i have been designing a pci target using spartan3 for some time. i m a new comer to this field and i have got some queries regarding the fpga configuration and its voltage requirements -
the motherboard that i m going to use, has 5V connector for sure. so i suppose the i/o s are 5V. now the spartan3 specifies its VCCO as 3.3Vmax. can this configuration of 5V pci and 3V spartan3, work reliably? are there any added precautions to be observed?
in the pci pinout, jtag pins are seperately specified. can i use these pins for configuration of the fpga? if so, can somebody suggest me a method/algorigthm/source code/software/link for this? has somebody used this before? in general, how can one address the jtag pins of pci target in windows or linux?
what throughput can i expect from the data acquisition system that i m going to put on the pci target card? i will be simultaneously using a modem, sound card, ethernet card.
will the operating system that i m going to use (windows or linux) have any bearing on the throughput? if yes, then if i program the card with its own operating system that is configured to work only with the acquisition card(i.e. if other pci cards are virtually rendered dead temperorily), will it improve the results?
