Abstract: A system for mapping control and user data includes a direction scanner, an address calculator, a collision detector, a buffer, and a mapper for mapping control and user data from a first memory to a second memory. The direction scanner determines the highest priority value of to a code word index. The address calculator calculates start and end addresses of the highest priority value. When an address from an address range, defined by the start and end addresses, is already mapped to other control data, the collision detector detects a collision and generates feedback data. The address calculator outputs modified start and end addresses based on the feedback data. When no collision is detected, the address calculator outputs the modified start and end addresses to the buffer. The mapper then maps the control and user data to the modified start and end addresses in the second memory.
