Congratulations to our very own Simon Robinson for receiving an Excellence in Learning and Teaching award in yesterdays graduation ceremony

Simon is one of four #ComputerScience recipients to have received a 2022 ELTA - congrats also to Shane Fleming, Neal Harman & @DrSeanWalton

[Sean Walton @DrSeanWalton]

Thanks so much to all the students that nominated me for this and all the colleagues who supported me over the past two long and difficult years really means a lot! And congrats to CS peeps @0x0000002a, @DelightfulApps (Simon :p) and Neal for their well deserved awards!

[Steve Leibson @steveleibson]

Welcoming a new entrant into the FPGA market: Renesas. The company just announced that they plan to make teeny, tiny FPGAs on the order of 1000-2000 gates, and sell them for less than 50 cents each in volume.

Happy 50th Birthday 4004 microchip! You’ve made so much possible over the past half-century.

[Sean Walton @DrSeanWalton]

well I just started to record a video tutorial for my module, got 15 minutes in and just couldn't do it anymore...

...at least it didn't happen in a live lecture. I can't ever remember being this tired and hearing so many colleagues say the same.

@DrBenEvans Thanks for organising, it was super exciting!

[George A Constantinides @gconstantinides]

High-level synthesis for #FPGA using probabilities to model dynamic control-flow environments. A preview of @jianyi_cheng’s work he’ll be presenting at #FCCM2021 next week (joint work with @wicko3 and me)

Enjoying Marta Kwiatowska’s @bcs Lovelace Lecture. Really nice tour through the PRISM probabilistic model checker and its many applications. Tune into @jianyi_cheng ’s talk at #FCCM2021 for yet another one: optimizing dynamically-scheduled FPGA hardware!

Things are heating up in the final CSC368/M68 lab, where students have to make their TinyPico temperature sensor transmit temperature data payloads to the central server while consuming as little energy as possible.

[Shane Fleming @0x0000002a]

@ThomasVarnish @MIT @mit_nse Congratulations!! This is such wonderful news :)

[Shane Fleming @0x0000002a]

In tomorrows lecture, I'll be live demonstrating how ping flooding a Linux based embedded system can cause substantial latency spikes. We will be comparing this to an ESP32 running a real-time operating system, where the same attack barely affects it.

[Satnam Singh @satnam6502]

I've just been appointed as a teaching lecturer at UC Santa Cruz for the spring quarter of this year. Students, get ready to learn Verilog hardware design Satnam-style!

[Jianyi Cheng @jianyi_cheng]

Feeding the code into Vitis HLS is problematic for HLS tool designers like me when transforming LLVM IR back to C code, including pragmas. The new Vitis HLS front-end has significantly helped integrate our tool DASS into the HLS flow.

[Jianyi Cheng @jianyi_cheng]

Our paper (me, @0x0000002a, Joy Chen, Jason Anderson, @wicko3 and @gconstantinides) "Efficient Memory Arbitration in High-Level Synthesis from Multi-threaded Code" has been accepted by IEEE Trans. on Computers. Preprint to follow.

[Shane Fleming @0x0000002a]

@kouris_a Congratulations Alex!

[Shane Fleming @0x0000002a]

The biggest challenge was handling some students code sending WebSocket messages as fast as the little TinyPico could. This would effectively bring the entire WiFi network grinding to a halt. It's amazing how very few (say 2 or 3) misbehaving devices can have such a big impact!

[Shane Fleming @0x0000002a]

Blinking an LED is such an important part of getting started with embedded systems. Unfortunately, students in my class weren't able to physically attend, so we used the built-in WiFi of our TinyPicos to make some virtual LEDs, dance, speak, and blink.

@jianyi_cheng @gconstantinides @wicko3 Congratulations! Wonderful news.

@MPorcheron Thanks Martin :)
