UMPIRE is a comprehensive memory test program implementing two
test algorithms developed at the University of Illinois. The
algorithms were published in June 1978 'IEEE TRANSACTIONS ON
COMPUTERS'. The University of Illinois test algorithms are the
'BOOMERANG' and the 'HALF SLOW' test routines. Also included are
two test routines I devised.
The test will automatically size the TPA and test all of memory
up the start of BDOS. There are only three control codes. A ^K
will cause the test to restart, a ^C will cause a jump to address
zero (i.e. warm boot), and a ^S will cause the program to stop or
start. The ^S function is particularlly useful in the 'SCRAMBLE'
and 'SPIRAL' routine to stop to test causing refresh verification
on dynamic memories. Another ^S will cause the test to start up
again. Both the 'SCRAMBLE' and 'SPIRAL' test routines use random
data so this is a fair test of a memory array for pattern
sensitivity.
