Detailed Description
The following are specific examples of the present invention, and the technical solutions of the present invention are further described, but the present invention is not limited to these examples.
Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the modules and structures set forth in these embodiments does not limit the scope of the invention unless specifically stated otherwise.
The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
Techniques, methods, and systems known to those of ordinary skill in the relevant art may not be discussed in detail, but should be considered part of the authorization specification where appropriate.
Examples: as shown in fig. 1, which is only one embodiment of the present invention, a method for collaborative reading of a communication data multi-channel microchip includes the following steps:
s1: a structure body for storage is arranged at each virtual channel receiving position, and a nonvolatile memory is arranged at the output end of the structure body;
the virtual channels can send out a plurality of flits, and even the flits sent out by each virtual channel can be sent out by different sources, so that the flits can be obtained in disorder, a memory is difficult to set in a queue in data transmission, a storage structure body is arranged in the queue, the storage structure body has certain data receiving and outputting capacity, the structure body can be arranged in the data transmission queue to obtain the flits transmitted, and then the flits are simply arranged and then output to a nonvolatile memory, and the nonvolatile memory is used for storing the next step.
In general, there are many structures, and a plurality of structures are connected to the same nonvolatile memory
S2: when the structural body acquires the microchip, acquiring the source and the label of the microchip and the serial number of the microchip;
when executing the step S2, the flit source label is determined according to the flit sequence; for example, a first flit from a first source (A) is received by a structure and recorded as A1; a second flit from the first source (a) records the flit as A2; if a different source flit is received, it is recorded as B2.
Also, the flit sequence number includes the message length and the sequence number of the current flit located in the message. Typically, a message from a source (a) is 7 in length, i.e., 7 flits are sent consecutively, and the flit is the third in the message, then the flit is recorded as A3 (7).
It will be appreciated that the flits from one virtual channel may be from different sources, and that flits from different virtual channels must not be from the same source, so that the labels of the sources of flits obtained by different structures must be different, and that in order to prevent marking flits of different sources with the same label, i.e., the presence of A3 (7) in each structure, the structures may also be labeled, e.g., the A3 (7) flits received by structure number 1, i.e., 1A3 (7).
It should be noted that 1A3 (7) above, where "1" represents a flit received by the first fabric (or a flit received from the first virtual channel), a "represents a flit received by the first fabric and sent by the first source," 3 "represents a third flit in the message sent by the first source, and" 7 "represents a total of 7 flits in the message sent by the first source.
S3: a plurality of arrangement items are established in the structure body, and each arrangement item stores flits from the same source and sequentially outputs the flits to the nonvolatile memory according to flit serial numbers;
when step S3 is executed, the flit source number and the flit sequence number are attached to the flit output from the structure to the nonvolatile memory, that is, the data similar to 1A3 (7) is attached to the end of each sort entry when the structure is output to the nonvolatile memory.
Of course, when step S3 is performed, one sort entry of the structure stores a flit of one source and outputs the flit to the nonvolatile memory, and after a predetermined deletion time, the structure erases the stored flit data in the sort entry, so that the storage pressure of the structure is much smaller and the structure is not damaged.
S4: after the nonvolatile memory stores the flit data output by one sort entry, marking the block at the tail end of the flit data as a bad block; storing flit data output by another sort entry in a block behind the bad block;
when step S4 is executed, the flit data outputted from the two sort entries are stored with a block marked as a bad block therebetween.
S5: judging whether the block in front of the block marked as the bad block is full, if yes, marking the next block marked as the bad block, moving the content in the block behind the next block marked as the bad block backwards by one block, and erasing the mark of the marked bad block; otherwise, not executing the operation;
when executing step S5, when moving the content in the block behind the next block of the marked bad block backward by one block, moving backward by one block at a time from the last block stored with data, and continuously moving backward by one block when moving backward by the bad block.
S6: judging whether no structure body outputs flit data to a nonvolatile memory within a preset time; if yes, all bad block marks are erased, and data in blocks behind the erased bad blocks are moved forward by one block; otherwise, returning to the step S5;
here, when the data in the block after the erasure flag bad block is advanced by one block at the time of executing step S6, the forward advance is started from the forefront one block that needs to be advanced.
And when executing the step S6, when erasing all bad block marks, performing mark erasing one by one from front to back, and executing one forward movement of data in the block behind the erased bad block by one block once for each mark erasing.
S7: and outputting flit data in all blocks in a whole.
The method for collaborative reading of the micro-slices of the communication data effectively combines the reading and writing of the micro-slice messages with the Nand Flash nonvolatile memory, so that various micro-slices sent by a plurality of channels are sorted and stored, the reading of the integrity is convenient, and the cooperativity is good during the reading, and the reading of the micro-slice data of other channels is not interfered.
The present invention is not limited to the above-described specific embodiments, and various modifications and variations are possible. Any modification, equivalent replacement, improvement, etc. of the above embodiments according to the technical substance of the present invention should be included in the protection scope of the present invention.
