Let the instructiоns оf а prоcessor with а clock rаte of 3.12 GHz be divided into four classes A, B, C, and D with CPIs 1, 1.5, 2.4, and 3.0 respectively. In a given program, the dynamic instruction count is 3.0E9, and instructions are divided into classes as follows: 16% class A, 24% class B, 40% class C, and 20% class D. The processor's global CPI is [blank1]. It takes [blank2] seconds for the processor to execute the given program.
