2.4 INSTRUCTION SET
2.4.1 General Instruction Format
Figure 2-11 shows the general format of a Series 32000
instruction. The Basic Instruction is one to three bytes long
and contains the Opcode and up to two 5-bit General Ad-
dressing Mode (‘‘Gen’’) fields. Following the Basic Instruc-
tion field is a set of optional extensions, which may appear
depending on the instruction and the addressing modes se-
lected.
Index Bytes appear when either or both Gen fields specify
Scaled Index. In this case, the Gen field specifies only the
Scale Factor (1, 2, 4 or 8), and the Index Byte specifies
which General Purpose Register to use as the index, and
which addressing mode calculation to perform before index-
ing.
Following Index Bytes come any displacements (addressing
constants) or immediate values associated with the select-
ed addressing modes. Each Disp/lmm field may contain
one of two displacements, or one immediate value. The size
of a Displacement field is encoded within the top bits of that
field, as shown in Figure 2-13, with the remaining bits inter-
preted as a signed (two’s complement) value. The size of an
immediate value is determined from the Opcode field. Both
Displacement and Immediate fields are stored most-signifi-
cant byte first. Note that this is different from the memory
representation of data (Section 2.2).
Some instructions require additional ‘‘implied’’ immediates
and/or displacements, apart from those associated with ad-
dressing modes. Any such extensions appear at the end of
the instruction, in the order that they appear within the list of
operands in the instruction definition (Section 2.4.3).
