1. An electronic apparatus comprising: a processor; and a memory subsystem that includes B parallel memory banks accessible by the processor, B being an integer, wherein the B memory banks are to store B replicas of a look-up table of N elements, each memory bank storing N/B look-up table values, N being an integer divisible by B, wherein the processor is to access the B memory banks to obtain the N elements of the look-up table in N/B number of clock cycles, wherein when N equals 8, a number of clock cycles to be performed by the processor to access the B memory banks equals N/8.
