I need to admit that I’m beginning to really feel like an previous idiot, however the place are we going to seek out one presently of the day (these are the jokes The Muppet Present refused)? I used to be simply recalling the traditional The Instances They Are A-Changin’ track by Bob Dylan and considering how true this sentiment is, particularly in the case of expertise. I’m additionally reminded of the traditional Greek thinker Heraclitus, who famously famous, “The one fixed in life is change” (I’m undecided if that is repudiated or complemented by that thinker of our instances, Jon Bon Jovi, who noticed, “The extra issues change the extra they keep the identical”).
As an apart, a couple of weeks in the past I learn Bob Dylan’s memoir, Chronicles: Quantity One, which offers a deep and interesting perception into his origin story. It was right here I found that he was born Robert Allen Zimmerman—he chosen his stage identify as a mix of Bob, quick for Robert, and Dylan after the Welsh poet and author, Dylan Thomas. However we digress…
Additionally, I not too long ago watched an excellent movie known as The Man Who Invented Christmas. It is a unusual type of biographical comedy-drama that in some way works magnificently (a lot in order that I simply ordered a DVD to be delivered to my pricey previous mother in England for her to observe over Christmas). It’s about Charles Dickins and his writing of A Christmas Carol. Along with being an superior film appropriate for youths of all ages (from 8 to 80+), I realized all types of issues about Charles himself, akin to the actual fact he spent two years in a workhouse beginning on the age of 12 when his father was dedicated to a debtor’s jail.
The explanation I point out all that is that it’s round this time of 12 months I discover myself cogitating and ruminating on the technological ghosts of Christmas previous, current, and future (and if that’s not a segue to recollect, I don’t know what’s LOL).
Once I discuss to youthful people concerning the applied sciences we had once I was a child, they have a look at me with vast eyes brimming with disbelief. Surprisingly, the three little women who dwell subsequent door exhibited no skepticism in anyway once I knowledgeable them that one among my chores once I was their age was to shoo the dinosaurs out of our household’s cabbage patch (that is clearly a joke as a result of my household by no means owned a cabbage patch).
I’m a science fiction fan. I keep in mind watching the primary episode of Physician Who, An Unearthly Youngster, which was transmitted at 5:16 p.m. on Saturday November 23, 1963. I used to be solely 6 years previous, however I keep in mind it prefer it was yesterday (which isn’t saying a lot as a result of I don’t keep in mind what occurred yesterday). The primary notes of the theme music knowledgeable me that this was a program that might be finest watched from the protection discovered behind the couch. This was the primary digital music I’d ever heard. Previous to that, each TV program was accompanied by orchestral compositions.
As one other apart, I as soon as met Nick Martin who hails from Down Beneath. Nick was the founding father of the EDA firm Protel Methods, which developed into the purveyor of PCB design software program, Altium, we all know and love as we speak. We have been chatting at an Embedded Methods Convention (ESC). It seems that Nick began watching Physician Who from behind his guardian’s couch. “Nice minds suppose alike,” as they are saying. In fact, in addition they say, “Fools seldom differ,” however I’m certain that doesn’t apply to us.
I’m sorry. What have been we speaking about? Oh sure, televisions once I was a lad. Ours concerned a really small display screen in a really massive and heavy cupboard that dominated the room, presenting its low-resolution eye sweet in superb black-and-white. If somebody at the moment had described a future involving 65-in. (and up) flat, excessive decision, COLOR televisions in many of the rooms in a home, I might have thought we have been speaking a few timeframe paying homage to Buck Rogers within the twenty fifth Century. And but, right here we’re.
Once I discuss to youthful engineers concerning the instruments and applied sciences obtainable once I was beginning out, I can see the disbelief of their eyes. I hail from these days of yore when 7400-Sequence TTL and 4000-Sequence CMOS units containing only some handfuls of logic gates have been thought of to be cutting-edge. I additionally watched as early microprocessors—just like the 8080, 6502, and Z80—appeared on the scene, accompanied by single board computer systems (SBCs) that employed these units, just like the KIM-1, for instance. Following its launch in 1976 and all through the rest of the Seventies, I drooled with want at any time when I noticed an advert in an electronics journal for a KIM-1, however I used to be an impoverished scholar, and this magnificence was properly past my meager means.
I’m tempted to speak about applied sciences like chiplets, however I wrote about them not too long ago (see Cheeky Chiplets Meet Tremendous NoCs). Issues are shifting extraordinarily shortly on this area. Since that column, which dates from solely a few months in the past, a brand new participant—Zero ASIC—has leapt onto the middle of the stage with a fanfare of sarrusophones (as soon as heard, by no means forgotten).
I’m additionally tempted to speak about applied sciences like using Generative AI (GenAI) for software program and {hardware} design, however I lined these subjects a couple of weeks in the past (see Really feel the Flux!). At the moment, on the {hardware} entrance, GenAI was getting used solely within the context of PCBs. Since then, I’ve seen bulletins from EDA corporations like Cadence and Siemens speaking about utilizing GenAI within the context of ASIC and SoC designs.
Finally, I made a decision to stay with one thing that’s near my coronary heart—microcontroller items (MCUs). I keep in mind the arrival of the 8-bit Intel MCS-51, which is extra generally often known as the 8051. Launched in 1981, this little rascal has now offered in billions of items. I knew the creator of the 8051’s structure—John Wharton (RIP). He as soon as advised me that, as a younger engineer, he used to lunch with one among his supervisors. Someday, this supervisor advised John of a lunchtime assembly at which free sandwiches have been to be served, so that they each snuck in. It turned out this was the kick-off assembly for Intel’s newest and biggest microcontroller, whose structure at the moment was undefined. Following that assembly, John returned to his desk and sketched out the structure that turned the Intel 8051.
John handed in 2018. I want he have been nonetheless right here so I might chat with him about some new MCUs that have been not too long ago introduced by an organization known as Alif Semiconductor.
Ensemble MCU (Supply: Alif Semiconductor)
Bodily, these units are tiny, however processing-wise… oh my goodness gracious me. The Ensemble household ranges from a single 32-bit processor with an optionally available micro neural processing unit (microNPU), to 4 32-bit processors and two microNPUs. Along with on-die graphics imaging (GPU, MIPI-DSI, MIPI-CSI) and an on-die safe enclave, these little scamps additionally function as much as 13.5 MB of on-die SRAM and as much as 5.75 MB of on-die NVM (within the type of MRAM).

As in comparison with conventional MCUs, Ensemble units are claimed to offer two orders of magnitude extra efficiency whereas consuming two orders of magnitude much less energy. What all this implies is that these bodacious beauties can be utilized to carry out edge-IoT duties like object detection, akin to understanding which portion of a picture is a human face, for instance. This isn’t the form of factor you’ll take into account trying with a standard MCU, however it may be realized utilizing solely a mid-range Ensemble MCU. Moreover, it may be achieved with out the necessity for exterior reminiscence, energy administration, or further safety units. “Wowzers!” is all I can say.
As I’ve talked about earlier than, once I designed my first ASIC circa 1980, this was on the 5-micron expertise node. Right this moment, some corporations like Apple are deploying chips applied on the 3-nm (three-nanometer) node, TSMC’s forthcoming 2-nm node is predicted to seem available on the market circa 2025/2026, and the 1-nm node is tentatively scheduled for 2028.
Are you able to think about what MCUs shall be able to circa 2030? My head is spinning considering the probabilities. I believe it’s time for me to take one other dried frog capsule (or three). What about you? What do you concentrate on all of this?
