ABSTRACT:
Decoding circuitry and a method supplying an immediate field that is issued from a decoder. A macroinstruction is supplied to the decoding circuit, which generates a first micro-operation that includes a first aliasing field and a first immediate field. The first aliasing field indicates the source of the micro-operation that will eventually be issued from the decoder. If the source is the first immediate field, then the alias field is further examined to determine the interpretation to be placed upon the data. The data may be interpreted literally, or as an address into a constant ROM, thereby providing an ability to output wide, 32-bit immediate data from a narrower, 9-bit input addresses. Additional sources for immediate data include macro-alias registers, macro-branch information, and micro-branch information.
