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).
