A state machine gesture recognition algorithm for interpreting streams of coordinates received from a touch sensor. The gesture recognition code can be written in a high level language such as C and then compiled and embedded in a microcontroller chip, or CPU chip as desired. The gesture recognition code can be loaded into the same chip that interprets the touch signals from the touch sensor and generates the time series data, e.g. a microcontroller, or other programmable logic device such as a field programmable gate array.

A verification module evaluates intermediate language code to verify that the code is type safe before passing the code for execution. Code that is not deemed type safe can cause execution errors, corrupt the runtime environment in which the code is executing, or cause unauthorized access to protected system resources. As such, the verification module protects a computer system from intentional or inadvertent breaches of the computer system's defenses. The verification module verifies the type safety of intermediate language code that supports significant high-level language constructs prohibited by verification modules in the prior art. One exemplary verification module verifies intermediate language code that includes one or more reference-based parameter, such as a pointer (or reference), a value class containing pointers, a RefAny parameter, or a nested pointer.

A system and methods for parallel processing of queries to one or more databases are described herein. One or more databases may be distributed among a subset of slave nodes of a global-results processing matrix. A query to the database may be generated using a query-based high-level programming language. The query-based source code then may be converted to intermediary source code in a common programming language and then compiled into a dynamic link library (DLL) or other type of executable. The DLL is then distributed among the slave nodes of the processing matrix, whereupon the slave nodes execute related portions of the DLL substantially in parallel to generate initial query results. The initial query results may then be provided to master node of the global-results processing matrix for additional processing, whereby the master node is adapted to execute one or more associated portions of the DLL on the initial query results.

A system and method describing a compatibility server for rehosting database applications written for a specific vendor's database on the database of a second vendor, without the need of rewriting the application to take into account differences in the application programming interfaces between the first vendor's database and the second vendor's database. Requests for access to the database are translated from one format to another at execution time. The server is also capable of translating error messages, data types and data formatting from the format used by the second database to that expected when making requests to the first database. Stored procedures defined in the first database are migrated to the second database as text blocks, and are translated at execution time into a high level programming language, compiled and executed against the second database. All information necessary for the mapping of schema, data, data types, error and status messages and data formatting, as well as information necessary to execute stored procedures, is stored in a plurality of metadata tables in the second database, which are created during a migration phase prior to executing the application.

Usage semantics allow for shaders to be authored independently of the actual vertex data and accordingly enables their reuse. Usage semantics define a feature that binds data between distinct components to allow them to work together. In various embodiments, the components include high level language variables that are bound by an application or by vertex data streams, high level language fragments to enable several fragments to be developed separately and compiled at a later time together to form a single shader, assembly language variables that get bound to vertex data streams, and parameters between vertex and pixel shaders. This allows developers to be able to program the shaders in the assembly and high level language with variables that refer to names rather than registers. By allowing this decoupling of registers from the language, developers can work on the language separately from the vertex data and modify and enhance high level language shaders without having to manually manipulate the registers. This also allows the same shaders to work on different sets of mesh data, allowing the shaders to be reused. Generally, semantics can be used as a data binding protocol between distinct areas of the programmable pipeline to allow for a more flexible workflow.

One or more machine code entities such as functions are created which represent solutions to a problem and are directly executable by a computer. The programs are created and altered by a program in a higher level language such as "C" which is not directly executable, but requires translation into executable machine code through compilation, interpretation, translation, etc. The entities are initially created as an integer array that can be altered by the program as data, and are executed by the program by recasting a pointer to the array as a function type. The entities are evaluated by executing them with training data as inputs, and calculating fitnesses based on a predetermined criterion. The entities are then altered based on their fitnesses using a machine learning algorithm by recasting the pointer to the array as a data (e.g. integer) type. This process is iteratively repeated until an end criterion is reached. The entities evolve in such a manner as to improve their fitness, and one entity is ultimately produced which represents an optimal solution to the problem. Each entity includes a plurality of directly executable machine code instructions, a header, a footer, and a return instruction. The instructions include branch instructions which enable subroutines, leaf functions, external function calls, recursion, and loops. The system can be implemented on an integrated circuit chip, with the entities stored in high speed memory in a central processing unit.

For example, the framework may issue statements to define the structure of a database, access information from the database, and/or manipulate information within the database.

A network processor has numerous novel features including a multi-threaded processor array, a multi-pass processing model, and Global Packet Memory (GPM) with hardware managed packet storage. These unique features allow the network processor to perform high-touch packet processing at high data rates. The packet processor can also be coded using a stack-based high-level programming language, such as C or C++. This allows quicker and higher quality porting of software features into the network processor. Processor performance also does not severely drop off when additional processing features are added. For example, packets can be more intelligently processed by assigning processing elements to different bounded duration arrival processing tasks and variable duration main processing tasks. A recirculation path moves packets between the different arrival and main processing tasks. Other novel hardware features include a hardware architecture that efficiently intermixes co-processor operations with multi-threaded processing operations and improved cache affinity.

The present invention is directed to a method and system for translating a high-level language (HLL) code such as C, C++, Fortran, Java or the like into a HDL code such as Verilog or VHDL which requires no modification in the original HLL source code, while supporting a cross call between software and hardware, and even recursive calls in hardware. The system includes: a HLL-to-HLL source translator which reads user programming directive from a translation-targeted high-level language code marked with the user directive, and separates the translation-targeted high-level language code into a hardware code part and a software code part; a main compiler which compiles the software code part; a HLL-to-HDL translator which includes the front-end and middle-end of the main compiler and a HDL backend; a main core which executes the compiled software code part; and a dedicated hardware which executes the HDL code.

A method of porting a video game or other application from one platform to another involves decompiling the game executable to develop source code in a high level programming language such as C. The (re)generated source code is re-linked using target native libraries to handle hardware functions (e.g., video, audio, etc.) for the target platform. The resulting “trans-compiled” executable is able to efficiently run on the target platform, potentially providing orders of magnitude speed performance boost over other traditional techniques.

A system and a method are disclosed for communicating between two programming languages on a client device. Commands in a high-level language are encoded as character string containing a series of numbers separated by delimiters, with each component of the command encoded as a different number. The encoded character strings are passed to compiled code that runs natively on the client device, and the native code decodes the character strings into corresponding native commands and executes the native commands. This communication protocol allows applications written in high-level code to perform functions that are typically set aside for native code, such as communicating with web servers and modifying files saved in memory. High-level code may also be transferred to client devices without being subjected to the restrictions that some operating systems place on the transfer for application binaries, which allows application developers to automatically send application updates to users.
