Abstract: A system and method for managing data in a ring buffer is disclosed. The system includes a legacy ring buffer functioning as an on-chip ring buffer, a supplemental buffer for storing data in the ring buffer, a preload ring buffer that is on-chip and capable of receiving preload data from the supplemental buffer, a write controller that determines where to write data that is write requested by a write client of the ring buffer, and a read controller that controls a return of data to a read client pursuant to a read request to the ring buffer.

Abstract: A graphics processing apparatus, system, and method is provided. The graphics processing method includes separating a graphics context and graphics object from a packet; calculating a magic number of the graphics context; comparing the magic number of the graphics context with magic numbers stored in a context table, wherein each of the magic numbers corresponds to a specific graphics context; and, if the magic number of the graphics context is not found among the magic numbers in the context table, adding the graphics context to a graphics context slot of a graphics context storage, adding the graphics object to a graphics object list separate from the graphics context storage, and associating the graphics context slot with the listed graphics object.

Abstract: A method and apparatus for automated performance verification for integrated circuit design is described herein. The method includes test preparation and automated verification stages. The test preparation stage generates design feature-specific performance tests to meet expected performance goals under certain workloads using optimization approaches and for different design configurations. The automated verification stage is implemented by integrating functional, automated modules into a verification infrastructure. These modules include register transfer level (RTL) simulation, performance evaluation and performance publish modules. The RTL simulation module schedules performance testing jobs, runs a series of performance tests on simulation logic simultaneously and generates performance counters for each functional unit. The performance evaluation module consists of three sub-functions including a functional comparison between actual results and a reference file containing the expected results, performance measurements for throughput, execution time, and latency values, and performance analysis. The performance publish module publishes performance results and analysis reports.
