Static CMOS gate vs. LUT Number of transistors: Delay: Power:
NAND/NOR gate has 2n transistors. 4-input LUT has 128 transistors in SRAM, 96 in multiplexer (for LUT decoders, …). Delay: 4-input NAND gate has 9t delay. SRAM decoding has 21t delay. Power: Power consumption of static gates power depends on their activity. SRAM always burns power. مرتضي صاحب الزماني
