Embodiment Construction

[0029] The technical scheme of the present invention will be described in detail below by taking the application of a voice (Voice) access board and a data / fax (Modem / Fax) access board of a certain product as an example. The voice (Voice) access single board and the data / fax (Modem / Fax) access single board are exactly 64-bit wide or 32-bit wide high-speed wide-bit processors and 8-bit wide low-speed interface processors in the embedded hardware system Or the example of a dedicated chip application, where there is a large amount of data transfer between the two. By applying the device of the invention, the bus data can be transmitted quickly, and the processing capacity of the system can be improved, so that the integration degree of the whole system can be increased and the cost can be reduced.

[0030] The two types of boards directly provide WAN access and LAN interfaces respectively, and at the board level, the physical layer, link layer, network layer, transport layer prot...

Abstract

A quick bus to bus transferring device consists of a central control module, a data access module, a control interface module of high speed wide processor, an access control interface module of high speed wide master / slave or direct memory, a low speed interface processor or special chip control itnerface module, an interrupt control module and a register. This invention features that the said bus to bus transferring device is arranged between the 64 or 32 digit high speed processor and the 8 digit low speed processor. When data transfer from the high speed processor to the low speed one, they are stored in the data storage area of the said bus to bus transferring device at first, and then transferred in the 8 digit width.

Description

technical field [0001] The invention relates to a device for enhancing system processing capability by increasing bus utilization bandwidth, and belongs to the field of embedded hardware design. In particular, it relates to a practical device for how to improve the system processing capability by mass data transmission between a 64-bit wide or 32-bit wide high-speed wide-bit processor and an 8-bit wide low-speed interface processor or a dedicated chip in an embedded hardware system. Background technique [0002] In an embedded hardware system, there are usually a variety of processors and dedicated chips, each of which completes different tasks, such as network protocol processing, signal modulation and demodulation processing, voice codec processing, and signal control processing. In the usual embedded hardware system design, a 64-bit wide or 32-bit high-speed wide-bit processor network processing protocol is used, and a digital signal processor or a dedicated chip is used ...
