| 14:17.33 | key2 | hey |
| 14:17.42 | key2 | what's the virtex that has 4 PPC inside ? |
| 14:40.15 | AchiestDragon | an expencive one in a 1700 pad or close bga package |
| 14:44.14 | AchiestDragon | according to the early data was suposed to be the 2vp250 but thay never releaced that the 2vp100 is the bigest and that has 2 ppc cpus |
| 14:48.17 | AchiestDragon | http://www.xilinx.com/products/silicon_solutions/fpgas/virtex/virtex_ii_pro_fpgas/product_table.htm |
| 15:45.43 | key2 | AchiestDragon: and it's possible to run a SMP linux ? |
| 15:45.44 | AchiestDragon | yes |
| 15:45.44 | vmaster | huh? |
| 15:57.33 | vmaster | are you sure about smp? iirc there's no cache coherency between the ppc cores |
| 15:58.11 | AchiestDragon | depends on how you confugure the fpga to work with it |
| 15:58.11 | AchiestDragon | well maybe not smb but multiproccessing is posible |
| 15:58.11 | AchiestDragon | smp rather |

| 16:53.15 | *** topic/#openjtag is This is the place to discuss development of Open JTAG tools and Bootloaders - http://www.openjtag.net/ |
| 16:54.48 | AchiestDragon | you could use a faster ppc micro and a fpga in seperate chips and get better performance form it at a farction of the cost |
| 16:58.40 | AchiestDragon | think there commetial use is limited to high performance ethernet routers as having up to 20 1Gbs ethernet ports on the same chip makes them good for that |
| 17:02.11 | AchiestDragon | nice chips though , if there price was in the $100 to $200 mark thay would be a good device and would find there way into lots of products |
| 17:03.33 | AchiestDragon | think thay will suffer the same fate as the transputer , the transputer was to be targeted with a £50 each tag , but dew to a buyout ended up with a £800 so it never got a good market share |
| 17:05.34 | AchiestDragon | that never got anyware as £800 for the chip priced any product that used it at more than 8 times the cost of one that would give the same performance |
| 17:05.49 | AchiestDragon | shame |
| 17:06.04 | key2 | AchiestDragon: http://www.broadcom.com/collateral/pb/1455-PB02-R.pdf |
| 17:06.07 | key2 | have a look there |
| 17:07.27 | key2 | AchiestDragon: it says it has the network integrated, so basically, if I put a MAC addr in 2 or 3 chips like that, and link them together by a swithching chip, do you think I could do a cluster of linux on the same board ? |
| 17:07.49 | AchiestDragon | should be able to |
| 17:08.10 | AchiestDragon | linux supports clusters over etherent |
| 17:08.24 | key2 | ? |
| 17:08.51 | key2 | like for its thread or forks ? |
| 17:09.00 | key2 | it can make an other computer handle it ? |
| 17:09.06 | vmaster | it has support for numa |
| 17:09.14 | AchiestDragon | i have seen cluster software for linux that allows some tasks to be distributed over the ethernet |
| 17:09.36 | key2 | wll the goal was to make a PBX with asterisk |
| 17:10.07 | key2 | should I put one linux on each quadproc and a loadbalancing in the swithching chip ? |
| 17:10.20 | key2 | or one asterisk and clustering with all the other quadproc with a linux on it |
| 17:10.49 | AchiestDragon | is it beowolf , cannot remeber but i do remeber on that allowed that with povray |
| 17:11.22 | key2 | AchiestDragon: the advantage of linking the chips together via Ethernet is the layout that is very simple |
| 17:11.27 | key2 | just use the RXs and TXs |
| 17:11.39 | AchiestDragon | yes |
| 17:11.41 | key2 | instead of 64bit PCI |
