应用背景The MAX 7000A device architecture is based on the linking of high-performance LABs. LABs consist of 16-macrocell arrays, as shown in Figure 1. Multiple LABs are linked together via the PIA, a global bus that is fed by all dedicated input pins, I/O pins, and macrocells.关键技术MAX 7000A macrocells can be individually configured for either sequential or combinatorial logic operation. The macrocells consist of three functional blocks: the logic array, the product-term select matrix, and the programmable register. Figure 2 shows a MAX 7000A macrocell.
