Narrative:

Today operating flight [to] abq descending through FL230 multiple EICAS messages presented and we lost both pilot mfds (multi-functional displays); and the captain side FMS; along with multiple other systems including the autopilot; trim; and auto throttle. We leveled off and [advised ATC] and then ran the root QRH checklists: AC bus 1 off; dc bus 1 off; avionics mau 1B fail. We briefed the flight attendants and the passengers and we asked ATC to call the company. We continued to abq as we were on arrival and we landed without incident. The crash fire rescue monitored our brake temperature until the tug arrived and they accompanied us to the gate where we parked and deplaned without incident.
