OEP. In many cases, a non-standard instruction requires multiple cycles to execute and the
operation is decomposed into a series of “standard” cycles.
The MC68060 definition of a standard instruction is:
The standard instruction group is subdivided into two classes:
The non-standard instruction group is subdivided into three classes:
Given these instruction classifications, consider Table 10-1 which defines Test 2 of the
superscalar dispatch algorithm of the OEP:
MOTOROLA
• The instruction requires a maximum of one set of extension words.
• The instruction makes a maximum of one memory access.
• The resources required by the instruction are completely specified by the operation

This class identifies those standard instructions which may be executed
This class of standard instructions may be executed in the primary OEP
Many of the non-standard instructions represent a combination of

into two standard operations: first, a standard read cycle followed by a
