摘要： Variants of the HIV-1 Tat protein exhibiting higher transcriptional activation and stronger P-TEFb binding than wild-type Tat are provided. In addition variants that can inhibit transcription activation by wild-type Tat are provided. Nucleic acid sequences encoding these variants, vectors and host cells for expression of these variants, and antibodies raised against these variants are also provided. In addition, methods for use of these variants and compositions containing these variants as research tools, as diagnostic tools and in the treatment of viral infections are provided.

摘要： A digital video presentation system is provided with hardware and software logic for mapping the picture data into buffer memory in a way that permits both the reading of motion vector compensated macroblocks of data and the reading of horizontal picture wide scan lines with a low number of memory page crossings. Preferably, the memory is a plurality of rows, for example 16 rows, wide. Preferably, 16 lines of 8-pixel (two 32 pixel wide column) line segments of 8.times.8 pixel blocks are stored in consecutive storage locations followed by the consecutive storage vertically adjacent line segments until one line segment is stored in each logical row of the memory. Then the next horizontally adjacent set of line segments of similarly stored until the right boundary of the picture is reached, then the each additional row of 16 lines of the picture similarly are stored until the bottom of the picture is reached. Each 16.times.16 pixel macroblock of data is stored on a single page; preferably, two horizontally adjacent macroblocks are stored on one page of memory. Each line of the picture is stored in contiguous locations on the same row of the memory. The motion compensation logic interprets motion vectors from the incoming data and calculates addresses for a macroblock of picture data by separating read commands into separate commands where a page boundary divides the macroblock into vertically adjacent rectangles. Memory controller logic further divides such rectangles where they cross boundaries between horizontally adjacent pages of the memory. One fixed address increment of 8 hex steps from line segment to vertically adjacent line segment while another fixed address increment of 80 hex steps horizontally from one 8 pixel line segment to the next, such as across a scan line of the picture.

摘要： A pipelined data processor has instructions at different stages of execution. Some of the instructions specify virtual addresses into a file of registers having physical addresses. A speculative translator maps the virtual registers of an instruction at one pipeline stage into physical registers for speculative use by the instruction at a later pipeline stage. The registers have multiple differently translated regions. Failure of speculative renaming reverts to an archive copy of renaming data.
