Abstract:
1. A data processing system comprising: a data processing module configured to perform a data processing function and interface with other data processing systems using data packets having a first protocol format including actual data and control data for data transfer; and a data interface module coupled to a data bus and the data processing module, the data interface module configured to convert data packets having the first protocol format to data packets having a second protocol format, to output the data packets having the second protocol format to the data bus, to convert data packets having the second protocol format to data packets having the first protocol format, and to transfer the data packets having the first protocol format to the data processing module, wherein the data interface module includes, a write FIFO configured to sequentially store the data packets having the first protocol format received from the data processing module and to retrieve the stored data packets based on a first in first out (FIFO) method, a protocol interface coupled to the data bus, the protocol interface configured to convert data packets having the first protocol format into data packets having the second protocol format and to transfer the data packets having the second protocol format to the data bus, the protocol interface is further configured to convert data packets having the second protocol format received from the data bus into data packets having the first protocol format, and a read FIFO configured to sequentially store the data packets having the first protocol format received from the protocol interface and to retrieve the stored data packets based on the FIFO method to provide the retrieved data packets to the data processing module.
