Concurrent data caching method and structure

Abstract

The invention relates to a concurrent data caching method and structure. The concurrent data caching method includes the following steps: a step A, writing in each group of data, A1, monitoring if writing locking state cache partitions exist or not, and executing a step A2-2 if so; A2 monitoring if idle state cache partitions exist or not if not, A21, A21-1 selecting a group of idle state cache partitions and setting the idle state cache partitions to be a writing locking state if so; A21-2, writing data in cache partitions; A21-3, determining if the data is written successfully or not, and completing writing of the group of data if so; setting the cache partitions to be a filled state if not, and executing the step A1; A22, ending data writing if the idle state cache partitions do not exists; a step B, reading the data, B1, monitoring if filled state cache partitions exist or not in real time, and B11, selecting the group of cache partitions and setting the group of cache partitions to be a reading locking state if so; B12, reading cache data in the cache partitions, setting the cache partitions to be an idle state when reading is finished in the cache partitions, and executing the B1; and executing the step B1 and continuously reading the data if the reading is not finished in the cache partitions. Strict reading, writing and locking is performed on the cache partitions, and then the speed of data processing can be effectively optimized.

Description

technical field [0001] The invention relates to data acquisition technology in the field of radiation detection, in particular to a high-speed data acquisition cache method and equipment. Background technique [0002] In the high-speed data acquisition system in the prior art, each data channel is generally correspondingly provided with an independent FIFO (First Input First Ouput, first-in-first-out queue) for buffering channel data. However, in actual data acquisition, Often encounter the contradiction of high data collection rate and fast speed, but long data processing time and slow speed. When the cache capacity is large, the rate of this original data is high, which puts forward higher requirements for network reception and data processing. . [0003] Taking full digital PET as an example, figure 1 It is a schematic diagram of the data acquisition and processing flow in the all-digital PET equipment. Each channel of the detector samples and encodes the received signa...
