Model Independent CPU Tests - CYBER 170 State
CU8 -
Central Processor Conunand Test tests CPU control hardware and
functional units.
*CT8 -
Random Instruction Test with CPU simulation sets up a random
instruction loop (for machine answers) and simulates the CPU.
Simulated answers are compared to machine answers for errors.
FM2 -
Floating Multiply Test checks multiply instruction and uses random
operands.
IMC -
170 Integer Multiply Test checks integer and floating point multiply
instructions using random operands.
Answers are compared to simulated
results.
FDT -
Floating Divide Test checks floating point divide instruction using
random operands.
Answer is compared to simulated results.
LAT -
Long Add Test checks add and subtract instructions using random
operands.
Answer is compared to simulated results of long add unit.
POP -
Population Counter Test checks hardware population count using random
operands.
Answer is compared to simulated results of a population
counter.
RTJ -
Return Jump Test checks both the return jump and the computed jump for
an array of jump instructions.
MYI -
65K and 131K Memory Test.checks for proper data read and write
operations from and to. central memory.
BGK -
30-Bit Instruction Test checks transfer of K field in a 30-bit
instruction.
*CMC -
Central Memory Conflict Test checks conflict situation in central
memory when many PPs make requests continuously.
*CM6 -
Central Memory Test checks stack ability to switch drive lines at
rated speed between two randomly chosen addresses.
*EJP -
Exchange Jump Test checks for exchange package errors.
*Tests CT8, CMC, CM6, and EJP are available with Hardware Initialization and
Verification (HIVS).
