Memory Test android app

[Dhanush]

Hi,

Recently I came across Performance Test android app. I wish to understand how the memory latency test works in android app. Also what is memory read cached and memory read uncached?

From the Android General Test Info page,

Measures the time it takes for a single byte of memory to be transferred to the CPU for processing. Measured in nanoseconds, lower values are better. The test will allocate a 256 MB buffer that is then filled with pointers to other locations in the buffer, essentially a looping linked list. The order of the links is randomized within certain 1024 byte ranges.
