Abstract
Provided are a decoder unit, a decompressor unit, and method for a decoder of multiple stages of adders to decode delta encoded data. A decoder unit implemented in a cache memory having a cache memory cell array comprises a first stage of adder circuits to add, in parallel, pairs of encoded items transformed using a delta encoding, wherein the encoded items include a plurality of deltas of neighbors of sequential source items. The decoder unit further comprises at least one successive stage of adder circuits to add, in parallel in each stage, pairs of outputs from a previous stage of adder circuits, wherein each successive stage has fewer adder circuits than the previous stage, and wherein output from a last of the at least one successive stage comprises the sequential source items.
