Example Embodiment

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] figure 1 , figure 2 and image 3 It has already been described in detail in the background art.

[0033] Figure 4 It is a structural schematic diagram of the ping-pong buffer device proposed by the present invention. The main input of the ping-pong buffer device involved in the present invention is: input data and additional information of the input data. like Figure 4 Shown, the ping-pong cache device that the present invention proposes comprises:

[0034] The data additional information analysis module is used to analyze the input data additional information, input the analysis result to the additional information input selector, and simultaneously generate full normal jump conditions and additional information abnormal jump conditions to output to the write jump condition processing module.

[0035] The additional informati...

Abstract

The device comprises a module for analyzing additional message about data, a selector for inputted additional message, an analyzing module for inputted data, a selector for write cache, a module for processing write jump condition, a ping-pong cache module, a selector for outputted additional message and a selector for read cache. The invention can implement caching for different type data in data flow by only using one ping-pong cache.

Description

technical field [0001] The invention relates to the field of data buffering, in particular to a data buffering technology for processing scattered and multi-type data reception and classified and quantitative sending. Background technique [0002] The ping-pong buffer (PingPong Buffer) mechanism is a commonly used buffer method to increase data bandwidth. It can be used in any system that requires simultaneous read and write operations, such as data reorganization caches in switch and router systems, or data bulk transfers in computer systems. [0003] figure 1 is a schematic diagram of a common cache. like figure 1 As shown, this is an ordinary buffer (buffer), assuming that its input (An) and output (Dn) have data unit processing (batch processing), within each data unit time (we call it a time slot) , zero (An=0) or one (An=1) new data unit will be input, and there may also be zero (Dn=0) or one (Dn=1) data unit output; this means that in each time slot, there are tw...
