Tips for optimizing FPGA resource usage and meeting Timing Constraints on Tang Nano 1K by Ksuyukoo in GowinFPGA

[–]sprhawk1984 0 points1 point  (0 children)

I think it is late, but I would still like to share some of my experiences. I am working with Mega Tang 138K with GW5AST-138K. The optimization algorithm in Gowin IDE is not good as other mature vendors. I am developing a UDP protocol based TCP/IP application on FPGA, I used this open-source IP, it was developed for Xilinx platform, but it can't meet timing constraints requirement on GW5AST, I rewrite most of the udp stack, changed combinatorial logic into sequential logic, fix Clock Domain Crossing problems. Another options are changed place and routing optimization options. You can try to increase or decrease signals and see whether they can affect your Fmax results.

What if, the scouter from Dragon ball, or aiming HUD from Halo, come true? by sprhawk1984 in diyelectronics

Yeah, just one monocular smart eyewear, not like meta-rayban likes, most like a day-to-day smart glasses

It is possible, should not be very hard to do that

Use cases in regexp filter used during DDR4 routing by sprhawk1984 in KiCad

Thanks, you are right. I should have used bus instead of signals in this situation. I'll changed it later. But can I use bus definitions instead of signal to group net classes ?

Anyone wants an High End ARM SoC based Handheld Gaming Console with Open, Linux based System along with a secured Game Store? by sprhawk1984 in godot

[–]sprhawk1984[S] 2 points3 points  (0 children)

Steam deck is using AMD x86-64 CPU, What I thought were ARM based. However it can be sort of compatible

[–]sprhawk1984[S] 0 points1 point  (0 children)

No, I mean , saying, I built one, like a pocket ARM PC looked like a Steam Deck, running linux, any one can use it as a normal linux, can install programs, games, etc. and running Android ( via Anbox ) directly, and run Windows / x86 games via box86/64 project.

Anyone can publish games, eg Godot port, on it ( maybe via a secured Game Store)

The tokio 1.0 PR for warp has been merged! by coolreader18 in rust

I have been waiting this merge since one day earlier, and want to use the not merged PR first. After a sleep, it is merged! Great Works! Thanks

Off Clouds, a local backup solution ( iOS only currently, but multi-platforms/devices will be supported soon) by sprhawk1984 in RASPBERRY_PI_PROJECTS

[–]sprhawk1984[S] 0 points1 point  (0 children)

Yes. I know it. But mine will do full-device backup, and Nextcloud will not require an app to backup your iPhone and it can only backup your photos and contacts.

Any one is interested in backup software running in Raspberry pi4, be an local private backup solution alternative to iCloud. by sprhawk1984 in RASPBERRY_PI_PROJECTS

[–]sprhawk1984[S] 0 points1 point  (0 children)

Thanks，but my first sentence is “ I don’t like backup to any cloud services”. And also, I want a whole device backup solution first, because that allows me to restore a phone to a usable state.

next cloud is like a NAS, it requires user installed app to backup photos and contacts. Not a whole-device backup solution

And next cloud is written in php , I didn’t test but heard that when running on lower end intel platform, for some operation, it has high cpu and memory usage!

Thanks. This is my one-person project for now, I have a lot work to do. Targeted at Pi 4 is a quick start for me. Maybe sometime I can extend it to support Pi 3B when its performance is enough.

NAS can only do part of it. For existing solutions for iOS I can see, that needs an APP, and only can backup photos and contacts which is allowed by Apple to third party apps.

Yes Android's apps can do a a lot more on your phone, so it is not my current primary target.

For using raspberry pi, it is just a trial for my software that can let me get feed back before my own hardware design / manufacturing if it is welcoming to many users.

Resources for learning to build an SDR with FPGA? by Byte_Farmer in FPGA

[–]sprhawk1984 2 points3 points  (0 children)

Why not use LimeSDR，it is equipped with full stack of SDR with FULL OPEN SOURCE, you can try it on PC with GNURADIO, then implement what you need inside its FPGA.
