A computing system can be optimized for high security, reliability and/or integrity. The computing system can include a multiple instruction stream, single data stream processor. The multiple instruction stream, single data stream processor can include a master instruction processing unit, fetch instruction processing units, a single bus interface/memory unit, and a single data processing unit. The computing system can also include a storage device or a memory. The processor can be utilized in numerous applications including avionics software applications.

High security, multi-level processor and method of operating a computing system

A method of performing data detection for a global positioning system (GPS) receiver is disclosed. The method includes receiving a first in-phase (I) reference signal during a first time interval and receiving a first quadrature (Q) reference signal during a first time interval. The method also includes receiving a second in-phase (I) reference signal during a second time interval and receiving a second quadrature (Q) reference signal during a second time interval. The method further includes computing a first sum of the first I reference signal and the second I reference signal, computing a second sum of the first Q reference signal and the second Q reference signal, computing the difference of the first I reference signal and the second I reference signal; and computing the difference of the first Q reference signal and the second Q reference signal.
