The OAL Cache Test assesses the cache and memory subsystem of a Windows Embedded CE–based device. The test can expose problems in the kernel, OEM adaptation layer (OAL) cache implementation, hardware cache implementation, and memory chips.In This Section...
This test case exercises the cache rather than the underlying memory subsystem because in steady state, each memory access should be a cache hit. If the CeGetCacheInfo function reports that the size of the cache is zero, this test case uses a 4-MB array. The step size varies throughout ...

Exercises Exercise 8.1 In less than one page, describe four everyday activities that exhibit temporal or spatial locality. List two activities for each type of locality and be specific. Exercise 8.2 In one paragraph, describe two short computer applications that exhibit temporal and/or spatial local...
In a typical implementation, the cache controller also exercises one or more control lines to acknowledge receipt of the I/O data and indicate to a main memory controller that storage of the I/O data in the main memory is not required (effectively stopping the DMA write to main memory). ...
In our SAP NW CEO exercises or project experiences we would have come across the transaction SXI_CACHE and used it extensively without even really understanding exactly what it is all about and would have even faced weird errors. Typically in real time environment when people are placed in XI ...
