Description

The CMOS ATT3000 Series Field-Programmable Gate Array (FPGA) family provides a group of highdensity, digital integrated circuits. Their regular, extendable, flexible, user-programmable array architecture is composed of a configuration program store plus three types of configurable elements: a perimeter of I/O blocks, a core array of logic blocks, and resources for interconnection. The general structure of an FPGA is shown in Figure 1.
