What effect could this have on the design of the computer's jump instructions and addressing modes?
Indexed addressing modes add a 16-bit extension word to the instruction.
The index and stack registers allowed very advanced addressing modes.
It has improved addressing modes and support for "atomic" instructions.
This also reduced the number of addressing modes and orthogonality.
Addressing modes for load/store and branch instructions were as follows.
Note that there is no generally accepted way of naming the various addressing modes.
The Plan is a program targeted at managers, which address "long-standing modes, practices, and behaviors."
Includes complete description of registers, instruction set, and addressing modes.
There are also a number of optional instructions and addressing modes that can be selected, should a specific application require them.
