Appl. No.:

13/162260

Inventors:

Gregory M. Wellbrook - Long Beach CA, US
Charlie Wang - Huntington Beach CA, US

International Classification:

H03M 1/12

G06F 17/00

US Classification:

701 3, 341155, 341110

Abstract:

A dynamically reconfigurable electrical interface is disclosed that can be used in various applications, including avionics communications. In one embodiment, a first switch receives an input signal and routes it to the applicable signal conditioning path unit that conditions the input signal, after which a second switch routes it to an amplifier. The amplifier provides an amplified signal to an analog-to-digital converter that generates a corresponding numerical value based on the voltage of the amplified signal that is analyzed by a processor to determine information conveyed by the input signal based on a particular electrical interface. Multiple distinct interfaces can be accommodated by on one more processors accessing instructions sets for processing information corresponding to a particular electrical interface. In another embodiment, the processor provides numerical values to a digital-to-analog converter producing an analog signal that is amplified, routed, and conditioned to convey information using a particular electrical interface.

Abstract:

A method for validating the data defining an executable program prior to loading of the data for program execution is described. The method includes calculating a verification number for the data within a primary data storage area, the data defining an executable program, comparing the calculated verification number with a stored number, executing the program within the primary data storage area if the verification number matches the stored number, calculating a verification number for the data within a secondary data storage area, the data within the secondary data storage area defining the same executable program as that within the primary data storage area, if the verification number and the stored number do not match, comparing the calculated verification number for the data within the secondary data storage area with the stored number, causing the program to be executed if the verification number for the data within the secondary data storage area and the stored number match, and indicating a failure if the verification number for the data within the secondary data storage area and stored number do not match.
