FIFO BUFFER CLEAN-UP |
摘要 |
Systems and methods are disclosed for managing data entry buffers in a data storage device. A memory of the data storage device includes one or more data input ports. The device further includes a controller configured to receive a data entry over one of the data input ports and store the data entry in a first data structure (e.g., a FIFO data structure). The data entry is stored in the first data structure among other data entries received over various data input ports. The controller stores a data entry corresponding to the data entry stored in the first data structure in a second data structure. Entries in the second data structure include a valid bit field and one or more condition fields. The controller indicates, using a valid bit field of the second data structure data entry, that the corresponding data entry stored in the first data structure is valid. |

1. A device comprising:
a controller configured to:
receive a first data entry over a first input port;store the first data entry in a first data structure in a memory;store a second data entry corresponding to the first data entry in a second data structure in the memory, wherein the second data structure is separate from the first data structure, and wherein entries of the second data structure include a valid bit field; andindicate, using the valid bit field of the second data entry in the second data structure, that the first data entry in the first data structure is valid. |
