CoreMark includes full documentation to support your porting efforts and comprehend the run guidelines. Otherwise, you need to specify how timing is to be accomplished in the porting layer. clock(), GetSystemTimeAsFileTime(), lock_gettime()), it could take as little as 5 minutes. Therefore, if you have support for the basic functionality (i.e. How long does it take to set up and run CoreMark?ĬoreMark is easily portable to a wide range of microcontrollers and microprocessors. You can run multiple instantiations of CoreMark (a rate-type benchmark) and the source code includes a flag that will allow you to compile in code that supports a ‘create and destroy’ context functionality (where a context can be either threads or processes with shared memory or with sockets). Does CoreMark work for analyzing multicore performance? The small size of CoreMark allows it to easily fit in a processor’s cache, which means it’s suitable for testing on a very wide range of processors, from low-end to high-end devices. How does CoreMark's small size help me test a platform’s memory subsystem? Pipeline operation, memory (or cache if any) access, and handling of integer operations. What functionality of an MCU or CPU does CoreMark actually test? Comprised of several commonly used algorithms.Total binary size of no more than 16K using gcc on an x86 machine (making it more convenient to run using simulation tools).Provides a realistic mixture of read/write operations, integer operations, and control operations.Written in small and easy-to-understand ANSI C code.What are the basic features and characteristics of CoreMark? CoreMark is capable of testing a processor’s basic pipeline structure, as well as the ability to test basic read/write operations, integer operations, and control operations. For example, you might want to have the ability to ignore memory and I/O effects and focus primarily on the pipeline operation. Sometimes it’s important to isolate the CPU’s core from the other elements of the processor and focus on one key element. Why would I want to run a benchmark that doesn’t really reflect how I would use a CPU in a real application? Running CoreMark on an MCU or CPU produces a single-number score that allows users to make quick comparisons between processors. big or little endian, high-end or low-end processor). CoreMark is not system dependent, so it functions the same regardless of the platform (e.g. CoreMark is a simple, yet sophisticated, benchmark that tests the functionality of a microctronoller (MCU) or central processing unit (CPU).
