Abstract:
1. A computer-readable storage medium having a software embodied therein for execution by a computer, the computer-readable storage medium comprising: the software operable to configure a programmable logic device having a logic array block (LAB) having a logic element, the logic element including a first look up table and a second look up table, wherein the software is operable to selectively configure the first look up table and the second look up table of the logic element to implement a register function, wherein the software is implemented within a machine that implements the programmable logic device, wherein the software is further operable to selectively configure dedicated hardware associated with the logic element to configure the first look up table and the second look up table of the logic element to implement the register function, wherein the dedicated hardware includes a dedicated interconnect providing a clock signal as an input to the first look up table and the second look up table respectively, wherein the dedicated interconnect is connected to a LAB wide interconnect of the LAB.
