Techniques are described for loading decoded instructions and super-set instructions in a memory for later access. For loading a decoded instruction, the decoded instruction is a transformed form of an original instruction that was stored in the program memory. The transformation is from an encoded assembly level format to a binary machine level format. In one technique, the transformation mechanism is invoked by a transform and load instruction that causes an instruction retrieved from program memory to be transformed into a new language format and then loaded into a transformed instruction memory. The format of the transformed instruction may be optimized to the implementation requirements, such as improving critical path timing. The transformation of instructions may extend to other needs beyond timing path improvement, for example, requiring super-set instructions for increased functionality and improvements to instruction level parallelism. Techniques for transforming, loading, and executing super-set instructions are described.
