Abstract :
A memory-based logic block (MLB), which is a building block for memory-based reconfigurable computing framework, is presented in 130-nm CMOS. The MLB is designed with an optimized-for-read (OFR) 6T static random access memory (SRAM)-based lookup table and demonstrates single- and multicycle evaluation of complex functions. Power-aware mapping leverages the data-dependent read power of the OFR SRAM to reduce MLB evaluation power.
