ABSTRACT:
A data processor that can perform instructions in parallel on respective fields in an operand includes a respective multiplexer for each of the respective fields. Each respective multiplexer is controlled by condition data for a particular field, preferably from an addressable storage unit. The condition may take three or more values for each field, which allows multiplexing between three or more values, reflecting a less than, equal to, or greater than relation between respective compare inputs. The inputs of the multiplexers can share read ports to a register file with more than one functional unit connected to only two read ports.
