Abstract
A method and an apparatus for operating a circulating memory that can be addressed by a write pointer and/or a read pointer are disclosed. The method and the apparatus are distinguished by the fact that a jump of the write pointer and/or of the read pointer from the end of the memory to the beginning of the memory and/or vice versa is signaled.
Claims11
A method for operating a circulating memory, which comprises:
- addressing a memory having a beginning and an end, with at least one of a write pointer and a read pointer;
- outputting a jump signal upon an occurrence of a jump by at least one of the write pointer and the read pointer from the end of the memory to the beginning of the memory;
- and
- configuring the jump signal so that it is recognizable by an instruction of a program using the memory.
1 more element
In a circulating memory addressed by at least one of a write pointer and a read pointer and having a beginning and an end, an apparatus for operating the circulating memory, comprising:
- a signaling device for generating a jump signal signaling the occurrence of a jump by at least one of the write pointer and of the read pointer from the end of the circulating memory to the beginning of the circulating memory, said jump signal configured to be recognizable by an instruction of a program using the circulating memory.
