TABLE DRIVEN EMULATION SYSTEM |
摘要 |
<p>A host microprogrammed data processing system includes a plurality of tables to store information coded to define a plurality of a variety of different input-output system configurations of resources required to execute input-output instructions in a corresponding number of target systems being emulated by the host system. The host system further includes emulation apparatus which includes a control store which stores microprograms for directing the system in processing input-output instructions of target programs and for verifying whether each such instruction can be executed by the host system. The emulation apparatus generates coded information indicating which one of a given number of channel program routines the host system is required to use to execute the input-output instruction using the host input-output resources. Using the information of the tables, the emulation apparatus is able to execute completely certain types of target system input-output instructions used to perform control operations.</p> |
