The farming of maize began in Mesoamerica in 6000 B.C.
The domestication of maize made the city of Tenochtitlan possible by providing the Aztecs the ability to feed millions. Unlike the corn that is known today, the early maize had tiny cobs but dramatically became bigger and more nutritious as time passed.
Answer:
2.82
Explanation:
The computation of the average number of cycles per instruction is shown below:
= Arithmetic/logical operations × frequency cycles + Register load operations × frequency cycles + Register store operations × frequency cycles + Unconditional branch instructions × frequency cycles + Conditional branch instructions × frequency cycles
= 45% × 1 + 18% × 5 + 10% × 2 + 7% × 1 + 20% × 6
= 0.45 + 0.9 + 0.2+ 0.07 + 1.2
= 2.82
