Synopsys' Taylor Armerding warns that critical infrastructure is still vulnerable to cyber threats, with Kaspersky finding that 42.7% of the industrial control system computers it protected last year were attacked by malware, email phishing, or other threats. Cadence's Paul McLellan listens in as Jon Masters of Red Hat considers how to tackle speculative execution and branch prediction vulne... » read more

Week In Review: Design, Low Power
By Jesse Allen - 17 May, 2019 - Comments: 0

Tools & IP Cadence introduced the Tensilica Vision Q7 DSP, which provides up to 1.82 TOPS and is specifically optimized for simultaneous localization and mapping (SLAM). The DSP has a very long instruction word (VLIW) SIMD architecture, an enhanced instruction set supporting 8/16/32-bit data types and optional VFPU support for single and half precision, and a number of iDMA enhancements in... » read more

Can The Hardware Supply Chain Remain Secure?
By Andy Patrizio - 15 May, 2019 - Comments: 2

Malware in computers has been a reality since the 1990s, but lately the focus has shifted to hardware. So far, the semiconductor industry has been lucky because well-publicized threats were either limited or unproven. But sooner or later, luck runs out. Last year saw two significant incidents that shook people’s faith in the integrity of hardware security. The first was the Meltdown/Spectr... » read more

Cadence's Sean Dart shares an example of the kind of optimizations HLS tools can perform that would be difficult to find and implement by hand-coding RTL. Synopsys' Taylor Armerding takes a look at three cybersecurity initiatives from the U.S. government, from an IoT bill to improved voting machines, and whether they're likely to work. In a video, Mentor's Colin Walls points to why flashi... » read more

Multiple Roots Of Trust And Isolation: Key Roles For Absolute Security
By Ben Levine - 13 May, 2019 - Comments: 0

Today, there are many different security processors available to the SoC designer. A majority have a commonality, and that is they are based on the same architecture. You can call it a two-domain architecture. One is non-secure; the other is secure with a single bit dividing the secure from the non-secure. What’s more, different applications from different entities may be running in that o... » read more

Engineering The Signal For GDDR6
By Shawn Nikoukary - 09 May, 2019 - Comments: 0

DDR1 through DDR3 had their challenges, but speeds were below one gigabit and signal integrity (SI) challenges were more centered around static timing and running pseudo random binary sequence (PRBS) simulations. Now, with GDDR6, we are working on 16 to 20 gigabits per second (Gbps) signaling and even faster in the near future. As a result, engineering the signal for GDDR6 will require careful ... » read more

Latency Under Load: HBM2 vs. GDDR6
By Ed Sperling - 09 May, 2019 - Comments: 0

Steven Woo, Rambus fellow and distinguished inventor, explains why data traffic and bandwidth are critical to choosing the type of DRAM, options for improving traffic flow in different memory types, and how this works with multiple memory types.   Related Video GDDR6 - HBM2 Tradeoffs Why designers choose one memory type over another. Applications for each were clearly delineate... » read more
