LAP SUMMARY
At the completion of each lap of ECCTEST, a table of statis-
tics is displayed. It shows:
1)
For single-bit errors:
a)
number of 1-bi t errors forced
b)
number of 1-b it errors corrected
&
reported
c)
number of 1-b it errors uncorrected
d)
number of 1-bit errors corrected, but unreported
If the number of forced errors
=
the number corrected and
re por·ted ( a= b) , then no errors have occurred.
2)
For two-bi t errors:
a)
number of 2-bit errors forced
b)
number of 2-bit errors detected
&

c) number of 2-bit errors undetected
d) number of 2-bit errors detected but unreported
