i.MX Processor Hits 3,000 CoreMarks
NXP’s i.MX RT1050 is the fastest Cortex-M7-based processor. The company reused its i.MX 6ULL chassis, replacing the Cortex-A7 CPU but retaining most of the other subsystems.
New Gfast Silicon Joins Gigabit Class
At Broadband World Forum, Broadcom and Sckipio introduced new chips for Gfast Amendment 3, which boosts maximum download speeds to more than 1Gbps.
Arm Cooks Up Recipe for IoT Security
To help thwart hacker attacks and increase consumer confidence in IoT, Arm is proposing a set of industrywide specifications it calls the Platform Security Architecture (PSA).
Nephos Attacks Data-Center Switching
The MediaTek spinoff has delivered 100G Ethernet switch chips that scale to 6.4Tbps, challenging Broadcom’s Tomahawk 2.
Ryzen Marches Into Laptops
The first Ryzen Mobile processors, based on the Raven Ridge design, combine four Zen CPUs with a Vega GPU to deliver strong performance in ultrathin laptop PCs.
Centec Modernizes Enterprise Ethernet
Centec has optimized its new Duet2 Ethernet switch chip for next-generation enterprise designs, delivering high integration for multigigabit switching.
Epyc Benchmark Battle
Third-party testing shows that AMD’s new Epyc server chips offer strong competition to Intel’s Xeon Scalable Gold and even Platinum products, delivering similar or better performance at lower prices.
Lidar Points the Way for Self-Driving
Lidar is a critical component that will be required to deliver Level 4/5 autonomy. In these vehicles, advanced processors will fuse data from the lidar, radar, and image sensors.
GCT Combines Sigfox With NB-IoT
GCT Semiconductor’s new GDM7243i is the first single-chip modem to enable low-bit-rate IoT devices that operate on both Narrowband-LTE (NB-LTE) systems and the Sigfox low-power wide-area network (LPWAN).
MT6739 Switches Low-End GPU
MediaTek’s newest entry-level smartphone processor bumps up the CPU performance, switches to a PowerVR GPU, and adds camera and modem features to the popular MT6737.
Xilinx RFSoC Integrates Radio
The new UltraScale+ RFSoCs integrate high-performance ADCs and DACs for direct-RF sampling; they build on the shipping MPSoCs that already have ARM CPUs and programmable logic.
LX2160A Is NXP’s Biggest Multicore
Targeting high-end networking, the new LX2160A is the largest and fastest QorIQ processor, sporting 16 ARM Cortex-A72 CPUs, 100GbE, a 16-port Layer 2 switch, and PCI Express Gen4.
Ncore 3.0 Flexes Interface Chops
ArterisIP is continuing a steady pace of updates to its coherent network-on-a-chip (NoC) interconnect IP, adding Ace, Chi, and CCIX interoperability as well as optimizations that boost speed.
NetSpeed Applies AI to SoC Design
NetSpeed’s new Turing system uses machine-learning techniques to enhance the company’s network-on-a-chip (NoC) design tools, enabling them to better optimize the SoC interconnect.
UltraSoC Embeds Run-Time Analytics
UltraSoC’s IP includes traditional test-bench debug functions, but it also offers capabilities for in-field run-time data logging and reporting, performance optimization, and security monitoring.
