ARM inventor: Sophie Wilson (Part 1)

[@garyproffitt5941]

Very intelligent Sophie Wilson to replicate the ARM chips, amazing stuff.

[@paulanderson7796]

You're a legend, Sophie, in bringing computing to the world. Steve Furber is another such legend. Without ARM we'd not have the prevalence of mobile devices we see today.

​@Seniku Moonjewel Why do you care so much, what she identifies as or what name of honour she should get? Seriously, get a sense of proportion.

[@andrewstones2921]

I used to work for one the biggest Acorn dealers in the UK as a young engineer repairing the BBC Micros, I was sent on technical training courses to Acorn offices in Cambridge and on one occasion Sophie was there, not involved in any of the training but our instructor did tell us who Sophie was and I recall brief interaction. The BBC Micro was very well engineered and the technical documentation available to us was the best in the business, of course in those days we repaired computers to component level and the only part that was the exception was the power supply. They had a range of stock faults, most notable was the video chip which had heat issues especially on earlier versions, but they were far more reliable than most other micros of the time. It’s easy to forget that although we see the BBC MICRO as slow and low powered today, it was certainly not the case back then.

[@johnkunze5362]

This comment is directed to Sophie and Steve. I know you guys did all the work and I'm not trying to detract from that. I remember when Intel had basically screwed Motorola and had "won" the architecture battles of the day. I was head of r&d for Micro-RGS working on the 6809 and 68008. I developed on the Amiga until 86. Knowing intel had won, I gave up codeing. I put all my free $ into doing an end run around the x86 arch and that brought us to Arm. They can't stop us now. I'm back to codeing. I'm known as Mr. Arm around here. I remember spec ing universality of registers and pc offset branch and data. Wonderful implementation. Thanks. I now have in arm32, multiple stacks with ascending/descending, full and empty universal. Wow. Better than I want or needed. The extent to which the structure meets my needs is beyond anything I imagined. I have devoted my life to this work. Only arm32 can do the tasks I need. I did get my friends at softbank to get into control and blocked arm from US domination. I think I hold the rights now. I ❤️🥰🤗😇 you both and hope you will continue to support this cause. More later. Dr. John (ha)P. Kunze III. I hold over 52,000 patents and founded open source and the internet. To the betterment of mankind using creative computing.,jok

[@stanhristov]

Thank you Sophie Wilson. You deserve Nobel prize...

[@HPPalmtopTube]

Although I personally agree with her getting recognition for her work with for example a Nobel prize, I think that's impossible, as Nobel prizes are awarded to people who make considerable advancement to areas of science, by inventing or discovering something new, eg, if she had invented or created the very first micro-chip / integrated circuit, or, invented the RISC architecture, she would be eligible for a Nobel prize, but, in her case, she created a RISC microprocessor architecture, and all these concepts, technologies and inventions were already in existence and were actually invented by others before she created the ARM microprocessor architecture with her team-members... They did create a very, very technically efficient version of it though, and that definitely deserves massive recognition ;)

OMG. Eye opener. If you search through all the past catalogues you can find details (and a load of BS) on the real founders/developers and appreciate the genius in the original architecture. Absolute outstanding example on what can be produced under financial, personal determination and commercial constraints. I certainly can truly appreciate the brilliance in the early development of Arm core.... xxxxx

[@antonynewman3924]

Such an incredible instruction set. Pleasure to hear an interview with the inventor. AJ.

[@badpharma461]

The most elegant CPU design in history. The only flaw was not using branch-delay slots which yes, are not elegant but neither is the solutions used in later versions. MIPS is a close second and I am very fond of SH2 but ARM uses fewer instructions to complete a task, vital with nested loops.

According to a Google talk with the THUMB designer, Sophie's mistaken, it was Nintendo who looked at ARM but the 32bit set was too sparse and would inflate memory costs greatly. Nokia going with the unproven THUMB forced others to chose it too or risk much worse performance

[@gente21]

Excellent interview. I would recommend using a tripod though, I think that it would add a lot of value to your videos.

[@charbax]

This was filmed with my Panasonic GH3 which doesn't have sensor image stabilitation, now I use the Panasonic G9 which has IBIS stabilization with Dual IS 2 so films much smoother handheld but also I often use my Zhiyun Weebill S gimbal stabilizer for even more stability when filming. Sorry about the shakes in this one.

