METHOD AND SYSTEM FOR FULL RESOLUTION REAL-TIME DATA LOGGING |
摘要 |
A method and data-logging system are provided. The system includes a map-ahead thread configured to acquire blocks of private memory for storing data to be logged, the blocks of private memory being twice as large as the file page size, a master thread configured to write data to the blocks of private memory, in real-time and in full resolution, the data acquired during operation of a machine generating the data and written to the blocks of private memory in real-time, the machine including a controller including a processor communicatively coupled to a memory having processor instructions therein, and a write-behind thread configured to acquire pages of memory that are mapped to pages in a file, copy the data from the blocks of private memory to the acquired file-mapped blocks of memory. |

1. A data-logging system comprising:
a map-ahead thread configured to acquire blocks of private memory for storing data to be logged, the blocks of private memory being twice as large as the file page size; a master thread configured to write data to the blocks of private memory, in real-time and in full resolution, the data acquired during operation of a machine generating the data and written to the blocks of private memory in real-time, the machine including a controller including a processor communicatively coupled to a memory having processor instructions therein; and a write-behind thread configured to acquire pages of memory that are mapped to pages in a file, copy the data from the blocks of private memory to the acquired file-mapped blocks of memory. |
