Rethinking Architectures Based On Power


The newest chips being developed for everything from the cloud to the edge of the network look nothing like designs of even a year or two ago. They are architected for speed, from the throughput of high-speed buses and external interconnects to the customized accelerators and arrays of redundant MACs. But many of these designs have barely scratched the surface for saving power, which will becom... » read more

Power Impact At The Physical Layer Causes Downstream Effects


Data movement is rapidly emerging as one of the top design challenges, and it is being complicated by new chip architectures and physical effects caused by increasing density at advanced nodes and in multi-chip systems. Until the introduction of the latest revs of high-bandwidth memory, as well as GDDR6, memory was considered the next big bottleneck. But other compute bottlenecks have been e... » read more

Challenges For Compute-In-Memory Accelerators


A compute-in-memory (CIM) accelerator does not simply replace conventional logic. It's a lot more complicated than that. Regardless of the memory technology, the accelerator redefines the latency and energy consumption characteristics of the system as a whole. When the accelerator is built from noisy, low-precision computational elements, the situation becomes even more complex. Tzu-Hsian... » read more

3 Challenges In Edge Designs


As companies begin exploring what will be necessary to win at the edge, they are coming up with some daunting challenges. Designing chips for the edge is far different than for the IoT/IIoT. The idea with the IoT was that simple sensors would relay data through a gateway to the cloud, where it would be processed and data could be sent back to the device as needed. That works if it's a small ... » read more

Conflicting Demands At The Edge


Semiconductor Engineering sat down to define what the edge will look like with Jeff DeAngelis, managing director of the Industrial and Healthcare Business Unit at Maxim Integrated; Norman Chang, chief technologist at Ansys; Andrew Grant, senior director of artificial intelligence at Imagination Technologies; Thomas Ensergueix, senior director of the automotive and IoT line of business at Arm; V... » read more

Design For Narrowband IoT


Most low-power chips are designed with the assumption that batteries can be recharged or replaced, but there is a whole set of IoT devices under development that are expected to be always-on, communicate over a cellular infrastructure, and remain functional on a coin-sized lithium-ion battery for a decade or more. Welcome to the world of Narrowband IoT (NB-IoT), a 3GPP standard (also known a... » read more

Who Owns A Car’s Chip Architecture


Kurt Shuler, vice president of marketing at Arteris IP, examines the competitive battle brewing between OEMs and Tier 1s over who owns the architecture of the electronic systems and the underlying chip hardware. This has become a growing point of contention as both struggle for differentiation in a market where increasingly autonomous vehicles will all behave the same way. That, in turn, has si... » read more

Power Becomes Bigger Concern For Embedded Processors


Power is emerging as the dominant concern for embedded processors even in applications where performance is billed as the top design criteria. This is happening regardless of the end application or the process node. In some high-performance applications, power density and thermal dissipation can limit how fast a processor can run. This is compounded by concerns about cyber and physical secur... » read more

Power-Hungry Safety And Security


There is a price to pay for everything. When it comes to adding safety and security into a device, the costs in terms of power and area can be significant, but if the task is taken seriously, those costs can be managed and minimized. New analysis and implementation tools are coming to market that can also help to keep the costs contained. But it also requires the right mindset. As more indus... » read more

Last-Level Cache


Kurt Shuler, vice president of marketing at Arteris IP, explains how to reduce latency and improve performance with last-level cache in order to avoid sending large amounts of data to external memory, and how to ensure quality of service on a chip by taking into account contention for resources. » read more
