INFORMATION PROCESSING SYSTEM, PORTABLE ELECTRONIC EQUIPMENT AND INFORMATION PROCESSOR

摘要

PROBLEM TO BE SOLVED: To solve a problem that the cost of a system becomes high and the expansion of a mounting area disturbs miniaturizing and lightening in weight since conventional portable information terminal equipment requires non- volatility for string programs in addition to a volatile memory for storing data. SOLUTION: A nonvolatile memory is eliminated from the portable information terminal equipment and in a configuration making the portable information terminal equipment and a master information processor connectable through a bus, a program to be ran buy the CPU of the portable information terminal equipment is transferred from the master information processor through the bus to the portable information terminal equipment and stored in the volatile memory.
