FLEX 8000 Programmable Logic Device Family Data Sheet

Logic Array Block

A logic array block (LAB) consists of eight LEs, their associated carry and

cascade chains, LAB control signals, and the LAB local interconnect. The

LAB provides the coarse-grained structure of the FLEX 8000 architecture.

This structure enables FLEX 8000 devices to provide efficient routing,

high device utilization, and high performance. Figure 2 shows a block

diagram of the FLEX 8000 LAB.
