IP and SDK accelerate on-device and edge AI design, says Cadence

AI IP and software tools to address the escalating demand for on-device and edge AI processing have been unveiled by Cadence. The scalable Cadence Neo neural processing units (NPUs) deliver a range of AI performance in a low-energy footprint, said the company and this is claimed to bring new levels of performance and efficiency to AI SoCs.
The Neo NPUs deliver up to 80TOPS performance in a single core, in order to support both classic and new generative AI models. They can also offload AI/ML execution from any host processor, including application processors, general-purpose microcontrollers and DSPs. This is achieved with a simple and scalable AMBA AXI interconnect.
Cadence has also introduced the NeuroWeave software development kit (SDK) which it said provides developers with a “one-tool” AI software solution across Cadence AI and Tensilica IP products for no-code AI development.
“While most of the recent attention on AI has been cloud-focused, there are an incredible range of new possibilities that both classic and generative AI can enable on the edge and within devices,” pointed out Bob O’Donnell, president and chief analyst at TECHnalysis Research. For these intuitive, intelligent devices to be realised will need a flexible, scalable combination of hardware and software solutions with a range of power requirements and compute performance, “all while leveraging familiar tools” he believed. “New chip architectures that are optimised to accelerate ML models and software tools with seamless links to popular AI development frameworks are going to be incredibly important parts of this process,” he added.
The Neo NPUs are suitable for power-sensitive devices as well as high-performance systems with a configurable architecture. SoC architects will be able to integrate an optimal AI inferencing solution in a range of products, including intelligent sensors, IoT and mobile devices, cameras, hearables/wearables, PCs, AR/VR headsets and advanced driver-assistance systems (ADAS). New hardware and performance enhancements and key features/capabilities include:
The single core NPUs are scalable from 8GOPS to 80TOPS, with further extension to hundreds of TOPS with multi-core devices, said Cadence. They support 256 to 32K MACs per cycle, allowing SoC architects to optimise embedded AI to meet power, performance and area (PPA) tradeoffs.
Offloading of inferencing tasks from any host processor (e.g., DSPs, general-purpose microcontrollers or application processors) significantly improves system performance and power, said Cadence.
Support for Int4, Int8, Int16 and FP16 data types across a wide set of operations that form the basis of CNN, RNN and transformer-based networks allows flexibility in neural network performance and accuracy tradeoffs while the NPUs offer up to 20 times higher performance than the first-generation Cadence AI IP, with two to five time the inferences per second per area (IPS/mm2) and five to 10 times the inferences per second per Watt (IPS/W)

PowerHap development starter kit provides design feedback

A development starter kit for fast haptics prototyping gives mechanical designers and engineers a first impression of haptic feedback with PowerHap piezo actuators. The kit by TDK shows how the mechanical integration works, and provides a reference design, which can be adapted to various applications.
TDK’s PowerHap piezo actuators offer haptic feedback based on acceleration, force, and response time. They can be used in automotive designs (e.g., steering wheels, displays, dashboards, buttons), smartphones, displays and tablets, household appliances, ATMs and vending machines, game controllers, VR gloves, industrial equipment and medical devices.
The PowerHap Starter Kit (ordering code: Z63000Z2910Z01Z73) consists of a seamless button assembly (including PowerHap 1204H018V060 and PowerHap 1313H018V120), a round button assembly (incling PowerHap 1204H018V060), the BOS1901-Kit driver board from Boréas Technologies, additional PowerHap devices (including an FPC connection cable), USB cable, and a quick start user guide.
The BOS1901-Kit platform in the starter kit is pre-programmed for the seamless button and the round button for an immediate experience of sensing and haptics with the PowerHap actuators. The features of the Boréas platform make it easy to customise and tailor the haptic experience by adjusting the sensing detection parameters and the haptic feedback waveform.
TDK is based in Tokyo, Japan. It was established in 1935 to commercialise ferrite, a key material in electronic and magnetic products. Today, TDK‘s portfolio features passive components such as ceramic, aluminium electrolytic and film capacitors, as well as magnetics, high-frequency, and piezo and protection devices. The product spectrum also includes sensors and sensor systems such as temperature and pressure, magnetic, and MEMS sensors. In addition, TDK provides power supplies, energy devices and magnetic heads. Products are marketed under the product brands TDK, Epcos, InvenSense, Micronas, Tronics and TDK-Lambda.
TDK focuses on demanding markets in automotive, industrial and consumer electronics, and information and communication technology. The company has a network of design and manufacturing locations and sales offices in Asia, Europe, and in North and South America.