| 17:11.57 | key2 | btw, what would u recommend for designing the layout ? Orcad or Mantor graphic ? |
| 17:12.11 | AchiestDragon | protel dxp |
| 17:12.31 | key2 | AchiestDragon: better than Mantor ? |
| 17:12.59 | AchiestDragon | its what use , and i dont like orcad |
| 17:15.05 | AchiestDragon | http://www.whipy.demon.co.uk/geep.pdf |
| 17:15.05 | AchiestDragon | http://www.whipy.demon.co.uk/geep-sch.pdf |
| 17:15.15 | AchiestDragon | current project so far |
| 17:15.50 | key2 | AchiestDragon: what does it do |
| 17:17.17 | AchiestDragon | 200mhz arm , ehternet , rs232 , 2*usb , ac97 audio , 256mb ram , 512mb rom , ide,compact flash and dvi, with a fpga that provides a 100mhz expantion bus |
| 17:17.36 | AchiestDragon | 512mb flash rather not rom |
| 17:17.40 | key2 | what is it for ? |
| 17:18.20 | AchiestDragon | its a controler , genaral purpous , but going to be using it with a expantion bord for the open jtag project |
| 17:19.07 | key2 | it's gonna be expensive |
| 17:19.10 | AchiestDragon | that will provide jtag upto 150mhz , a 32chan logic analizer or a 150mhz sample rate DSO dependant on the adoptors used |
| 17:19.17 | key2 | why would u have ac97 for jtag :) |
| 17:20.00 | key2 | and protel DXP, is it expensive ? :) |
| 17:20.03 | AchiestDragon | the idea to kit out the board with most of the i/o was to make it usable for other projects |
| 17:21.00 | AchiestDragon | protel dxp is worth it as the cost of getting a 16 layer pcb wrong would workout at about the same cost |
| 17:22.13 | AchiestDragon | orcad is a pita to use and have had bad reports about some of its features reliability |
| 17:22.38 | key2 | and MG? |
| 17:22.47 | AchiestDragon | not used mg |
| 17:23.52 | AchiestDragon | protel dxp will do fpga simulation also |
| 17:24.02 | key2 | MG too :) |
| 17:24.05 | key2 | orcad too :) |
| 17:24.18 | AchiestDragon | will have to have a look at MG |
| 17:24.32 | key2 | xilinx uses MG for it's fpga sim |
| 17:24.36 | AchiestDragon | but already have dxp and it does what i want from it |
| 17:25.09 | key2 | what about the autorouter ? |
| 17:25.27 | key2 | works well ? |
| 17:25.52 | AchiestDragon | i hate autorouters , i perfer manualy routing but the dxp router is one of the better ones i have seen |
| 17:28.45 | AchiestDragon | and manualy routing from the netlist in dxp is easy and a plesure to use |
| 17:30.19 | key2 | AchiestDragon: and for example, if I have a bus in my schematic, can I make DXP make the wires the same size ? |
| 17:30.40 | key2 | for buses with high bw |
| 17:30.41 | AchiestDragon | yes and set it for equal track lenths |
| 17:30.47 | key2 | ok |
| 17:30.54 | key2 | I guess I have to emule around then :) |
| 17:31.10 | key2 | what about the library ? good or has to be redone ? |
| 17:32.35 | AchiestDragon | the libs are quite extensive and adding parts is easy enough , you set the bus track groups up in the schematic and pcb editor so there not dependent on the libs |
| 17:33.15 | key2 | what version do you use ? |
| 17:33.18 | key2 | 2004 or 2005 |
| 17:33.24 | AchiestDragon | 2005 |
| 17:34.23 | key2 | fuck |
| 17:34.26 | key2 | not easy to find :) |
| 17:34.40 | AchiestDragon | a company i know went bust and i managed to get there copy off them so it did not realy cost me anything , other than what thay owed me but still less than the asking price |
| 17:37.16 | key2 | any big difference between v2004 and 2005 |
| 17:37.18 | key2 | ? |
| 17:37.35 | AchiestDragon | ? i just have 2005 |
