Dedicated connection paths on APEX^™ 20K, APEX^™ II, ARM^®-based Excalibur^™, FLEX^® 6000, and Mercury^™ devices that allow signals to travel quickly between logic cells in the same LAB or adjacent LABs; between logic cells adjacent to I/O pins; or from logic elements to Embedded System Blocks (ESBs). Shared local interconnect is the fastest interconnect available in these devices.
