Programmer Bootstrap Loading System

摘要

This report describes a programmable bootstrap loader device for loading or transferring programs into the main memory of a computer system includes a processor-peripheral interface for decoding instructions of the computer system, and for generating control signals to operate peripheral equipment coupled to the system. An alterable or programmable memory stores a set of instructions which together make up a bootstrap loader program, the alterable memory being non-volatile in the program stored therein is not lost when power to the system is shut off. An alterable memory access circuit, coupled between the processor-peripheral interface and the alterable memory, enables discrete instructions of the stored bootstrap loader program to be selectively altered by a system operator.
