ABSTRACT:
Techniques are described for accurately and efficiently emulating an instruction processor having a write buffer. The described techniques may be utilized to quickly develop an emulated instruction processor that provides a fully-functional write buffer interface in an efficient and elegant manner. For example, a system is described that includes a computing system that provides an emulation environment, and software executing within the emulation environment that emulates an instruction processor having a write buffer interface and a memory interface. The software emulates the instruction processor by selectively outputting a write request on the write buffer interface or the memory interface in response to an emulation control instruction embedded within an instruction stream.
