Replicating test case data into a cache and cache inhibited memory

A computer-implemented method executed by at least one processor for testing a computer processor device comprising:

• providing test data comprising a plurality of segments of test data on non-naturally aligned boundaries that together make a slice of test data, wherein the plurality of segments are non-naturally aligned where the beginning and ending of each of the plurality of segments does not line up with a cache line boundary;
• placing a first slice of test data in a cache;
• and
• placing a second slice of test data into a cache inhibited section of a main memory, wherein the second slice of test data is located a minimum distance from the first slice of test data and the minimum distance is at least the granularity of a prefetch operation in the computer processing device;
• running a test code on the first slice of test data and the second slice of test data by branching back to rerun the test code on each of the first and second slices of test data.

• placing a first slice of test data in a cache;
• and
• placing a second slice of test data into a cache inhibited section of a main memory, wherein the second slice of test data is located a minimum distance from the first slice of test data and the minimum distance is at least the granularity of a prefetch operation in the computer processing device;
• running a test code on the first slice of test data and the second slice of test data by branching back to rerun the test code on each of the first and second slices of test data comprising:
• executing test code with one or more test cases on the first slice of test data of the plurality of test data slices using a base address;
• determining if there are additional slices of test data;
• and
• where there are additional slices of test data, modifying base address with an offset to point to a second test data slice and
• branching back to execute the test code with the modified base address with the offset.
