Intel Finally Launches Sapphire Rapids: It’s All About The Accelerators, Baby

After many delays, Intel has finally launched the long-awaited Sapphire Rapids family of server processors, now named the 4th Generation Intel Xeon Scalable processors and the Intel Xeon CPU Max Series. Both names are mouthfuls, which has become typical of Intel product naming. Also typical is Intel’s ability to change the playing field to its advantage. Here, … Read More → "Intel Finally Launches Sapphire Rapids: It’s All About The Accelerators, Baby"

NASA Recruits Microchip, SiFive, and RISC-V to Develop 12-Core Processor SoC for Autonomous Space Missions

NASA’s JPL (Jet Propulsion Lab) has selected Microchip to design and manufacture the multi-core High Performance Spaceflight Computer (HPSC) microprocessor SoC based on eight RISC-V X280 cores from SiFive with vector-processing instruction extensions organized into two clusters, with four additional RISC-V cores added for general-purpose computing. The project’s operational goal is to develop “flight computing technology that will provide at least 100 times the computational … Read More → "NASA Recruits Microchip, SiFive, and RISC-V to Develop 12-Core Processor SoC for Autonomous Space Missions"

RISC-V Foundation’s Chairman says: “All Your Cores Are Belong to Us”

When RISC-V International’s chairman of the board Krste Asanović took the stage to report on the state of the RISC-V union at last month’s RISC-V Summit, he mouthed the phrase that’s always said by the president of the United States when reporting the country’s state of the union: “The state of the union is strong.” Later in his talk, Asanović said the same thing, but in a much more assertive way: “All your cores are belong to us.” … Read More → "RISC-V Foundation’s Chairman says: “All Your Cores Are Belong to Us”"

Automotive Electronic Seat Control

Sponsored by Infineon

Today’s automotive seat design must keep in mind size, cost, battery life and passing EMC testing. In this episode of Chalk Talk, Amelia Dalton and Rick Browarski from Infineon investigate the newest innovations in automotive electronic seat control. They take a closer look at the anatomy of power seats today, the role that an ECU plays in the control of electronic seats and how Infineon chip set offerings can help you with your next smart power seat design.

Hi, Johnny. You wrote "The pleasure of pure digital design." Amen. And if I remember correctly , adding 1's Complement with a "Hot 1" into low order position does a subtract and has been used in computers. Here is an evolving "source syntax" that I think is easy to parse using C#; ...

Tra-laaaaa!!!! What a great high performance work-out with implementing fixed point arithmetic. Kudos Max and I now know why you are "Max the Magnificent". Karnough Mapping (https://www.geeksforgeeks.org/introduction-of-k-map-karnaugh-map/) is one additional approach to add for the solution to the black-box problem.

Well done! For your next act, how about some logic blocks? Such as the TTL in the TI yellow book. Then microprogrammed controls would be fun. This nonsense of using a description rather than logic for design entry has to end. Some languages have recently added conditional assignment statements and ...

I think you are referring to ‘implicit inversions’ as a software construct? In the case of inverting a signal (something that is hardly ever done in an event driven system like Flowpro) the solution is a test (decision) circuit construct, two action constructs and a storage construct. Not very efficient ...
