Xputer
The data stream-based Xputer machine paradigm is the counterpart to the command stream-driven Von Neumann machine paradigm . A Von Neumann computer has an instruction counter . However, an Xputer has one or more data counters instead. The Xputer paradigm, sometimes called "anti-machine", was derived from a generalization of the systolic array and its definition of the term "data stream": the "supersystolic array" (sometimes also "Kress / Kung machine") called). The duality of (Von-Neumann-) “computer” and (not-von-Neumann-) Xputer explains the paradigm shift from classic “computing” to reconfigurable computing . The first Xputer architectures were developed and implemented by the Xputer Lab at the University of Kaiserslautern in the 1980s , with speed-up factors of up to 15,000 being achieved by migrating from software to configware (computer-to-Xputer migration) for some applications. Since FPGAs were very small at the time, an electronically programmable PLA called DPLA was used for Xputer architectures. The DPLA was developed in Kaiserslautern as an integrated circuit and manufactured as part of the EIS project .
The term "Xputer" (a non-Von-Neumann computer) should not be confused with the " transputer " (which is a Von-Neumann computer).
