Individual Test Descriptions

These are the tests performed by MemScope as they appear on the menu. A short description follows:

Test 1 Walking 1’s Test
Use a walking ones address pattern to test address bits.

Test 2 Address Test
This test will write each address location on memory with its own address once is finish will verify each of them for addressing errors

Test 3 All 1’s and 0’s Test
Will use the cache memory to write patterns of all 1’s and 0’s until memory is full and will detect obvious errors.

Test 4 8-Bit Pattern Test
Similar to test 1 but instead of moving 1 bit pattern it will move an eight bit pattern.

Test 5 Random Data Test
This test will set a random number as a pattern for walking 1’s and 0’s, contrary to test 1 or 4. By selecting a different width in the pattern, the test will find more complex or hard to detect errors on memory.

Test 6 Block move
Memory it segmented in 4 Mb blocks and moved with instruction movsl. Once finish it will verify the data patterns written on each block for consistency.

Test 7 32 Bit Shifting Data Test
Using an algorithm that changes the data pattern one bit to the left on every pass or loop. A total of 32 passes will use all data patterns but the downside is the time required for.

Test 7 Random Data Sequence Test
Random numbers are written in sequence into all memory banks. Then, using a key for the random numbers duplicates the sequence written in memory which is compared with the original sequence.
