A method of producing a reconfigurable circuit device for running a computer program of moderate complexity such as multimedia processing. Code for the application is compiled into Control Flow Graphs representing distinct parts of the application to be run. From those Control Flow Graphs are extracted basic blocks. The basic blocks are converted to Data Flow Graphs by a compiler utility. From two or more Data Flow Graphs, a largest common subgraph is determined. The largest common subgraph is ASAP scheduled and substituted back into the Data Flow Graphs which also have been scheduled. The separate Data Flow Graphs containing the scheduled largest common subgraph are converted to data paths that are then combined to form code for operating the application. The largest common subgraph is effected in hardware that is shared among the parts of the application from which the Data Flow Graphs were developed. Scheduling of the overall code is effected for sequencing, providing fastest run times and the code is implemented in hardware by partitioning and placement of processing elements on a chip and design of the connective fabric for the design elements.

This invention relates generally to a system for processing database queries, and more particularly to a method for generating high level language or machine code to implement query execution plans. In one preferred embodiment, the method begins by receiving a subject query, and then forming an execution plan corresponding to the subject query. The execution plan will typically have a sequence of component snippets or pieces and corresponding processes for implementing the pieces. For at least one piece in the plan, the process then (a) generates source code using different code generation techniques as a function of expected runtime processing machine types; and then (b) compiles the generated source code to form machine executable code for implementing the subject query. As a result, the query executed directly as machine executable code thereby avoiding runtime interpretation of the pieces in the execution plan.

The read latency caused by job start preparation of a future job is at least partly hidden within the current job by reading information for job start preparation of the future job integrated with the execution of the current job. Instructions for job start preparation are preferably instrumented (701) into the current job and executed (702), whenever possible, in parallel with the instructions of the current job. The integrated job start preparation may include table look-ups, register file updating, instruction fetching and preparation. If the scheduled job order is allowed to change during execution, it is typically necessary to test (703) whether the next job is still valid before starting the execution, it is typically necessary to test (703) whether the next job is still valid before starting the execution of the next job and take appropriate actions (704; 705, 706) depending on the outcome of the test. In addition to reduced job start preparation time, unused slots in the instruction-parallel execution of the current job may be filled up by the added read instructions, thus providing more efficient utilization of the multiple functional execution units of the processor.

A compilation technique for computer programs forms a data flow graph of vertices which are analysed to form clusters C for parallel execution where those clusters are added to up to the point at which arbitrary selection between further vertices C, D to be added must be made. This data flow graph with these small clusters is then scheduled such that the clusters do not overlap with other clusters or with vertices outside of clusters. This starting point scheduled data flow graph is then subject to iterative processing whereby a window of timestamps is analysed to see if a candidate cluster formed by the parallel execution of the vertices within that window will result in faster execution whilst avoiding exceeding architectural constraints, such as register occupancy. If the rescheduled vertices do improve performance without exceeding architectural constraints, then this new schedule is adopted and the following vertices are subject to an adjustment in their timestamps to account for this. A window at a different point within the schedule is then adopted and an attempted rescheduling examined. This process is repeated until no progress is being made in reducing the overall execution time.

The invention is a system and method used for teaching and learning computer programming. This system incorporates visualization, plan abstraction and its integration, and language constructs into one teaching and learning environment known as VPCL. There are three phases of VPCL, Plan Observation or Rehearsal, Plan Integration or Composition, and Plan Creation or Innovation. The observation Phase teaches how a program (plan) is broken down into smaller components known as a plan with their relationship. Each plan may further break down into smaller plans. At the last level plans are illustrated by language constructs. The integration phase concentrates on how plans are related to each other to build a program using the four methods of integration. The creation phase concentrates on how a new plan is created using the existing plans along with system resources. VPCL can be applied to other problem solving tasks such as mathematics, science, physics, chemistry, biology, or linguistics.

The present invention is related to production schedules in a refinery and, more particularly, refinery production schedules by genetic programming in domain specific language. In this scenario, the present invention provides a method and an optimization system based on linear genetic programming oriented to grammar and with quantic inspiration using a domain specific language for the solution of oil programming problems, in addition to a readable medium comprising instructions to perform this said method.
