Abstract
In a microprogrammed data processing pipeline system comprising a plurality of stages, microinstructions for controlling the stages are stored as templates in an addressable template micromemory store and are provided automatically and sequentially to the stages of the pipeline system. Operation microcode is introduced for a particular stage after the templates are issued from the micromemory store but before provision thereof to the pipeline system, thereby allowing a single template to control a plurality of different operations of a particular stage within the pipeline system. Provision is also made to freeze or inhibit the issuance of subsequent templates during the execution of excessively long operations in the particular stage.
