Abstract
A single chip microcomputer formed on a semiconductor substrate includes a central processing unit, a ROM storing therein a program for operating the central processing unit, a digital signal processor, and a multi-port RAM. The digital signal processor develops an outline font on the multi-port RAM in accordance with a program stored in a storage unit provided in the digital signal processor. This eliminates the necessity of development of an outline font by the central processing unit and allows high speed execution of such development of an outline font. Further, the central processing unit and the digital signal processor can operate in a parallel relationship.
