20120166742 | System and Method for Contention-Free Memory Access - A memory control unit of a turbo code decoder includes a buffer having a plurality of storage slots, a buffer control operatively coupled to the buffer, a router operatively coupled to the buffer control and to a plurality of data sources, and a conflict detection unit operatively coupled to the router, to the buffer control, and to the plurality of data sources. The buffer temporarily stores information intended for storage in a memory bank. The buffer control determines a number of available storage slots in the buffer. The router routes data from the data sources to the buffer control. The conflict detection unit initiates a temporary halt of some of the data sources when the number of available storage slots is insufficient to store all of the data from data sources attempting to access the memory bank. | 06-28-2012 |
