5-8-8 Front End Interface Board (GFI)
5-8-8-1 General description
The GFI is the Front End Processor’s (FEP’s) interface to the Back End Processor (BEP).
During boot, various setup parameters are downloaded from the BEP’s hard drive, via the PCI Express
bus to the GFI2 board.When a scanning mode is selected, or scanning parameters are adjusted, the
GFI board receives setup parameters from the BEP and pass these on to the FE boards. The GFI also,
based on some of these parameters, control some front end signals directly.
The digitized and beamformed ultrasound data, received from the DRX boards, are further processed
on the GFI board before the result is sent to the BEP for use in the display system.
