Abstract: A processor having a pipelining structure, in particular with a superscalar architecture, includes a configurable logic unit, an instruction memory, a decoder unit, an interface device, a programmable structure buffer, an integer/address instruction buffer and a multiplex-controlled s-paradigm unit linking contents of an integer register file to a functional unit with programmable structures and having a large number of data links connected by multiplexers. The s-paradigm unit has a programmable hardware structure for dynamic reconfiguration/programming while the program is running.
