I want to ask this question from Performance Management Tradeoffs in chapter Technology Tradeoffs in Software Defined Radio of Cognitive Radio

Answer 1

Right answer is (c) Thread activation rate* Complexity * Sub thread load factor

Explanation: The total software demand is given by the product of thread activation rate, complexity, and sub thread load factor. The load factor reflects the number of times a sub thread is invoked for an incoming stimulus. The number of instructions per invocation is called the complexity.
