Abstract
A flight recorder system of an aircraft includes a resource controller module (RCM) communicatively coupled, via a switch fabric, to a set of flight recorder system modules (FRM). Each FRM comprises a respective control module, a respective local memory, and a respective set of input and output (I/O) ports communicatively coupled to the switch fabric. The RCM is configured to detect a respective FRM coupled to the switch fabric, and based on the detection, configure an operation of the FRM, and wherein the respective local memory of the FRM is readable by the RCM, and shareable with the other FRMs via the switch fabric.
Claims6
A method of operating a flight recorder system of an aircraft, the flight recorder system including a first flight recorder module (FRM) having a first local memory and a first set of memory-mapped I/O ports and a second FRM having a second local memory and a second set of memory-mapped I/O ports, comprising:
- communicatively coupling a resource control module (RCM) to a switch fabric;
- communicatively coupling the first FRM and second FRM to the switch fabric;
- detecting, by the RCM, the first FRM;
- reading, by the RCM, at least one of the first local memory and the first set of memory-mapped I/O ports of the first FRM;
- configuring, by the RCM, an operation of the first FRM;
- providing data to the first FRM;
- saving a first portion of the data to the local memory of the first FRM;
- configuring, by the RCM, the switch fabric to enable the control module of the second FRM to access the local memory of the first FRM;
- and
- retrieving, by the second FRM, a second portion of the data from the first local memory of the first FRM;
- wherein the first and second FRM respectively comprise one of a cockpit voice recorder (CVR), a flight data recorder (FDR), or a crash-survivable recorder (CSR).
