Instruction Set
This section provides an overview and detailed description of the OakDSPCore instruc-
tion set definition and coding, as well as complete information on the function of each
instruction. The pipeline method is covered briefly. The section gives sufficient informa-
tion to understand the nature of OakDSPCore programming and the capability of the
instruction set itself.
