The invention discloses an ultrasonoscopy speckle noise filtering method based on a Bayesian model. The method specifically comprises the steps that firstly, a non-local filtering model based on the Bayesian model is established; secondly, speckle noise in the ultrasonoscopy on which logarithmic compression is carried out is fitted through Gamma distribution, and then a weighting function based on the Pearson statistics distance is obtained; thirdly, the variable in the non-local filtering model is solved; fourthly, the speckle noise in the ultrasonoscopy is filtered through the solved non-local filtering model. The speckle noise in the ultrasonoscopy can be effectively filtered out, and the imaging definition of the ultrasonoscopy is improved.

The invention discloses a read-write control module and method for the same port and a dual-port memory. The read-write control module aiming at the same port can generate each stage of delay of the clock delay generation module by configuring the clock delay; the reading time sequence and the writing time sequence are regulated and controlled; therefore, the read-write pulse generation module generates a read pulse signal and a write pulse signal which are staggered in time sequence, a port read-write control signal generated by the read-write control signal generation module performs read orwrite control on the read pulse signal and the write pulse signal respectively, and a word line control signal is generated in the word line control signal generation module, wherein the read pulse signal and the write pulse signal respectively comprise a plurality of read pulses and write pulses which are periodically distributed in time; the number of read pulses and write pulses in a period can be flexibly set according to actual read-write needs, so that word line control signals in different modes are generated, data can be read and written in sequence in a clock period, the structure issimple, regulation and control are convenient and efficient, and the data has high real-time performance.
