Abstract
In a character recognition system lines of data are stored in a line memory. This data is then accessed by a hardware implemented character position detector over a special line memory bus, i.e., a LM-bus. The detector searches the memory for the margins of characters and can also perform a count of the black points or character points within the margins. The position detector is activated by a system controller over a B-bus, but once started by the controller it will run on autonomously until it has completed its task, thereby leaving the processor and the B-bus available for other functions.
