Overview

Allocates memory for stress test

Discussion

This module is used to check the memory bandwidth of the target. At instantiation time you specify the size of the memory buffer (memSize) and in which heap it should be allocated (memHeap). Then at run time, the module writes a block counter value into every value of the array. It repeats this blockWriteCount times per block process. That is, every time the processing function is called, the module performs a total blockWriteCount*memSize memory write operations. All write operations write the current value of the block counter.

Type Definition

typedef struct _ModuleMemoryLoading
{
    ModuleInstanceDescriptor instance;            // Common Audio Weaver module instance structure
    INT32 blockWriteCount;                        // Number of iterations to repeat the memory block write
    INT32 memSize;                                // Memory size of the buffer in words
    INT32 memHeap;                                // Heap in which to allocate memory
    INT32 blockCounter;                           // Number of cycles to consumer per block process
    INT32* memArray;                              // Internal array allocated in speficied memory heap
} ModuleMemoryLoadingClass;
