Abstract
A system on chip comprises a CPU, a local memory a data processing module, and a DMA controller. The DMA controller comprises a first interface to handle data transmissions, to and from the local memory, associated with an indication to the local memory of an address in local memory, and is designed to perform data writes and reads in the local memory via this interface. The DMA controller also comprises a second interface, which in response to a command received from the central processing unit, operations for writing and reading data in the local memory via the first interface. The DMA controller also comprises a third interface with the processing module to transmit to it the data read, via the first interface, in the local memory, this transmission not being associated with an indication to the processing module, by the DMA controller, of an address.
