摘要： Techniques are described herein for using configurable logic constructs in a loop buffer. In an embodiment, a configurable hardware block is programmed based on one or more target functions within a loop. The configurable hardware block is associated with a plurality of registers, including a loopcount register and a first output register. For each iteration of the loop, a counter value in the loopcount register is updated and a target value in the first output register is updated using the programmed configurable hardware block. For each iteration of the loop, a set of one or more instructions may be fetched from the instruction buffer and executed based on the updated target value in the first output value.

摘要： Techniques for Aligned Run-Length Encoding (ARLE) are described. ARLE is an encoding scheme that transforms sets of same-valued consecutive rows into one or more runs, while enforcing boundaries between the runs at set intervals (e.g. every predetermined number of rows). Consecutive rows that contain the same value, but which cross one or more interval boundaries, are encoded as multiple runs that are divided along those interval boundaries. According to one technique, a database server accelerates query processing by setting the interval size to the word size of the processor performing the predicate comparisons. According to another technique, a database server accelerates row lookup by maintaining an offset array that stores the run offsets into the ARLE data of the run that begins each interval.

摘要翻译：描述了对齐运行长度编码（ARLE）的技术。 ARLE是将相同值的连续行的集合转换为一个或多个运行的编码方案，同时以设定的间隔（例如每个预定数量的行）强制运行之间的边界。包含相同值但跨越一个或多个间隔边界的连续行被编码为沿着这些间隔边界划分的多个运行。根据一种技术，数据库服务器通过将间隔大小设置为执行谓词比较的处理器的字长来加速查询处理。根据另一种技术，数据库服务器通过维护一个偏移数组来加速行查找，该偏移数组将运行偏移量存储到每个间隔开始的运行的ARLE数据中。
