of the data management system to deal with IP in heterogeneous chips. This is particularly important in automotive and industrial applications, where a specific version of IP may have... » read more

Co-Packaged Optics In The Data Center

Just because faster Ethernet is added to the data center doesn’t mean existing hardware can utilize it efficiently. Scott Durrant, strategic marketing manager at Synopsys, talks with Semiconductor Engineering about the rapid rollout of faster Ethernet rates, problems in moving data to the front module of the switch and how much energy is required, and what optical technology can bring to the ... » read more

The Ethernet Evolution

Ethernet was expected to be long gone by now, but predictions of its demise were decades premature. John Swanson, senior product marketing manager for high-performance computing digital IP at Synopsys, talks about how Ethernet has evolved over the past 45 or so years from a somewhat “boring” technology to one that is at the forefront of data center performance improvements, with more update... » read more

Always-On DSPs

There are tradeoffs between powering circuits down to save power and waking them up to respond to voice and visual commands. Prakash Madhvapathy, director of product marketing and product management at Cadence, talks about the best ways to deploy digital signal processors, why multiple DSPs are often better than just one, and what penalties there are for various approaches. » read more

Low-Power Always-On Circuits

Some circuits are always on. A smart phone wakes up when it senses a user, and a smart speaker responds to keywords. The challenge is to make sure these devices don’t consume a lot of power while the rest of a device is powered down, that it remains secure, and that it can quickly wake up whatever other functions are needed. All of this requires a significant amount of engineering work. Amol ... » read more
