Honeywell CC-TDOR01 Channel output card

The floating point unit (FPU) of the MC68040 microprocessor chip is supported in 167Bug. For MVME167Bug, the commands MD, MM, RM, and RS have been extended to allow display and modification of floating point data in registers and in memory. Floating point instructions can be assembled and disassembled with the DI option of the MD and MM commands.

Your program must make sure that there is an exception stack frame in the stack and that it is exactly the same as the processor would have created for the particular exception before jumping to the address of the exception handler.

When entering data in single, double, extended precision

or packed decimal format, the following rules must be observed: 1. The sign field is the first field and is a binary field.

2. The exponent field is the second field and is a hexadecimal field.

3. The mantissa field is the last field and is a hexadecimal field.

4. The sign field, the exponent field, and at least the first digit of the mantissa field must be present (any unspecified digits in the mantissa field are set to zero).

5. Each field must be separated from adjacent fields by an underscore. 6. All the digit positions in the sign and exponent fields must be present.

Scientific Notation

This format provides a convenient way to enter and display a floating point decimal number. Internally, the number is assembled into a packed decimal number and then converted into a number of the specified data type. Entering data in this format requires the following fields: An optional sign bit (+ or -). One decimal digit followed by a decimal point. Up to 17 decimal digits (at least one must be entered). An optional Exponent field that consists of: An optional underscore. The Exponent field identifier, letter “E”. An optional Exponent sign (+, -). From 1 to 3 decimal digits.
