Dave Jaggar recounts the history of the ARM architecture, detailing how Acorn's challenges led to the creation of Thumb, StrongARM, and modern mobile processors.
Dave discusses the novel and inspiring career that led to the ARM architecture which effectively powers the digital world, being the reason that your phone is small and doesn't burn a hole in your pocket. In the late 1980’s Acorn, a British one-hit-wonder computer company, faced imminent extinction, with its only assets being 18 months of life support rations and perhaps the worst microprocessor ever designed. What they did right was to hire Dave Jaggar, with the ink still wet on his master's thesis. Over eight years Dave systematically defined the entire ARM architecture, enabling it to be a popular embedded controller for the digital revolution, with around 100 billion units shipped. As ARM’s Head of Architecture Design, Dave authored the ARM Architectural Reference Manual and is the Founding Director of the ARM Austin Design Center. Get the book here: goo.gle/2Xiheya.

On “Was Acorn's RISC OS an under-appreciated pearl of OS design?”
Agreed plus Thumb which got ARM into Nokia mobile phones. Dave Jaggar has some interesting comments on the history around DEC, StrongARM and the Austin ARM team. link to this video

On “Was Acorn's RISC OS an under-appreciated pearl of OS design?”
Surprising but true! Dave Jaggar makes it clear in this video that it was to keep code within smaller Nintendo ROM size constraints. Seven year gap between ARM / Nintendo discussions and GBA appearance! link to this video

On “ESP32-C3 WiFi and BLE RISC-V processor is pin-to-pin compatible with ESP8266”
That's one opinion. Another ARM engineer who contributed one heck of a lot more to ARM's success (designed ARM7TDMI, Thumb, Thumb2) says RISC-V is great. See at 51 minutes in this link to this video

On “Apple M1 foreshadows Rise of RISC-V”
Who says RISC-V is mediocre? Here's the opinion of probably THE most important ARM engineer of the 1990s and 2000s, Dave Jaggar who developed the ARM7TDMI, Thumb, Thumb2. link to this video Check at 51:30 where he says "Are there any ARM snipers? No .. I would Google RISC-V and find out all about it. They've done a fine instruction set, a fine job ... it's the state of the art now for 32-bit general purpose instruction sets. And it's got the 16-bit compressed stuff. So, yeah, learning about that, you're learning from the best."

On “RISC-V isn't as interesting as you think”
There's really a lot of severely misinformed opinion there. "Much of the hype of RISC-V is hoping for laptop/desktop/server class silicon." Really? RISC-V is pitched mostly against the likes of ARM, which seems to be doing fine without laptop/desktop/server class silicon. Several RISC-V vendors are already shipping Cortex A53/A55 class CPUs, which are used as the LITTLE cores in mobile devices -- and even still the main cores in lower end mobile. Several RISC-V vendors have formally announced A72 (SiFive U84) or A73 (Alibaba C910) class cores. Alibaba is apparently using these internally already, and boards for general sale are expected this year. SiFive's U84 will probably be shipping in ar…

On “RISC-V isn’t as interesting as you think”
> RISC-V seems like it hasn’t learned anything from CPUs designed after 1991. Never mind what RISC-V says about itself. Here is Dave Jaggar, a key ARM architect, endorsing RISC-V as state of the art in 2019: link to this video .

On “A history of ARM, part 1: Building the first chip”
Apple's investment in ARM in November 1990 (when ARM was spun out of Acorn as a joint venture between Acorn, Apple, and VLSI) was a result of Apple's decision to select ARM for the Newton sometime in 1990 since Acorn and Apple competed in the UK education market 1. 1 link to this video , "A History of The ARM Microprocessor"
