A method for real time programmability of an engine electronic control unit (ECU). The present invention allows a user to update calibration data previously stored in memory in the engine ECU with new calibration data sent from an external device. The user can monitor the effects of the new calibration data on the engine instantaneously without having to wait for a period of time for the new calibration data to be permanently stored in the engine ECU's memory. To permanently store the new calibration data into the main memory, an erase / reprogram subroutine is uploaded from the main memory to a temporary memory. After the erase / reprogram subroutine is uploaded into the temporary memory location, the erase / reprogram subroutine will execute and permanently download the new calibration data into the main memory in response to a predetermined vehicle event.

A graphics controller which performs display list-based video refresh operations and compresses assembled scan lines or portions thereof is disclosed. The graphics controller maintains a virtual display refresh list (VDRL) comprising a plurality of pointers to scan line segments in memory. The graphics controller may also create, maintain, and delete draw display lists (DDLs) that comprise pointers to object display list subroutines (ODLs) that independently draw objects in memory. The ODLs may allocated one or more buffers in memory into which different frames of the objects are drawn. When an ODL has completed executing, the corresponding pointer in the DDL may be updated to point to the buffer location in memory that stores the newly completed object frame. The VDRL is maintained independently (and may be doubled-buffered) and is updated using the DDLs. The video data assembled as the VDRL is executed is output to the display device. The video data may also be compressed and stored into memory. If the underlying graphics objects have not been changed since the previous screen refresh, the compressed video data in memory may be used in lieu of following the corresponding pointers in the VDRL.

A method is provided for tracking the type of at least one local variable after calling a subroutine. The exemplary method associates each one of a plurality of branch instructions calling the subroutine with a first information, which indicates the type of value stored in the local variable when each one of the plurality of branch instructions is executed. The exemplary method associates at least one execution point-of-interest within the subroutine with a second information. The execution point-of-interest is any point within the subroutine where it may be necessary to ascertain the type of each local variable. The second information is a data structure indicating a change in type made to the local variable after entering the subroutine and before the execution point-of-interest. The exemplary method associates the execution point-of-interest with a return address for the subroutine. This return address enables the method to identify the point in the calling program from which the current subroutine was called. When a request is received to identify the type of the local variable at the execution point-of-interest in the subroutine, the exemplary method obtains a second map from the second information using the execution point-of-interest. The second map indicates the change in type of the local variable made within the subroutine. The method also obtains the return address associated with the execution point-of-interest, and obtains a first map from the first information using the return address. The first map indicates the type of value stored in the local variable when one of the branch instructions is executed to call the subroutine. Given the first and second maps, the exemplary method merges the first map with the second map to identify a current type for the local variable. In performing this merge, the method combines the type status of the local variable as modified by the subroutine with the type status of the local variable as it stood before calling the subroutine.

The present invention encompasses a self-orthogonal character recognition engine for executing an iterative method employing a database of predetermined character strings. The method receives a digital representation of a character string. It then generates a proposed result string by applying to the captured digital image a predetermined recognition routine including one or more recognition subroutines. Each recognition subroutine employs an initial parameter setting. Next, if the proposed result string does not match any of the predetermined character strings in the database, the initial parameter setting of a recognition subroutine is changed to a next setting. The recognition process is then repeated using the next parameter setting to generate and test a next result string. The process can be repeated iteratively until a result string is verified or the process times out.

Such an architecture provides sufficient flexibility to disable certain validations when they are not applicable to the flow, interpret validation failures differently according to requirements of the calling application, and specify the type of document for which a particular validation is applicable. The architecture provides a standardized flow for performing data validation, specifying a set of required parameters for validation subroutines, as well as where validation results are to be stored for access by a calling program. Such an architecture also provides a framework for performing common processing required for most validation flows without restricting the flexibility of the validation subroutines.
