Divirtiéndome un poco con la tarjeta #Amiba2 de @Intescmx . Me gusta mucho esta tarjeta por que tiene un ft2232 y un #FPGA spartan6 con unos poderosos 9K LEs. Suficiente para aún pequeño SoC RiscV.

Made a PCB for my experimental analog platform to connect a SPI DAC to the FPGA with 8 analog outputs into the crosspoint switch fabric. Just waiting on parts to arrive today before populating. A set of differencing opamps will take the 2.5V internal reference of the DAC, and subtract it from each output to have a -2.5V to 2.5V swing Intending this to be for slow DC coupled control voltage outputs that can be routed/switched by the crosspoints into other modules plugged into the board to set initial conditions, comparator thresholds, etc

Custom made JTAG adapter is working on the ultra cheap alibaba Ultrascale I added a board to openFPGAloader, and created a spiOverJtag bitstream for the package to allow it to access the SPI flash (32MB MX25U25645G) I soldered a pin strip onto an unpopulated connector next to JTAG to see if I can find the pads and repurpose those signals as a UART connected to the second channel of the FT2232. DAC SFP cable connected to a 10GbE switch to see if we can get liteeth and etherbone going on this thing.

Awesome!

'Cyberpunk Edgerunners' SEASON 2 NEW INFORMATION: - If you cried watching season 1, you will cry more. - More violent and bloody. - Darker and more realistic. - Made by Studio TRIGGER - New Director, Character Designer & people that are "Hungry" with a different vision.

I’ve always wondered, why can’t we run CPU’s hotter? Look at any modern CPU, and the maximum junction temperature (TJMax) is around 95ish C. Leakage current explodes past that point, and reliability drops off a cliff. But the question is…couldn’t you make a “tougher” transistor? The answer is…sorta. The Glenn research center at NASA experiments with silicon carbide wafers. Venus is crazy hot (~470C!). Apparently, NASA has been somewhat successful running a medium-scale IC at 500C for 1 year. Ozark IC also won a contract to develop a multicore RISC-V cpu intended to operate at 500C, but I haven’t seen updates in a while. Perhaps an EE can chime in. Is ~95C TJMax just a local optimum that everyone collectively settled on? How much density would you have to give up to run things just a little bit hotter? I wonder if a special, “low density space H100” could reliably run at say, ~150C, or if that’s completely outside the realm of what’s feasible.

Llegó la décima! 😍🥲

Before #AI acceleration became a priority, #FPGAs changed computing by making hardware reprogrammable after manufacturing. Now an @IEEEorg Milestone, they enabled faster innovation in #networking, modern AI systems, and beyond. Learn more at @IEEESpectrum: bit.ly/IEEESpectrum-FPGAs

Bye bye @AMD

Lisa Su (CEO of AMD) unveils the world's smallest AI development PC, capable of running 200B parameter models locally.

Por esga pelicula me interese en las telecomunicaciones.

For the last few weeks, I've been writing a multi-CPU single-board computer like explorer. I'm calling it CROSSWOZ (Hat tip to Woz and the WOZMON). Seven vintage CPU cores (6502, 65C02, Z80, 8080, 8085, 6809, 1802) share a 64K memory bus and the same WOZMON-style monitor. I can swap CPUs in place. It's got a mini-assembler per CPU, JMON-style debug, and animated paper-tape I/O. I'm pretty pleased with how it's turning out.

You can't engineer luck. Cleanest phrasing of P vs NP I've heard. NP is the magical computer that always tells you which path to take. P is what current silicon can do. Tetris is NP-complete. Chess is EXP-complete. MIT 6.006 Introduction to Algorithms, Fall 2011.

AMD's legendary K5, its first independently-designed processor, is being removed from the Linux kernel — 4.3-million-transistor chip gets the axe because it lacks Time Stamp Counter (TSC) support, making it a coding burden tomshardware.com/software/li…
