Xputer

The Xputer is a design for a reconfigurable computer, proposed by computer scientist Reiner Hartenstein. Hartenstein uses various terms to describe the various innovations in the design, including config-ware, flow-ware, morph-ware, and "anti-machine".

The Xputer represents a move away from the traditional Von Neumann computer architecture, to a coarse-grained "soft Arithmetic logic unit (ALU)" architecture.^[1] Parallelism is achieved by configurable elements known as reconfigurable datapath arrays (rDPA), organized in a two-dimensional array of ALU's similar to the KressArray.^[1][2][3]

The Xputer architecture is data-stream-based, and is the counterpart of the instruction-based von Neumann computer architecture.

The Xputer architecture was one of the first coarse-grained reconfigurable architectures,^[2] and consists of a reconfigurable datapath array (rDPA) organized as a two-dimensional array of ALUs (rDPU).
