Problems solved by technology

Therefore, due to the impedance dispersion between the signal lines, the adjustable phase is limited, so the upper limit of the operating frequency is specified.
In addition, when a nonvolatile memory is used as a memory connected to a high-speed data transfer interface, it will take time to program these memories in a control system using EEPROM and flash memory.
In this way, for example, when downloading information from the server via the network and reading the downloaded information, a dedicated buffer memory is required, or the transfer speed on the network is significantly limited.

Embodiment Construction

[0025] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The same symbols in the drawings indicate the same or corresponding parts.

[0026] figure 1 is a block diagram showing a data processing system according to an embodiment of the present invention.

[0027] refer to figure 1 , the data processing system 1 is installed in a network terminal such as a home. The data processing system 1 receives a signal transferred from the coupling switch 2 at a transfer rate of 12 Gbps. The coupling switch 2 converts the 48Gbps signal to 12Gbps, and also transfers the signal to other households and the like.

[0028] The data processing system 1 includes a coupling switch 4 whose coupling switch 14 and a demultiplexer 16 are integrated into one chip; a signal processor 6 (processor, etc.) whose frequency is converted to 3 GHz from the demultiplexer 16 ); between the demultiplexer 16 and the signal processor 6, a signa...

Abstract

A first feature of a data processing system is in that, in a data transfer path including a plurality of signal lines used for data transfer, a phase control is performed independently for each of the signal lines. A second feature is in that data is selectively transferred from a coupling exchange to a signal processor or a signal memory. A third feature is in that the signal processor, the signal memory and the coupling exchange are coupled to each other. By the features, the phase margin in the transfer data and clocks is widened and high speed transfer can be realized. Since data can be directly written in the signal memory, the signal processor can be efficiently used. Further, efficiency in processing and transfer of signals is improved.

Description

technical field [0001] The present invention relates to a data transfer interface mounted on a system LSI, and more particularly to a data transfer system including a semiconductor storage device having an ultra-high-speed data transfer interface between LSIs. Background technique [0002] For example, Japanese Patent Application Laid-Open No. 5-342118 discloses an advanced technology for improving information transmission efficiency. [0003] In this prior art data communication method, information of different natures is transmitted and received by a synchronous communication method and an asynchronous communication method. Thus, by selecting the communication method at the time of transmission according to the nature of the information to be transmitted and received, the information is transmitted and received in a manner suitable for the nature of each information. In addition, information transmission efficiency is improved by utilizing independent paths for informatio...
