The theoretical method for evaluating and comparing the performance of ARM-based processors
The main purpose of this paper is to develop a theoretical method for estimating the performance of ARM-based processors. This method is based on the fundamental ideas of information theory and was initially proposed by B. Ryabko in 2012. The main idea of the method is its ability to evaluate the performance by using the “Computer capacity” characteristic. To determine the “Computer capacity” it is necessary to solve the characteristic equation which construction just needs the information of the architecture of investigated processor (instruction list, execution time of instructions, specification of all types of used memory etc.). During the work we investigate the ARM processors based on ARM7TDMI-S and ARM920T cores. The various features of implementation of ARM instructions which are accounted in construction of characteristic equations are described in detail. The results of applying the method to ARM processors are compared with those corresponding results for Intel processors obtained in previous papers and with CoreMark performance evaluation results. The result of applying the method shows the numbers similar to the CoreMark values. In the course of comparison, we show that the method may be used equally with benchmarks and allows us to compare processors with fundamentally different architectures (Intel and ARM), it does not require the presence of a working model of the processor, and needs only the descriptions of its architecture.
