The image below shows a 32-bit PCI card which includes two programmable DAC channels, 16 analog acquisition channels with programmable gain acquiring in phase at 1.2MSps, and 8 DSP post-processors. The result is sent over the PCI bus. The design included the consideration of many signal integrity issues. Many asynchronous state machines interface high level software to the card subsystems. The firmware design is in-system-reprogrammable, allowing for remote "hardware" updates via the internet.
