Lairts Pixel Data Formatter.

摘要

The Oklahoma State University Electronics Laboratory designed a system to assemble the asynchronous data from a pixel array together with the required housekeeping (HSKP) data and format these data into a synchronized PCM bit stream for magnetic tape recording. This report covers in detail the design of the pixel data storage system and its entry into the bit stream. The format requires a minor frame length of 132 words and a subframe length of 128 frames. There was very little available information on the amount of HSKP data that would be required. However, very simple modifications to the formatter would accommodate extra HSKP words and they are relatively easy to format.
