A thin client intelligent transportation system wherein geospatial roadmaps and map matching systems are maintained in roadside nodes and are more fully exploited. The thin client approach offers significant advantages over thick client approaches that rely on on-vehicle maps and map matching systems, including reduced complexity of on-board equipment and elimination of map integrity issues. The thin client approach also offers significant advantages over systems wherein the vehicle is required to access maps and map matching systems in real-time from a remote data center, including the ability to meet the low latency requirements for many vehicle safety applications. The present invention in some embodiments has added advantages in that it exploits roadside maps and map matching systems in revenue generating applications that are not directly related to passenger safety.

A computer has instruction pipeline circuitry capable of executing two instruction set architectures (ISA's). A binary translator translates at least a selected portion of a computer program from a lower-performance one of the ISA's to a higher-performance one of the ISA's. Hardware initiates a query when about to execute a program region coded in the lower-performance ISA, to determine whether a higher-performance translation exists. If so, the about-to-be-executed instruction is aborted, and control transfers to the higher-performance translation. After execution of the higher-performance translation, execution of the lower-performance region is reestablished at a point downstream from the aborted instruction, in a context logically equivalent to that which would have prevailed had the code of the lower-performance region been allowed to proceed.

A transmitter and receiver communicate using a modified superposition coding scheme. The transmitter transits superposition symbols which include a near end symbol for a near receiver and a far end symbol for a far receiver. The transmitter modifies the near end symbol depending on the far end symbol prior to transmission. Specifically, the near end symbol may be mirrored around the real or imaginary axis. The near receiver generates mirrored superposition symbols by applying mirroring to each received superposition symbol around at least one of the real axis and the imaginary axis in response to the value of the received symbol. The mirroring may remove the uncertainty of the far end symbol value allowing a simpler decision for the near end symbol. The mirroring performed by the transmitter and the near receiver will negate each other for the near end symbol thereby allowing a simplified near end receiver operation.
