摘要： A system and method for generating a variably scaled digital image. A second digital image containing a second plurality of pels is generated from first digital image containing a first plurality of pels. The first digital image may be stored in an image buffer. Each of the first plurality of pels is input serially into a process whereby a first and a second scaling factor are applied to the luminance values associated with a pel. A determination is made as to whether or not the scaled luminance values overflow vertically and horizontally into surrounding pels in the second plurality of pels. If the scaled luminance values overflow vertically, the overflow is stored in a line buffer to be added to future scaled luminance values. If the scaled luminance values overflow horizontally, the overflow is accumulated in an accumulator to be added to future scaled luminance values. Once a pel in the second plurality of pels is completely filled with luminance values, the pel is output to a buffer and is ready to be displayed.

摘要： Techniques for use in accordance with application performance decomposition are provided which take advantage of the communications protocol used to carry a transaction between application components in a distributed computing network. Specifically, the invention extends the communications protocol by embedding data, such as timestamp and duration measurement data, in the protocol itself, rather than extending or altering the application or transaction data carried by the protocol as in existing approaches. Thus, the invention provides natural correlation of interactions of distributed application components on such transactions without modification to the application or transaction data. Because the correlation is performed in-line with the application component interactions, minimal data management overhead is required, and correlated performance decomposition is made possible in real-time for the transaction. Furthermore, subsequent processing stages of the distributed application can interpret the communications protocol to glean processing durations of previous stages in order to make decisions regarding treatment of the transaction.
