3 Tests and Diagnostics

Subtest 05

L2 Cache Memory

 

 

To test the L2 cache memory, a pass-through write-read comparison of ‘5A’

 

data is run repeatedly to the test area (‘7000’:’Program’ size to ‘7000’:’7FFF’

 

(32 KB)) to check the hit-miss ratio (on/off status) for L2 cache memory.

 

Number of misses < Number of hits → OK

 

 

Number of misses ≥ Number of hits → Fail

 

Subtest 06

Stress

 

 

Data (from 1MB to the maximum MB) is written from the 16KB write buffer

 

to the 16KB read buffer and compared the data in the buffers. The read buffer

 

starts from 0001 and the comparison is continued with the following read

 

buffer addresses: 0001, 0003, 0005, 0007, 0009, 000b, 000d and 000f.
