Problems solved by technology

[0004] It can be seen that this method of using the ping-pong structure, that is, two single-port memories read and write in turn, takes up too much chip volume.

Embodiment Construction

[0027] Referring to Fig. 6, it is a circuit diagram of the conversion circuit for the algorithm application of the present invention. Here, only one dual-port memory is used to replace the original two single-port memories.

[0028] Referring to Figure 7, there is a rule of arithmetic sequence where the data is written to the memory for the first time: The row direction is an arithmetic sequence with a difference of 1, which is defined as Hstep; the number of data in the row direction is 20, which is defined as Hwidth; The column direction is an arithmetic sequence with a difference of Hstep*Hwidth=20, which is defined as Vstep. The beginning and the end of the two columns of data are also an arithmetic sequence with a difference of Vstep, but when the value of the sequence exceeds the threshold (Threshold=Hwidth*8-1), the difference is subtracted from the threshold. Therefore, the position of the data in the memory has a horizontal and vertical arithmetic sequence law. Using this...

Abstract

This invention discloses a storage process method for saving storage space including1, writing the first eight line image data in the original image in duplex storage 2, finding out the storage position of the first 8x8 module in the original image in the duplex storage storing the first eight line image data to read out related data and at the time when reading out a datum, the image data in the successive un-processed lines in the original image are written in the storage position with the image data read out 3, in the duplex storage storing the first eight line image data, the storage position of the next 8x8 module is found out and related data are read out. Every time when reading out a datum, the image data of successive un-processed lines are written in the places having read out data orderly, 4, judging if the image is finished, if not, it returns back to step 3, otherwise, it finishes.

Description

Technical field [0001] The invention relates to the field of image processing, in particular to a storage processing method that saves storage space. The method of the present invention includes the steps: Background technique [0002] In image processing circuits, such as JPEG (Joint Photographic Experts Group) compression circuits, data is not sequentially input to FDCT (forward discrete cosine transformer) during compression, but is input to FDCT in 8*8 blocks. So there is a circuit, here we call it a conversion circuit, to complete this format conversion of data. Normally, data is input to the conversion circuit line by line in a frame unit. After the first 8 rows of data are input, the conversion circuit is required to start reading the stored data in blocks, that is, the conversion circuit is required to output data in blocks while inputting data in rows. As shown in Figure 1, the function of the conversion circuit is generally completed with two single-port memories in a p...