Since 2015, I still never use tripods, but now my newer Panasonic G9 films 4K60 with an amazing IBIS sensor stabilization technology, that looks great handheld, and for important videos I also have the amazing Zhiyun Weebill S gimbal to stabilize even more.. Sorry I should have brought a tripod for this interview, I tried to post stabilize using KZbin's stabilization option (which isn't available anymore) but that looked worse actually..

[@imrank340]

I worked on IBM 370 model 185 which 1024 mb ram with various accessories in the mid 1964, an IBM assembler uses R0 to R19 registers with Program Status word. Acorn/ARM very much copy of IBM mainframe 370, including some of instructions particularly for IPL, initial Program Load for JCL.

[@jaimeduncan6167]

It's unlikely. I am sure ARM contains ideas from the IBM 360/370. They are arguably the most influential architectures and implementations of all time. Even so ARM is a RISC machine the 360 is the definition of CISC with the good ( you could create low costs architectures back in the 60s and 70s when gates where expensive for example) and the bad (like problems with super-scalar execution). Back in the 80s with Apple influence and participation the RISC part was included in the name. Notice that one can discus the level of RISCness of the original desing, but we do know it was not built around direct memory access.

[@qo92]

Surely this is nonsense. Naming a bunch of registers R[0-15] is hardly 'very much a copy'. And as for the JCL instruction IPL, well do that have to do with the ARM? I'm sure Sophie and Steve drew their inspiration from a bunch of CPUs (6502, 32016, 68k etc) on what TO do and what NOT to do, but I would hazard a guess that not much inspiration was taken from the IBM 370 machine language instruction set.

I was thinking the same thing. He didn't recognise the Beeb, didn't really seem to know how significant her achievements have been (or what they were exactly), and didn't know who Herman was. She took it well though. Could see the look on her face a little though.

[@azzym8794]

I have been programming in Assembly as well as C etc since the eighties. To be honest, having used and familiar with TI's TMS9900, MCS51, Z80, Z8000 etc I find the instruction set of the ARM processor rather deficient and not too intelligent. If anything, it is marketing and not the intellectual content of this micro, which has won. Even the "lowly" MCS 8051 (according to AMR aficionados) is far superior in the design and choice of architecture. Even now I find that most embedded projects can be developed faster and more elegantly in chips like the Silicon Labs's C8051F120 @ 100 MHz clock. Only some projects which need a lot of flash face a bottleneck, which can be resolved with memory cards etc. No wonder it (ie., MCS8051) just wont go away. Its ability to handle difficult tasks is amazing. Besides the lack of diversity itself is worrisome.

[@azzym8794]

*+Andrea* Do you know how many instructions a 32 bit word can encode? I can push a set of registers on the stack or anywhere else just as easy as pushing with a single instruction. What is better is I have a choice of which registers to save. The elegance of the bit variables is another thing I like; aliasing, as used by the Arm lacks the beauty. I actually write embedded code for the nasty machines that whizz by at supersonic speeds for a living. My experience is that the older 8 bit are easier to handle with much less debugging needed. I use Folders routines extensively for floating point work. It might just be my own experience.Not a universal fact. I grant. In any case, for me at least, there is no need to go gaga over ARM. I had to learn a whole bag of new tricks to use the ARM. I did not think the gain in processing power was worth the aggravation.

[@worldgeektube]

The ARM design was not engineered to be elegant or particularly easy to program in assembler. The intention was to make a high performance CPU/RAM combination which could be produced cheaply. It should give high level language performance similar to hand written assembly on the other CPUs of the era.

[@worldgeektube]

At the time they were thinking of home computers which would be programmed in interpreted or compiled by languages. The genius of ARM was in the tiny team who had extraordinary knowledge of how CPUs were actually used and how to reduce implementation complexity and cost.

[@jaimeduncan6167]

Azzy M You know that your user case is marginal (important but marginal). Many of those clever ideas affect multitasking or superscalar operation (more often this one). I am not saying that you are wrong, but clearly the 8 bit processors don't have the architecture to handle modern programing or performance in an elegant way. You will need to program a new VM to run on top of the 8 bit architecture if you want to succeed in a reasonable time-frame

[@tesakun3133]
