3.4 System Test

CPU Temperature This subtest measures the CPU temperature to see if the cooling functions of the computer are effectively working. When the subtest starts, the following message appears on the display: CPU TEMP =

XX deg C

Throttling level = XXXXh

The number of the CPU TEMP indicates the CPU temperature at the moment in decimal notation. For example, if the number is 57, the CPU temperature is 57 degrees. The number of “Throttling level” indicates how much the CPU has slowed. This number takes one of the following three values: 0000h : The CPU is running full speed. 4000h : The CPU has slowed to 75% of its maximum speed. 8000h : The CPU has slowed to 50% of its maximum speed. The subtest displays the message five times at intervals of one minute; therefore, it takes five minutes to complete the test. The computer passes the test if the CPU temperature is less than 70 degrees at the end of the test. If the temperature is 70 degrees or more, the computer fails the test, and an error message appears on the display.

3.5 Memory Test

Cache Memory To test the 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 CPU cache memory. One test takes 3 seconds. Number of misses < Number of hits → OK Number of misses ≥ Number of hits → Fail

Subtest 05

L2 Cache Memory To test the L2 cache memory, a test similar to that for the cache memory is performed.

Subtest 06

Stress The conventional memory is provided with a write/read buffer (size 1b30 h) and creates write data in the write buffer. Subsequent to 1 MB, the data is written in the write buffer and is read into the read buffer, followed by a data comparison up to the maximum memory size.
