Bus interface devices and method

Abstract

A method for realizing data transmission on bus interface includes confirming frequency n of sectional transmission according bus bit width ratio of the first system with low bit width bus to the second system with high bit width bus, receiving n numbers of information from the first system and piecing them together to send them to bus of the second system when information stream is from the first system to the second system or otherwise receiving information from the second system and disconnecting it to be n numbers of information being sent to bus of the first system.

Description

technical field [0001] The invention relates to bus interface technology, in particular to a bus interface device and method. Background technique [0002] With the development of information processing technology, general information processing equipment is more and more recognized and widely used. For example, various processor systems that provide solutions to different problems are made into general-purpose chips according to certain standard specifications. As long as the bit width of the address bus and the bit width of the data bus of the processor chip and the application system match each other, communication between the two can be realized. Therefore, these general-purpose processor chips are widely used in various systems. [0003] Locosto is a general-purpose single-chip baseband processor integrated with digital baseband and digital radio frequency launched by Texas Instruments (TI). As a new single-chip baseband processing system, this product not only provi...

Problems solved by technology

However, when the data bus width of the system exceeds 16 bits and the address bus width exceeds 24 bits, Locosto cannot implement data transmission with the system

For example, Locosto cannot be applied to a 32-bit system with a data bus width of 32 bits and an address bus width of 32 bits due to the bus width mismatch.

[0012] Similarly, when the data bus widths of any two systems do not match, the address bus widths do not match, or the data and address bus widths do not match, information cannot be transmitted between the two systems
