Abstract

A reconfigurable device includes a plurality of function cells and a programmable interconnect network which programmably connects the function cells. The programmable interconnect network includes horizontal programmable interconnect ways and vertical programmable interconnect ways. Each horizontal programmable interconnect way includes a short horizontal programmable interconnect channel and a long horizontal programmable interconnect channel, and each vertical programmable interconnect way includes a short vertical programmable interconnect channel and a long vertical programmable interconnect channel. In the horizontal programmable interconnect way, both the short horizontal programmable interconnect channel and the long horizontal programmable interconnect channel are constructed to have 'shift structure', thereby 'sector segmentation' and problems related to the sector segmentation are avoided. The function cells are directly connected to the short horizontal programmable interconnect channel, but are not directly connected to the long horizontal programmable interconnect channel, therefore, signal transfer of input/output signals between the function cell and the long horizontal programmable interconnect channel is conducted necessarily through the short horizontal programmable interconnect channel and a programmable switch, thereby load capacitance on the long horizontal programmable interconnect channel is reduced and thereby high-speed signal transfer is realized.
