Instruction Coding
Table
This section tabulates the detailed coding of all OakDSPCore instructions, including the
number of cycles and the number of words.
The instructions are ordered according to the instruction group. Some of the codes are
organized in subgroups. Following each subgroup appears a list of instructions that use
the code of this subgroup and the encoding of the XX..X field for each instruction. Notice
that the same instruction may appear in several subgroups, depending on the address-
ing mode or operand usage. See Table 7.
