#amd have just released a 32 bit #riscv #cpu - very #outoftheblue https://www.xilinx.com/products/design-t.. Apparently it is because they #purchased #xilinx and #microblaze is a 20 year old #architecture from them.
Seeing this I am now #tempted to #manufacture the #cpu we work on #internally https://www.righto.com/2023/02/8086-modr.. I would need to work out how many #components would be required... Maybe it brings no benefit to what we do?
Apperently the M2 #apple #silicon is pretty #battery #efficient https://youtube.com/watch?v=P0h8q6D0s74 It's great that there is someone else in the #cpu space, but terrible that it is #apple ...
#notetoself - this in an excellent #resource for #intel 8080 #cpu #chip #development #history https://baltazarstudios.com/webshare/A-Z.. This would be really useful for the #book I intend to write on the subject.
Pretty interesting. The #cpu #speculative #computing that #intel and #amd had *massive* #security #issues with recently seems to be #redundant with some better #designed #cpu #architecture that better handles some #edgecases https://www.cs.cmu.edu/afs/cs/academic/c.. This could be a way forward for both #companies , and potentially something for #arm to look at!
Okay, this is super cool: https://hackaday.io/project/180407-neotr.. As #raspberrypi #pico #motherboard that uses the #pico as a #cpu , with #vga #video output and #audio . Insanely cool!
Interesting, the #linux #kernel #scheduler could be getting an overhaul which tends to favour #cpu #cores that were used recently, rather than spin up #unused #cores https://www.tomshardware.com/news/nest-l.. In theory this should reduce switching #lag . Could be very cool!
Oh wow, #intel have been found with *another* #cpu #security #issue - this time one they can't #mitigate https://www.hertzbleed.com/ Apparently it works by purposefully causing your #cpu to #scale and increase the #clock to meet the #computing #demand . #intel #blocked the release of this #vulnerability .
The #quartz 64 and #soquartz #sbc 's by #pine 64 are really interesting, offering larger amounts of #ram , #cpu , #pice , #usb 3.0 and many other goodies: https://www.pine64.org/2022/05/31/may-up.. The one interesting thing I would like to see is the new #pinetime #update and the #pinesound #pinebuds - these projects are really cool.
Interesting #discussion on #lowendbox about what can be done of a #resource #limited #vps https://lowendbox.com/blog/what-can-you-.. I know there happens to be quite a lot! Especially as many of them, despite #ram #limits , have insanely good #cpu and #network #capabilities !
Hmm, #intel #purposefully acting very #shady by #crippling the #performance of #amd #cpu when using the #intel #compiler https://www.agner.org/forum/viewtopic.ph..
The new #apple M1 #ultra #cpu is #chunky - at 3x the size of the #ryzen #processor https://www.tomshardware.com/news/mac-st.. Apparently it has #ram under there too. Not looking good for #repairability ...
Looks like a *massive* #amd #zen #security #issue of the scale of #meltdown and #spectre is incoming: https://grsecurity.net/amd_branch_mispre.. Damn! It just keeps getting worse, it looks like no #cpu #manufacturer seems to be able to actually #design a working CPU...
Interesting #discussion about maximizing #ram #bandwidth https://unum.cloud/post/2022-01-29-ddr4/ As the #hackernews #comments point out, with a #amd #threadripper #cpu you need to have your code #numa aware: https://news.ycombinator.com/item?id=301.. This means delegating a task to a specific #core and #ram to minimize #throttling the #infinityfabric .
Heh #intel finally #releases a #cpu in a #laptop that has better #computation than #apple 's M1 Max: https://www.macworld.com/article/608396/.. #caveat : It's ludicrously #expensive , uses double the #power - and for all that only just about edges out the #competition ... In reality this is a massive loss for #intel . It shows they are incapable of competing currently...

Great to see the #pinetime gets #encryption for #communications ! This means it can be #trusted to do more important tasks. Also having a #shared #filesystem is massively cool! It's really a #shame that the #progress on the #pinecube has been so slow. No #update on a the #pinetab - I guess they #forgot they even have it as a #product / #project ? Anyway, looking forward to 2022!Regarding #pine 's latest #update https://www.pine64.org/2021/12/15/decemb.. For the #pinephone #modem #malware I wonder whether they couldn't pick up an active #attack by having a #markovmodel pick up on known #attack #sequences as a #temporary #workaround ... Tbe #pinedio looks interesting, even in the same #formfactor as the M5 #stack I #purchased recently. Maybe I will be able to #port my #software #efforts when it comes around! It's a shame it so far only supports #lora ...
