Abstract
Methods and apparatuses for run length encoding using a vector processing unit. In one aspect of the invention, a method for execution by a microprocessor in response to the microprocessor receiving a single instruction includes: receiving a first list of a plurality of elements from a first vector register; generating a plurality of run values respectively for the first list of elements, at least one of the plurality of run values indicating the number of consecutive elements of a first value immediately preceding the corresponding element in the first list; and outputting the plurality of run values into a second vector register; where the above operations are performed in response to the microprocessor receiving the single instruction.
