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
