(57) [Summary] A dual instruction set processor can decode and execute both a code received from a network and other codes supplied from a local memory. Thus, the dual instruction set processor can execute two different types of instructions from two different code sources and achieve maximum efficiency. A computer system with the aforementioned dual instruction set processor, local memory, and a communication interface device for connection to a network, such as the Internet or an intranet, such as a modem, executes Java code from the network, Or may be optimized for execution of non-JAVA code that has been retrieved from the network but is trusted or authorized but has been retrieved from the network. |
