A new path to generating optical frequency combs, developed by a team from the University of Maryland (UMD), resulted in a nested comb-within-a-comb that could lead to smaller, more efficient frequency combs for atomic clocks, rangefinders, quantum sensors, and other applications that require precise measurement of light. #photonics #PhotonicsSpectra

November 2024 Feature Paper #2 Brought to you by IEEE Open Journal of Vehicular Technology AI for beam management is a critical focus at the physical layer design of 3GPP release 19. To ensure quality, AI model management includes monitoring predictions against legacy results and adapting models based on user equipment (UE) location and speed. Enhancing model performance can reduce fallback to traditional methods. The article - AI-Based Beam Management in 3GPP: Optimizing Data Collection Time Window for Temporal Beam Prediction - coauthored by Yingshuang Bai, Jiawei Zhang, CHEN SUN, Le Zhao, Haojin Li, and Xiaoxue Wang - proposes adjusting the data collection window size based on UE speed to optimize AI performance for moving UEs. https://lnkd.in/exQDNvUn We hope that the short summary of this feature article written in layman language may make your reading a pleasure! #ieee #ieeevts #journal #openjournal #ai #artificalintelligence #3gpp IEEE Vehicular Technology Society

In the last post I wrote about how the authors of “The RISC-V Reader” posed the BCD (Binary Coded Decimal) operations of the x86 as a mistake of the past. I countered this supposition and argued that it is a useful feature for certain applications. But I didn't want to leave the reader with the impression that I thought that there were no features that I would regard as design mistakes. That is certainly not the case. The 8051 was an early design by Intel and was copied by many other manufacturers. It has features that are truly design mistakes that should never have happened. It is an architecture which should have been left to die an early death but was perpetuated by hardware people who are deficient in their software capabilities. One of its design mistakes is its upward-growing stack. What this does is to reverse the order of the bytes so that they don't appear like they should in memory. They are useless as local variables. Advanced programming languages like C heavily use variables stored in the stack for active temporary storage. But because of the deficiency of the 8051's stack-relative address modes, it is a moot point. It is akin to a blind person finding himself without binoculars when they would be useful for identifying birds for example. The Motorola HC08 has a downward-growing stack and it has good stack relative addressing modes. But even this architecture has a minor design mistake. It uses post-decrement instead of pre-decrement for pushes and pre-increment instead of post-increment for pulls. This flaw was corrected in the HC12. But Motorola decided to keep the flaw in the HC08 to maintain software compatibility. All-in-all, the HC08 is still far superior to the 8051. The x86 got it right when it comes to push and pull stack operations. Intel just used the wrong key word for "pull". RISC-V doesn't have built-in push and pull operations. It is a raw primitive architecture like IBM's mainframes. #Intel8051 #ISA #assembly #programming #computers #microcontrollers
