Abstract

Disclosed herein is a monitoring method and apparatus for an ARINC 653-based operating system. In the monitoring method for an ARINC 653-based operating system according to the present invention, a client system transfers information about a breakpoint to a target system. The breakpoint information is set in the target system. A Micro Controller Unit (MCU) reads a Program Counter (PC). If the breakpoint information matches the PC, an interrupt is caused. A function contained in the breakpoint information matching the PC is executed.

Claims

1. A monitoring method for an Aeronautical Radio, Incorporated (ARINC) 653-based operating system, the method comprising:

transferring, by a client system, breakpoint information about a breakpoint to a target system;

setting the breakpoint information in the target system;

reading, by a micro controller unit, a program counter;

if an address value of the breakpoint contained in the breakpoint information matches a value of the program counter, causing an interrupt of operation of the target system; and

executing a monitoring function contained in the breakpoint information matching the value of the program counter.

2. The monitoring method of claim 1, wherein the breakpoint information includes an Instruction Address Breakpoint Register (IABR) setting information.

3. The monitoring method of claim 2, wherein setting the breakpoint information comprises:

transferring, by a monitoring agent unit, the breakpoint information to a monitoring management unit by invoking a system call; and

setting, by the monitoring management unit, the address value of the breakpoint at a location of an IABR determined depending on the IABR setting information.

4. The monitoring method of claim 1, wherein executing the monitoring function contained in the breakpoint information matching the value of the program counter is configured such that, as an interrupt occurs, an interrupt service routine unit checks an Instruction address Breakpoint Control Register (IBCR) to determine a location of an IABR in which an address value of the breakpoint is set, and such that a monitoring function included in the location of the determined IABR is executed.

5. The monitoring method of claim 1, further comprising, before transferring the breakpoint information, initializing breakpoint information in the target system.

6. The monitoring method of claim 5, wherein initializing is configured to, if the breakpoint information is included in an initialization routine of a kernel of an operating system or if the breakpoint information is included in an entire initialization routine of the target system, perform initialization.

7. A monitoring apparatus for an Aeronautical Radio, Incorporated (ARINC) 653-based operating system, the monitoring apparatus comprising:

a monitoring agent unit for transferring information about a breakpoint received from a client system to a monitoring management unit;

the monitoring management unit for setting the breakpoint information in a register, causing an interrupt of operation of a target system if an address value of the breakpoint contained in the breakpoint information matches a value of a program counter, and executing a monitoring function contained in the breakpoint information matching the value of the program counter; and

an interrupt service routine unit for defining a processing routine to be executed when the breakpoint information matches the value of the program counter.

8. The monitoring apparatus of claim 7, wherein the monitoring agent unit transfers the breakpoint information to the monitoring management unit in a form of a system call.

9. The monitoring apparatus of claim 7, wherein the breakpoint information includes an IABR setting information.

10. The monitoring apparatus of claim 9, wherein the monitoring management unit sets the address value of the breakpoint at a location of an IABR determined depending on the IABR setting information.

11. The monitoring apparatus of claim 7, wherein the monitoring management unit is configured such that, as the interrupt occurs, the interrupt service routine unit checks an IBCR to determine a location of an IABR in which an address value of the breakpoint is set, and such that a monitoring function included in the location of the determined IABR is executed.
