Abstract
A data processing system that simulates operation of a processor for an application program including instruction sets is provided by this invention. To solve the problem that an instruction cycle of each of the instruction sets is performed with plurality of pipeline stages in the processor, the data processing system comprises cycle-level simulating means for simulating operation of the processor controlled by the application program in cycles of the pipeline stages. By the cycle-level or based simulation of hardware using a high-speed simulator written in a high-level language such as C language, it becomes possible to provide a simulator that maintains the same level (cycle basis) of accuracy as a conventional RTL-based simulator but that operates with between several hundred and several thousand times the simulation speed.
