Abstract: A processor having a limited amount of local memory for storing code and/or data utilizes a program stored in external memory. The program stored in external memory is configured into blocks which can be loaded individually into the local memory for execution. Queuing the individual blocks of code allows the program to be executed by the processor and also facilitates loading of the subsequent code to the executed. A semaphore system can be utilized to indicate which blocks of local memory are available/unavailable. The system can support the interaction of multiple independent programs in external memory.

Abstract: System and method for automatic fault-testing of a logic block and the interfaces of macros with logic gates inside a chip, using an at-speed logic-BIST internal to the chip. Following an initialization of internal storage elements, a set of test signals are generated and processed by the logic block. The output of the logic block is accumulated into a signature and compared to a reference signature to detect faults. Testing can be performed on an ATE (Automatic Test Equipment) using a simple test vector, or can be performed by a field engineer on the actual board comprising the chip.

Abstract: In a liquid crystal display (LCD) panel based display, a method of dynamically selecting either frame rate conversion (FRC) or pixel voltage overdrive is disclosed. The method is carried out by performing the following operations. A video vertical refresh rate of an incoming video data stream is determined and based upon the determining, only one video data stream conditioning protocol from a number of available video data stream conditioning protocols is selected.

Abstract: The invention relates to determining the image content of an incoming bitstream such that various image improvement effects may be accomplished. The invention provides for determining a realness value of an image formed of a plurality of pixels each having associated pixel data by evaluating a spatial distribution of luminance values of the image. Realness values are first determined for subregions of an image frame through an analysis of a luminance histogram generated for each subregion. Subsequently, the subregion realness values are analyzed to generate a total realness value for the image frame and to classify the image content of the image frame.
