Phase #8 Tests
Math Accelerator Unit (MAU) (bmau3_tst)
Normal
This phase tests all of the possible MAU operation codes.
Tests 1 through 8 - check the CMP, CMPS, CMPE, and CMPES operation
codes.
Tests 9 and 10 - check the add and subtract operation codes.
Tests 11 through 13 - check the multiply, divide, and REM operation codes.
Tests 14 - checks the NEG operation code.
Tests 15 - checks the ABS operation code.
Tests 16 - checks the SQRT operation code.
Tests 17 through 21 - check the RTOI, ITOF, DTOF, FTOD and FTOI
operations.
1 second
None
The Negative (N), Zero (Z), Result Available (RA), and Partial Remainder (PR)
bits are tested during this test phase.
Tests Numbers: 1 through 8
Function: These tests check the CMP, CMPS, CMPE, and CMPES operation codes.
Procedure: Set operandI and operand2 to 123.0.
Run each compare instruction checking for equality.
Set operandI to 100.0.
Run each compare instruction checking for inequality.
Hardware Tested: The WE 32X06 MAU is tested.
Data Returned: The failing test number (last number displayed on the system console prior to
failure) is returned.
Notes: None
