- 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.
