Information about redundant computation is extracted by analyzing the interactions among the three basic blocks. Using this information, certain input operands of the [[arithmetic]] block and [[evaluation]] block can be frozen through input gating under specific run time conditions to reduce the unnecessary switching in the design. At the architecture level, if each trigger evaluation & data operation is regarded as an atomic action, then the EFSM implies an almost lowest-power implementation.

	~~# In E-block, evaluate all trigger conditions.~~

Hi there, I am Andrew Berryhill. He is an information officer. My husband doesn't like it the way I do but what I truly like performing is caving but I don't have the time lately.
