11 Reasons You Should NOT use an FPGA for a Design, and Four Reasons You Should

We write a lot about FPGAs here at EEJournal, with good reason, and you might get the impression that they’re the right solution to every design problem. They’re not.

Here’s a checklist to help keep you in the right path to successful design when considering FPGAs as a design alternative:

  1. If you … Read More → "11 Reasons You Should NOT use an FPGA for a Design, and Four Reasons You Should"

Adventures in Memory – Samsung’s HBM-PIM and A New Brain-Inspired Memory Device

In this week’s Fish Fry podcast, Nam Sung Kim (Senior Vice President of Samsung’s Memory Business Unit) joins me to discuss why he believes our computing architectures must evolve to meet the needs of artificial intelligence and machine learning applications and how breaking the traditional Von Neumann processor-memory boundary could be disruptive to both the hardware and software sides of our industry, and the details of Samsung’ … Read More → "Adventures in Memory – Samsung’s HBM-PIM and A New Brain-Inspired Memory Device"

Microchip Powers Down the Edge

Microchip’s FPGA offering has a heritage of low power and high reliability. Beginning with Actel’s antifuse- and flash-based devices that were picked up and advanced by Microsemi and then later joined Microchip’s formidable stable in a subsequent acquisition, the fundamental approach hasn’t changed – building the lowest-power mid-range FPGAs on the market.

Now, that agenda has advanced … Read More → "Microchip Powers Down the Edge"

Those two statements do seem in conflict, Karl Stevens. "FPGA is off by an order of magnitude in performance" is with respect to an ASIC. FPGAs exhibit superior performance when compared with processors running software. That's clearly stated in the parts of those sentences that you didn't quote, but I ...

Nothing wrong with testing your IP cores, metaprog.
Posted on Sep 21 at 9:35am by metaprog
Python in Pynq is for glueing things together and for testing your IP cores interactively. I don't see how it harms performance in those particular use cases (saying as someone who'd never use python for anything at all, but still like the design of Pynq).

Reason #8 Want to write code in Python? Go ahead ... BUT Python is a programming language that runs on computers by definition. It is a programming language, FPGAs do not run programs. EXCEPT a design can be implemented on an FPGA that runs programs. There are embedded processors that run programs, ...

In China, you can buy microcontrollers for three cents or less per chip. Is that really what Lattice is getting for it's least expensive FPGAs these days? If you're comparing a high-end MCU with a low-end FPGA, then consider the functions you're getting from both, for the price. Finally, all ...

The disappearance of a power supply module is regrettable, but there are plenty of alternatives. That's good because FPGAs need plenty of power supply alternatives.

FPGAs are for performance. Python is not. The "P" in "Pynq" stands for "Python." Pynq is a superlative learning tool for dipping your toe into FPGAs. That's why it was created in the first place. It is not intended for bare-metal FPGA programming (although you can do that on a ...

If you know you'll be producing products in the millions, you should be thinking ASIC from the start because the ASIC unit cost will be much lower than the FPGA. However, there's a high NRE cost on the front end of the product's life to design and fabricate that ASIC. ...

Flexible Power for a Smart World
Sponsored by Mouser Electronics and CUI Inc.
Safety, EMC compliance, your project schedule, and your BOM cost are all important factors when you are considering what power supply you will need for your next design. You also need to think about form factor, which capacitor will work best, and more. But if you’re not a power supply expert, this can get overwhelming in a hurry. In this episode of Chalk Talk, Amelia Dalton chats with Ron Stull from CUI Inc. about CUI PBO Single Output Board Mount AC-DC Power Supplies, what this ??ac/dc core brings to the table in terms of form factor, reliability and performance, and why this kind of solution may give you the flexibility you need to optimize your next design.
