While climbing through approximately 10;000 feet; we were alerted to a VIA (Versatile Integrated Avionics) FAILURE. After checking the QRH; multiple alerts began appearing. I contacted Maintenance Control and Dispatch and relayed our situation. They suggested a return to the departure airport. The alerts continued; and I declared an emergency. We had no map displays; the DU's (Display Units) were flickering; the Captains' airspeed indicator was unreliable; the stall warning was going off; no autopilot or autothrottles; and we were in manual pressurization mode. The First Officer was the flying pilot and did an outstanding job while I tried to prioritize what we had and didn't have. We landed and after evaluating the condition of the aircraft; decided to taxi to the gate with CFR trucks following us.It appears the #1 VIA had a complete failure. The QRH was no help. The level 1 alert only states; 'Do Not Change EIS Source' and that the fuel quantity comparator will be inaccurate. I feel the QRH should give you a bit more info as to what to expect.
A B717 VIA (Versatile Integrated Avionics) #1 failed in flight with numerous failures including the Captain's airspeed; stall warning; autopilot and autothrottles. An emergency was declared while the flight returned to the departure airport.
