Hello all,
Can someone please answer the following questions?
- I am using a VGA graphics core with 60Hz refresh rate and 640x480 pixels (24bit), requiring about 25MHz xtal. The FPGA development board comes equipped with that, the problem is how to provide a fast pixel access. The SDRAM connected has an access time of 15ns, if I could just come up with some method to update the SRAM contents very quickly, i can display moving graphics onto the monitor using FPGA? Are there any simple graphic chips which can do this job for custom display designs without using the processors?
- The second question indirectly relates to the PCI, however, before that, can someone please tell me exactly how plug and play works? When the computer boots what steps are taken and how the system determine how many legal devices are connected to the pci.
- The base address register, it is not hardwired but assigned on the fly? I have problems understanding the configuration step in the pci core. Any comments for a starter?
Thanks in advance
Mak
