Has anyone seen the new Altera C5S (from terasIC) I can't see it on the Altera web site, but here's the link on terasic: http://www.terasic.com.tw/cgi-bin/page/ ... ish&No=816

for $249 it seems to have a lot of good features:
Cyclone V SOC 110k LEs
Dual core ARM Cortex A9 (on chip)
1GB RAM for FPGA
1GB RAM for ARM
24bit VGA (amiga AGA !)
micro SD (on bottom of board)
1Gb Ethernet

NO PS2 connector but USB 2.0 OTG (which I assume means you could connect a USB keyboard etc).
LCD display
audio in / out

and lots of other bits you can see from the link.

This looks really good to me, or am I missing something ?

I hadn't seen it but now I'm drooling! ;)

I got an advertising email about this board as DE2-115 user. Seems to be a good toy :) 2GB RAM, Cyclone 5, ARM....
... but there are some problems when using it as a retrocomputing base.

No GPIO, HSMC only :(
No PS2 (and with no GPIO this can be a problem)

Yes you're right no PS2 - I was hoping that a mouse and keyboard could be connected via a usb hub to the USB OTG interface. As far as GPIO - it does mention a 14 pin LTC connector for GPIO, but you may need an interface card from 'Linear Technology'.

This looks like it could be an interesting Minimig platform: http://www.terasic.com.tw/cgi-bin/page/ ... 0&PartNo=1

HDMI out, a hobbyist-friendly GPIO header, nice roomy FPGA and lots of DDR RAM.

Hi MMrobinsonb5, et al.

That C5G board at $179.00 looks like pretty good value.
I pre-ordered one, expected about mid-late December according to TerASIC.

If HDMI out is too much of a hassle, a DIGIASIC ADV7125/ADV7123 VGA board ($42.00) :
http://www.wayengineer.com/index.php?ma ... cts_id=160
can plug into the GPIO connector to give you a 24bit colour VGA output option.

These will also work with the DE0/DE1/DE0-nano series boards to give you improved VGA out.
Basically the same circuit as is already on the high-end DE2/DE2-115 boards.

Wiring up PS/2 connectors for a mouse/keyboard would be trivial.
The VGA board above leaves enough spare signals to wire it through that.

Cheers,
Red

And another one (and it's a DE1! :)) :
http://de1-soc.terasic.com

This one is sort of in the middle of the C5G and the C5S boards, it has the SoC FPGA on it (2xARM Cortex-A9), double RAM, ethernet, USB host, PS/2 and two 40-pin expansion headers like on the original DE1. Pretty nice in my opinion, but the price isn't published yet.

They sure are producing a boatload of boards all of a sudden! :)

Oh, nice! If the price isn't too eye-watering I'll definitely be investing in one of these!

Yup, exciting times! Strange, though, isn't it? For the last few years finding a board that has both a decent selection of ports and a good sized FPGA but doesn't cost the earth has been really difficult - and suddenly three such options appear almost simultaneously!

This is only name left.. maybe size, the rest is.... Cyclone V, 4x more LE's, ARM, IR, FTDI, ADC, accelerometer, VGA DAC. No place left for green leds, 6 hex instead.

This is the best board of all these Terasic's news, small, not overloaded, audio dac is at the FPGA side, VGA too, ftdi enables easy communication via usb, 2xARM with 1 GB DDR3... this is capable to simply run software retrocomputer emulator, and having possiility to directly control sound and video we can have 50 Hz display and sound without lags.

Likewise :) Since Arrow scre*ed me over the $99 SocKIT board (and I could barely get the money I paid for the SocKIT back form them, the cheating bastards!), I'm definitely looking for a new board, and this one is probably it.

Yes, it is surprising, looks like with the move to 28nm wafers (not expected to be so cheap!) it became lots cheaper to produce bigger FPGAs. Or maybe it's just competition doing its thing ;)

There are a few things to keep in mind with these SoC FPGAs though:
- while the embedded ARM CPUs are great, these are very complex beasts, and I doubt there is an easy way to do any bare-bones programming, so linux is a must.
- the AXI bus that connects the HPS and the FPGA parts is quite complex, with quite some latency and burst-oriented, so not a good match for low-latency short accesses
- it follows that accessing anything connected on the HPS side (in this case at least the SD card, USB OTG, UART) won't be so easy, especially using the SD card would be problematic for the minimig core - firstly, it is used to boot the HPS, and secondly, no direct access seems to be possible, and the manual for just the SD/MMC controller is 80 pages long :S

But on the other hand, running most of the minimig on the FPGA side and a CPU emulator on the ARM with local access to lots of fast memory might work great. I already did some experiments running a 68k simulator on a OR1200 core, and I don't think this is such a bad idea.

I guess all that would be needed is a small board with 2x joystick ports, 2xPS/2 ports and a microSD socket that could be used on any Terasic board with 2x20 GPIO connector. Maybe a few spare pins for SPI addons, like USB or ethernet.

Of course, a board like this one is usable for a lot of projects besides minimig :)
