Abstract

The invention provides a data conversion processing method and device, relates to the technical field of electronic information, and can solve the problem of low chip data processing efficiency causedby inconsistency of data bit width and bit width corresponding to a bus during data interactive transmission. According to the specific technical scheme, after user data is obtained, a data processing mode is determined according to the instruction type in user data, when the user data comprises a data writing instruction, bit conversion processing is conducted on to-be-written data in the data writing instruction, and therefore the bit width matched with an AXI bus can be matched; and when the user data comprises the data read-write instruction, obtaining target data according to the data read-write instruction, and performing bit conversion processing on the target data, so that the bit width matching the user data bus can be matched. The present disclosure is for data processing.

Description

technical field [0001] The present disclosure relates to the field of electronic information technology, and in particular to a data conversion processing method and device. Background technique [0002] In chip design, many IP addresses (Internet Protocol Address) interfaces are based on AXI protocol interfaces. The video decoding chip in the prior art, when realizing the information interaction between the CPU and other devices through peripheral interface chips such as DDR (Double Data Rate), will use the AXI interface for read and write control, such as the CPU reads and writes DDR data through the AXI bus, etc. . [0003] When receiving user data through the above interface, due to the diversity of user data, the bit width of the user data will be inconsistent with the bit width of the AXI protocol bus. For example, the bit width of the AXI protocol bus will be greater than the bit width of the user data , and the inconsistency between the data and the number of bus b...
