RING BUFFER MANAGEMENT

A method is provided for managing access to a ring buffer, for at least one data transfer channel for a determined amount of data, with this ring buffer comprising a series of buffer sub-areas spaced apart by a memory address offset and ordered from a first buffer sub-area to a last buffer sub-area. A starting address is initialized from a first register storing the value of the memory address of the first buffer sub-area, and a counter is initialized from a second register storing the value of the number of buffer sub-areas in the buffer. The buffer sub-areas are successively accessed, from the first buffer sub-area to the last buffer sub-area, starting from the starting address and as a function of the memory address offset, on the basis of the value of the counter. The initialization and access steps are repeated such that the determined amount of data is transferred.
