Centriq Is the King of Cache
Qualcomm’s new Centriq 2400 processor has 72MB of combined L2/L3 cache, more than the largest Xeon, and adds six DRAM channels and plenty of PCI Express.
Imagination Adds Neural-Network IP
Imagination has joined a crowded field in the deep-learning-accelerator market by offering its PowerVR 2NX core, which provides flexible bit widths and an integrated MMU.
RISC-V U54 Runs Linux
SiFive’s newest CPU, the Coreplex U54, is the company’s first with an FPU and first with an MMU, enabling it to run Linux and similar operating systems for low-cost embedded applications.
Cypress Blends WICED, 28nm ULP
Cypress Semiconductor’s new 28nm wireless-combo MCU supports most 802.11ac Wi-Fi features plus Bluetooth 5. It can offload host-CPU workloads for sensor processing and streaming audio.
NXP Drives DSRC for Connected Cars
The SAF5400 is NXP’s second-generation modem for dedicated short-range communications (DSRC), a system that enables vehicles to communicate with each other (V2V).
Silexica’s Hardware/Software Co-design
Silexica offers performance-analysis tools that help system designers optimize their hardware and software for throughput, power consumption, memory usage, or cost.
Inphi PAM4 PHY Aims at Systems
Inphi is reentering the system-side-PHY market with Vega, a 400Gbps PAM4 device for front-panel and backplane applications that span 50G, 100G, 200G, and 400G Ethernet rates.
Kalray Rethinks Parallel Processing
Kalray’s third-generation “Coolidge” processors will have up to 160 general-purpose compute cores plus security, machine-learning, and computer-vision coprocessors.
PowerVR Series9 Starts at Low End
Imagination has delivered the PowerVR Series9XE and Series9XM GPU IP cores for applications requiring area-efficient performance and low power consumption.
Helio P30 Boosts Camera, Battery Life
MediaTek’s newest midrange smartphone processors upgrade the Helio P20 with a Mali G71 GPU, a vision processor, improved camera capabilities, and lower power.
Qualcomm’s Falkor Targets Servers
Falkor is the brains of the new Centriq 2400 server processor, which is set for production by the end of this year. The ARMv8-compatible CPU can decode four instructions per cycle.
Threadripper Tops Multithread Tests
Our benchmark testing showed AMD’s Threadripper scores well on high thread-count applications, but it lags Intel’s high-end Core i9 processor on most other workloads.
AImotive Accelerates Deep Learning
Known for its ADAS software, AImotive has introduced licensable hardware IP to accelerate neural-network algorithms with performance of up to 5 trillion MAC/s.
Intel 8th Gen Spans Architectures
Although the first 8th generation Core processors for laptops use Kaby Lake R, other models will use six-core Coffee Lake designs for desktop PCs and even 10nm Cannonlake designs.
Kandou 500Gbps Serdes IP Targets 2.5D
Kandou’s new 16nm Glasswing hard macro enables 500Gbps interfaces between die in a 2.5D package. The IP core implements the company’s unique protocol for 5-bit over 6-wire signaling.
