Patent Searching and Data


Title:
MICROCOMPUTER AND DATA RECEIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2005/066807
Kind Code:
A1
Abstract:
A microcomputer (1), which includes a central processing unit (2), a RAM (7) and a ROM (6), is formed in a single semiconductor chip. The ROM has stored therein an operating system, application programs, and TCP/IP processing programs that can be invoked from the application programs to be executed. The TCP/IP processing programs include processing programs of connection request, event waiting, data transmission and disconnection. When the central processing unit requires packet data by reading a portion of the packet data into the RAM in response to a data reception interrupt during execution of a processing program of event waiting, it starts up from the event waiting state to execute an application program to further import the corresponding packet data into the RAM.
