Over the past 25 years, programmable logic devices have grown in capacity and capability through lithography advancements and the integration of specialized functional blocks. First were dedicated memory arrays derived from the same SRAM used to build logic cells. Next came dedicated-function logic blocks such as multiply-accumulate units (MACs), to accelerate digital signal processing and other math-intensive algorithms, along with the integration of high-performance transceivers to speed the flow of data onto and off the FPGAs. And more recently, MACs and their ilk have been supplemented by even higher-complexity logic blocks, such as the dual-core Cortex-A9 ARM CPU subsystem in Xilinx's Zynq-7000 Extensible Processing Platform devices.
