Reconfigurable datapath array
From Wikipedia, the free encyclopedia
A reconfigurable datapath array (rDPA) is a coarse-grained morphware unit. Instead of field-programmable gate arrays having single bit configurable logic blocks (CLBs), rDPAs have multiple bits wide (for instance, 32 bit path width) reconfigurable datapath units (rDPUs).
rDPAs are structurally programmed from configware sources, compiled into pipe networks to be mapped onto the rDPA. rDPAs are not instruction-stream-driven and have no instruction fetch at run time. rDPUs do not have a program counter. The term reconfigurable datapath array or rDPA has been coined by Rainer Kress in 1993 when having been at TU Kaiserslautern.
