Shortly after reaching cruise at FL340 we had an ADR1 fault ECAM. We ran the checklist. Within a minute; the autopilot disengaged; the autothrottles disengaged; all FMA's disappeared; and the FD's disappeared. We lost all autoflight capability. I hand flew the airplane while the F/O ran the ECAMs. We coordinated with ATC and dispatch to divert into KIAH. I performed an uneventful overweight landing at IAH.
At cruise altitude; A320 flight crew experienced ADR1 fault with the loss of FMA's and Autopilot. The flight crew diverted.
