Problems solved by technology

The dual-port memory can read and write data in the same address at the same time, but the dual-port memory has a large area. Since the memory occupies the largest area in the chip, when the number of data units n of a frame of data is larger, The impact of dual-port memory on the total area of ​​the chip system is greater
Therefore, the existing technology cannot meet the needs of today's low-cost chip design

Embodiment Construction

[0054] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0055] Using the pipeline structure for data processing brings about a problem: how to read the m+1th data unit to enter the pipeline while writing the first data unit, so there is no need to read and write the same data unit at the same time data within the address.

[0056] The single-port memory has only one interface. This interface can read data and write data, but the read operation and write operation cannot be performed at the same time. The biggest advantage is that the area of ​​the single-port memory with the same capacity is half that of the dual-port memory.

[0057] To sum up, one of the core concepts of the present invention is to use multiple single-port memories to realize the function of a dual-port memory with t...

Abstract

The invention provides a data processing method and a system, wherein the method is used to process frame data under an m-level assembly line structure; the frame data comprises a plurality of data units; a plurality of memories are used to store the data of the data units; the memories are single-port memories, and the data of a pth data unit and a p+mth data unit is stored in different memories, wherein m and p are natural numbers; the method comprises the following steps: a reading step: the data of the data units is sequentially read from the corresponding memories according to the numbersequence of the data units; a data processing step: the assembly line structure processes the read data by the data unit; a judgment step: judging if the data processing of the current data unit is completed, and if yes, a writing step is executed; and a writing step: the data of the current data unit is written into the corresponding memory. The invention is used to reduce the chip area under the premise of realizing a data processing function, so as to reduce the chip cost.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data processing method and system. Background technique [0002] With the increase of chip integration, complexity and functional requirements, especially the increase of multimedia applications, the requirements for memory (storage) space are also greatly increased. Especially with the increase of the size of the video display screen, the video encoding and decoding in the multimedia chip usually requires a large area of ​​memory to provide enough storage space. However, the increase of the Memory directly leads to the increase of the chip area and the increase of the system power consumption, which leads to the increase of the chip manufacturing cost. Therefore, how to use a smaller memory as much as possible to complete the required functions has become a challenge that must be faced in the design of high-performance chips. [0003] With the improvement of ...
