Vibration frequency response function can be calculated, thereby characterizing the system. This technique is used in the field of experimental modal analysis to determine the vibration characteristics of a structure. The simple mass–spring–damper model is the foundation of vibration analysis, but what about more complex systems? The mass–spring–damper model described above is called a single degree of freedom (SDOF) model since the mass is assumed to only move up and down. In more complex systems, the system must be discretized into more masses that move in more than one direction, adding degrees of freedom. The major concepts of multiple degrees of
Cycles per instruction the number of clock cycles it takes to execute an instruction is 1/2 (CPI = 1/2 < 1). For the multi-cycle MIPS, there are five types of instructions: If a program has: then, the CPI is: formula_6 A 400-MHz processor was used to execute a benchmark program with the following instruction mix and clock cycle count: Determine the effective CPI, MIPS (Millions of instructions per second)rate, and execution time for this program. formula_7 formula_8 since: formula_9 and formula_10 formula_11 Therefore: formula_12 Cycles per instruction In computer architecture, cycles per instruction (aka clock cycles per instruction, clocks per instruction, or CPI)
