CPU BUILT-IN LSI AND OPTICAL DISK UNIT USING THE SAME, AND LSI DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a CPU built-in LSI where the use capacity of an RAM is reduced and an optical disk device using it by partially integrating software recorded in an external memory in an RAM. SOLUTION: In a CPU built-in LSI 101, an RAM 103 is provided with: a software storage area 108 for storing software read by module units from an external memory 107; and an entry table 109 for storing entry including at least the location information and size information of a module stored in the software storage area 108. A CPU 102 decides the storage position of the module to be read from the external memory 107 to the software storage area 108 by referring to the entry table 109 according to an integration position investigation program 121.
