发明名称 DISPOSITIVO E RELATIVO METODO PER LA SCRITTURA/LETTURA DI UN REGISTRO DI MEMORIA CONDIVISO DA UNA PLURALITÀ DI PERIFERICHE.
摘要 <p>A device and method for writing/reading a piece of data in/from a memory register shared by a plurality of peripherals, each peripheral having a peripheral clock signal, when two or more of the plurality of peripherals need to write/read such piece of data at the same time, the digital device including a central unit having the memory register and a bank of SL modules in signal communication with the central unit, the bank of SL modules being designed to write/read the piece of data. The bank of SL modules comprises a plurality of writing/reading modules whose priority value ranges between maximum and minimum priority values, each module being connected to a respective peripheral, the central unit includes a multiplexer in signal communication on the one hand with the plurality of writing/reading modules, and on the other hand with the memory register, each module comprises an arbitration cell, such that the first module is identified by the maximum priority value (Prmax′) and the other N−1 modules are identified by decreasing priority values, the central unit operating at a predetermined main clock frequency to write/read the piece of data in the memory register.</p>
