<p>A microcoded processor (10) for use in a distributed processing telex exchange to time share process each termination connected to the processor is disclosed. The processor [10) executes selected signaling routines for each termination. The processor contains a sequence file (60) that outputs the address of the next termination to be time share processed; a constant (64) and a variable (66) data file which contains data needed to execute the selected signaling routine for each termination; and a program re-entry file (62) to control the time share execution of each signaling routine. At the end of each time share interval, the program counter contents are stored in the re-entry file (62) location associated with the termination just processed. To enable high-speed processing, two high-speed cache memories (72, 74). one for the data from the constant file (64) and one for the data from the variable file (66). are also used. Program execution continues uninterrupted at the end of each time share interval.</p> |
