Tachyum announces its Universal Processor Platform

Tachyum, a start-up based in San Jose, California with offices in Slovakia, unveiled its new processor family – codenamed “Prodigy” – that combines the advantages of CPUs with GP-GPUs, and specialized AI chips in a single universal processor platform. The company says its processor architecture attains ten times the processing power per watt compared to conventional designs.

A key innovation of the design is the ability to connect very fast transistor with very slow wires, but technical details on the device physics have not yet been disclosed.

The universal processor promises programming ease comparable to a CPU with performance and efficiency comparable to GP-GPU. It is designed to handle hyperscale workloads, AI, HPC, and other demanding applications

Tachyum claims its Prodigy universal processor will enable a super-computational system for real-time full capacity human brain neural network simulation by 2020. One target application would be the real-time Human Brain Project, where there’s a need for more than 1019 Flops (10,000,000,000,000,000,000 floating-point operations per second - 10 exaflop).

“Rather than build separate infrastructures for AI, HPC and conventional compute, the Prodigy chip will deliver all within one unified simplified environment, so for example AI or HPC algorithms can run while a machine is otherwise idle or underutilized,” said Tachyum CEO Dr. Radoslav ‘Rado’ Danilak. “Instead of supercomputers with a price tag in the hundreds of millions, Tachyum will make it possible to empower hyperscale datacenters to produce more work in a radically more efficient and powerful format, at a lower cost.”

“Despite efficiency gains from virtualization, cloud computing, and parallelism, there are still critical problems with datacenter resource utilization particularly at a size and scale of hundreds of thousands of servers,” said Christos Kozyrakis, professor of electrical engineering and computer science at Stanford, who leads the university’s Multiscale Architecture & Systems Team (MAST), a research group for cloud computing, energy-efficient hardware, and operating systems. “Tachyum’s breakthrough processor architecture will deliver unprecedented performance and productivity.” Kozyrakis is a corporate advisor to Tachyum.

MACOM and ST team to bring GaN on silicon to mainstream RF

MACOM and STMicroelectronics have agreed to develop GaN (Gallium Nitride) on Silicon wafers to be manufactured by ST for MACOM’s use across an array of RF applications.

MACOM said the deal provides it with increased Silicon wafer manufacturing capacity and improved cost structure. This could displace incumbent Silicon LDMOS and accelerate the adoption of GaN on Silicon in mainstream markets. ST and MACOM have been working together for several years to bring GaN on Silicon production up in ST’s CMOS wafer fab. As currently scheduled, sample production from ST is expected to begin in 2018.

“This agreement punctuates our long journey of leading the RF industry’s conversion to GaN on Silicon technology. To date, MACOM has refined and proven the merits of GaN on Silicon using rather modest compound semiconductor factories, replicating and even exceeding the RF performance and reliability of expensive GaN on SiC alternative technology,” said John Croteau, President and CEO, MACOM. “We expect this collaboration with ST to bring those GaN innovations to bear in a Silicon supply chain that can ultimately service the most demanding customers and applications.”

“ST’s scale and operational excellence in Silicon wafer manufacturing aims to unlock the potential to drive new RF power applications for MACOM and ST as it delivers the economic breakthroughs necessary to expand the market for GaN on Silicon,” said Marco Monti, President of the Automotive and Discrete Product Group, STMicroelectronics. “While expanding the opportunities for existing RF applications is appealing, we’re even more excited about using GaN on Silicon in new RF Energy applications, especially in automotive applications, such as plasma ignition for more efficient combustion in conventional engines, and in RF lighting applications, for more efficient and longer-lasting lighting systems."

Ampere emerges from stealth with 64-bit ARM server designs

Ampere, a start-up based in Santa Clara, California, emerged from stealth and revealed its plans for 64-bit ARM-based server processors aimed at hyperscale cloud applications and next-generation data centers.

Ampere Computing is headed by Renee James, the former president of Intel until 2016. Its team also includes three other Intel veterans: Atiq Bajwa, Chief Architect, and foremerly VP and GM of product architecture at Intel; Rohit Avinash Vidwans, Executive Vice President of Engineering, with 25 years experience at Intel including work on Xeon microprocessors for data center and enterprise servers; and Greg Favor, Senior Fellow, and 25 years experience at Intel including over 60 patents. Ampere is backed by The Carlyle Group.

Ampere said its processors will offer a high performance, custom core Armv8-A 64-bit server operating at up to 3.3 GHz, 1TB of memory at a power envelope of 125 watts. It will also offer mixed signal I/O features including PCIE Gen 3, SATA Gen 3, USB and workload accelerators, as well as the high-performance on-chip fabric. The processors are sampling now and will be in production in the second half of the year.

In October, The Carlyle Group acquired the compute business of AppliedMicro from MACOM, which earlier in 2017 acquired Applied Micro Circuits Corporation (AppliedMicro") in a deal was valued at approximately $770 million on the day it was announced.

In March 2017, AppliedMicro announced the sampling of its third generation 16-nanometer FinFET Server-on-a-Chip (SoC) solution, X-Gene 3.  The device is an ARMv8-A compatible processor that matches comparable x86 processors in CPU throughput, per-thread performance, and power efficiency while offering advantages in memory bandwidth and total cost of ownership. It features 32 ARMv8-A 64-bit cores operating at speeds up to 3.0 GHz, eight DDR4-2667 memory channels with ECC and RAS supporting up to 16 DIMMs and addressing up to 1TB of memory and 42 PCIe Gen 3 lanes with eight controllers.

“We have an opportunity with cloud computing to take a fresh approach with products that are built to address the new software ecosystem,” said James. “The workloads moving to the cloud require more memory, and at the same time, customers have stringent requirements for power, size and costs. The software that runs the cloud enables Ampere to design with a different point of view. The Ampere team’s approach and architecture meets the expectation on performance and power and gives customers the freedom to accelerate the delivery of the most memory-intensive applications and workloads such as AI, big data, storage and database in their next-generation data centers.”

Broadcom brings new Ethernet programmability with open source logical table software

Broadcom is introducing a new approach to Ethernet switch configuration that makes use of open source software to allow network hard vendors, OS vendors and even enterprise network managers to monitor, analyze, and provision switch resources through a standard software interface.

This capability is enabled by a new Software Development Kit Logical Table (SDKLT) for Broadcom switch ASICs that leverages table-based programming, where all the device physical resources such as MAC Address Tables, L3 route tables, TCAMs, etc. are exposed as logical tables. Device-specific information is stored in databases and not embedded in the APIs. Device-specific behavior is managed by logical tables through a small set of APIs. Broadcom said this approach introduces new ways to monitor, analyze and provision switch resources, all through industry standard automation tools. The company is making this logical table programmability available as an open source SDK.

Broadcom's first open source offering of the SDKLT is for BCM56960 Tomahawk switch, which is widely used in data center top-of-rack (TOR) switches. The SDKLT open source code is posted on GitHub. The open source code and the Logical Table APIs are released under Apache 2.0 license. The software is designed for High Availability (HA) including support for Soft Error Recovery, Warmboot, and In Service Upgrades.

“The SDKLT brings a fresh, state-of- the-art software development approach to the broader community of network software developers where they can now fully and directly control and monitor the rich switch feature set optimized for SDN and cloud use cases,” said Ram Velaga, senior vice president and general manager of switching products.
