Narrative:

Prior to departure; maintenance reset a system 2 press fault. During cruise at FL380 we once again encountered and advised maintenance of a system 2 press fault. Approximately 5-10 minutes later we experienced a system 1 press fault; followed by an ECAM directed emergency descent. We followed the ECAM guidance and requested an immediate descent to 10;000 ft with center. Due to terrain; the controller could only clear us to 12;000 ft; which required both pilots to remain on oxygen while coordinating with each other; flight attendants; dispatch and turning on the seatbelt sign. With the weather being completely VFR and unlimited visibility; we requested a descent to 10;000 ft and would maintain our own terrain separation. ATC cleared us to descend and track off course if necessary. At this point communications became much easier after removing the oxygen mask; which had fogged up. The first officer flew the aircraft and talked to ATC; while I discussed the situation with the flight attendants; confirming the cabin oxygen masks did not deploy and no injuries to crew or customers. After briefing the passengers on what had transpired my focus then turned to coordinating a plan with dispatch and maintenance control. Based on terrain analysis and fuel planning; we were able to continue to our diversion airport. Everyone on board was told of our intent and the station was well prepared for our arrival. The first officer and I created an arrival strategy using all of our available resources; including the fom diversion guide. Maintenance control indicated he would log the items in the maintenance computer for us; knowing it was a busy time. We landed without further incident.

Title: An A320 flight crew received ECAM pressurization system pressure warnings for systems one and two. The ECAM directed an emergency descent so the crew declared an emergency and diverted for maintenance.
