This phase tests the operation and instruction set of the microprocessor.
Test 1 - checks the extract field instruction.
Test 2 - checks the insert field instruction.
Test 3 - checks the move block instruction.
Test 4 - checks the swap interlocked instruction.
Test 5 - checks the Test bit instruction.
Test 6 - checks the Save and Restore register instructions.

Test Number: 1
Function: This test checks the extract field instruction
Procedure: Perform the instruction for all widths and offsets.
Hardware Tested: The WE 32XOO Microprocessor is tested.
Data Returned: The failing test number (last number displayed on the system console prior to
failure) is returned.
Notes: The results of the test are confirmed by comparison to a generated hash sum
which contains all of the intermediate results. Register r7 contains the hash
value that is generated by adds and rotates.
