The WC34000 Computer
The WC34000 is a hypothetical machine designed to resemble the MC68000 but
simplified in ways intended to make it simpler to work with in various
course projects. The main simplification is that while the MC68000 can
manipulate byte, word or long word operands, the WC34000 only operates
on word length operands. This simplifies the descriptions of the behavior
of many of the machines instructions. More importantly, by eliminating
the need for the operand length specifications included in many MC68000
instructions, this change relieves the squeeze on space in the operation
field and makes it possible to greatly simplify the instruction set
encoding. This document describes the architecture of the WC34000.
Additional information about the use of the WC34000 is provide in
several other documents:
Detail specific to the WC34020, a variant of the machine designed
for use in an operating systems course project, are discussed in:
