Abstract: A method and apparatus used to step and correct the position of raster lines in a sinusoidal or zig-zag deflection system. By combining the magnetic flux generated with a rotation “twister” coil and a vertical deflection coil, scan lines can be uniformly spaced and separated nearly to their ends. Accordingly, the magnetic flux generated with the twister coil is adjusted going in the left to right direction then reversed in polarity and readjusted while returning from right to left. It is this controlled twister flux that combines with the linear vertical deflection flux to straighten and then step each scan line to produce an aligned raster.

Abstract: A processor having a limited amount of local memory for storing code and/or data utilizes a program stored in external memory. The program stored in external memory is configured into blocks which can be loaded individually into the local memory for execution. Queuing the individual blocks of code allows the program to be executed by the processor and also facilitates loading of the subsequent code to be executed. A semaphore system can be utilized to indicate which blocks of local memory are available/unavailable. A group of transfer parameters as queue entries allow code and data for an algorithm to be transferred between both local and external memory.
