Data writing method, data reading method and first-in first-out memory

Abstract

The embodiment of the invention discloses a data writing method, a data reading method and a first-in first-out memory, and the data writing method comprises the steps: determining a target number of to-be-started writing interfaces according to a working mode of the first-in first-out memory; splitting to-be-written original data into a target number of sub-data according to the reference bit width; and writing the target number of sub-data into the first-in first-out memory through the target number of write-in interfaces. The data reading method comprises the steps of determining a target number of to-be-started reading interfaces according to a working mode of a first-in first-out memory; reading the target number of to-be-read sub-data from the first-in first-out memory through the target number of read-out interfaces; and splicing the target number of sub-data into original data. According to the invention, one first-in first-out memory is utilized to meet the requirements of different application scenes, the number of first-in first-out memories in a chip is reduced, resources are saved, the area of the chip is reduced, and meanwhile, expansion of various bit widths and depths can be carried out.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a data writing method, a data reading method and a first-in-first-out memory. Background technique [0002] First-In-First-Out (First Input First Output, FIFO) memory is a commonly used data cache unit, widely used in various chips, mainly used for caching continuous data streams and centrally entering and storing data, which can ensure The correctness of data and the realization of high-speed pipeline operation of the system. However, in different application scenarios, the bit width of the data to be processed may be different. In this case, it is necessary to add FIFO memories of different specifications. However, due to the different bit widths of the data, adding too many storage units such as FIFO memories of different specifications will lead to a series of problems such as waste of resources and increase in chip area. Contents of the invention [0003] In view of the above...
