Resurrecting 1980s Computers

“You have to fight against being an antique.” – Burt Lancaster

Constant improvement brings constant obsolescence. When we keep updating our operating systems, processors, DRAM, and applications, we also leave behind the old apps and data that we used to use.

Normally, that’s not a huge problem. Most programs are backward-compatible with their predecessors. You can … Read More → "Resurrecting 1980s Computers"

Backward Balance Board

Sometimes we have to find a way around our design challenges. Sometimes finding the equilibrium between our design legacy and the futuristic stuff we want to do is harder than we we expected. In this week’s episode of Fish Fry, Nigel Forrester (Concurrent Technologies) joins us to discuss the ongoing security challenges in the world of embedded computing and how we can balance the past with the present … Read More → "Backward Balance Board"

The Art of (Rugged) Communication

In this week’s episode of Fish Fry, we are delving into the world of RFSoCs, radar, ruggedization, and reliability. Rodger Hosking (Pentek) joins us to discuss the details of the Zynq UltraScale+ RFSoC and we take a closer look at the benefits and challenges of this unique single-chip adaptable radio platform. Also this week, Justin Moll (Pixus Technologies) and I talk about how the various levels of ruggedization … Read More → "The Art of (Rugged) Communication"

Wheels Up!

In this week’s episode of Fish Fry, Scott Engle (Mercury Systems) and I investigate the coexistence of safety and security in world of avionics and why the key to security in aviation may be tied to the reclassification of security-related failures. Keeping with our aviation theme, we also take a closer look at how FORDISC (a windows-based interactive software program) may have just solved the mysterious disappearance of … Read More → "Wheels Up!"

I’d Like to Buy a Hint, Pat

“When one has taken root, one puts out branches.” – Jules Verne

What do microprocessors, pine trees, and public libraries all have in common? They have lots of branches. Branch instructions are fundamental to all von Neumann machines, along with arithmetic and logic operations. Without branches – specifically, conditional branches – you can’t really … Read More → "I’d Like to Buy a Hint, Pat"

Keep ‘Em Separated

Multicore processing takes center stage in this week’s episode of Fish Fry. Richard Jaenicke (Green Hills Software) and I discuss the challenges of multicore processing in avionics applications and how we can address multiple layers of safety certification on a software level. We also chat about the power of testing in avionics and and why you can’t mitigate multicore interference at the application level. Also this week, … Read More → "Keep ‘Em Separated"

I am sure you can't fail to have noticed that tomorrow is the 50th anniversary of the first landing on the moon. It has been everywhere for the last few weeks. I was a teenager. I remember... [[ Click on the title to access the full blog on the Cadence Community site. ]...

Let'€™s face it: We'€™re addicted to SRAM. It'€™s big, it'€™s power-hungry, but it'€™s fast. And no matter how much we complain about it, we still use it. Because we don'€™t have anything better in the mainstream yet. We'€™ve looked at attempts to improve conven...

High Speed Cable Product Technology   Today’s multi-gigabit high speed serial connections demand a new generation of cables and connectors. With PAM4 and speeds reaching 56 and 112 Gbps, older technology cannot deliver the signal integrity you need. In this episode of Chalk Talk, Amelia Dalton chats with Brian Niehoff from Samtec about keeping those eyes wide open with … Read More → "High Speed Cable Product Technology"
Designing High-Reliability Analog and Mixed-Signal ICs for Mission-Critical Applications  Designing products for reliability and longevity requires a different mindset – and a different tool set from the more common “just get it out the door” engineering methodology. We need to focus on all phases of product life, and do a diligent analysis of the mechanisms that can lead to premature failure in the … Read More → "Designing High-Reliability Analog and Mixed-Signal ICs for Mission-Critical Applications"
Mid-Board Optics: An Alternative to Pluggable MSA Solutions How would you like to upgrade from copper to optical flyover – all with the same connector system? In this episode of Chalk Talk, Amelia Dalton chats with Matthew Burns from Samtec about Firefly – a future-proof high-density flyover system.
