Problems solved by technology

[0006] Therefore, there is the following problem in the existing information communication in units of information packets, that is, since the number of information packets storing information in a packet unit does not change with the communication mode, information cannot be stored even in an empty state. During the process, other access cannot be performed, and the host computer for information communication refuses to accept the phenomenon

Embodiment Construction

[0020] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following descriptions are examples of the present invention, but the present invention is not limited to the following descriptions.

[0021] One example of the communication controller of this embodiment will be described below. figure 1 Yes is a block diagram showing a device controller formed in the terminal device. Among them, the device controller as a communication controller is installed in a terminal device such as a printer, and the terminal device is connected to a host computer (hereinafter referred to as the host computer). The central processing unit (CPU: Central Processing Unit) of the host computer and the central processing unit (CPU) of the terminal device CPU) communicates through the device controller. In addition, the terminal device and the host computer communicate with each other by connecting with a USB cabl...

Abstract

PROBLEM TO BE SOLVED: To provide a communication controller and a communication method in which a status of a reception rejection is suppressed from occurring with a communication host when communicating information in a packet.SOLUTION: The communication controller receives information corresponding to a plurality of communication modes with different information quantities contained in one packet for the unit of a packet, temporarily stores the information and transmits it later, the communication controller is provided with a storage means for temporarily storing the received information and a control means for controlling the number of packets to be stored in the storage means in accordance with the communication mode and in the case of a communication mode that a plurality of packets can be stored in the storage means, the control means temporarily stores the plurality of packets in the storage means.

Description

technical field [0001] The present invention relates to a communication controller and a communication method, in particular to a communication controller and a communication method for performing information communication in the form of an information packet. Background technique [0002] Conventionally, when connecting a computer and a peripheral device, an interface for peripheral devices such as a serial interface (Serial Interface) or a parallel interface (Parallel Interface) is used for connection. In addition, serial interfaces such as USB (Universal Serial Bus) and IEEE1394 have emerged as interfaces for connecting a plurality of various peripheral devices together, and the standardization and generalization of interfaces has become a trend. [0003] In the information society in recent years, due to the need for high-speed and large-capacity data communication, the USB2.0 standard has been developed, which is compatible with the existing USB1.0 standard (USB-IF: USB...
