Computer organization for allowing dynamic user microprogramming

Abstract

The concept of allowing the computer user to modify the virtual machine being emulated by a microprogram controlled computer is not new. Schemes for implementing this typically include the definition of a standard virtual machine (the <u>base machine</u>) in read-only control storage, and the provision of some writable memory to contain user-written microroutines for the duration of the user job. Alternation of a computer instruction set by the temporary addition of microroutines to the system repertoire for emulation of new instructions is known as <u>dynamic user microprogramming</u>.
