Programmable logic array integrated circuits with blocks of logic regions grouped into super-blocks |
摘要 |
A programmable logic array integrated circuit device has logic regions grouped in blocks, which are in turn grouped in super-blocks. The super-blocks are disposed on the device in a two-dimensional array of intersecting rows and columns. Global conductors are associated with each row and column. Super-block feeding conductors associated with each super-block feed signals from the global conductors to any logic region in the super-block. Local feedback conductors feed back logic region output signals to all logic regions in a block. The super-block feeding conductors are also used to interconnect the logic regions in a super-block so that the global conductors do not have to be used for that purpose.
