Abstract
A system on chip, SoC, comprising two or more data sources, a memory unit, a memory control unit, and a processing unit. Each of the data sources is capable of providing a data stream. The memory control unit is arranged to maintain, for each of the data streams, a buffer in the memory unit and to route the respective data stream to the processing unit via the respective buffer. Each of the buffers has buffer characteristics which are variable and which comprise at least the amount of free memory of the respective buffer. The memory control unit is arranged to allocate and de-allocate memory regions to and from each of the buffers in dependence of the buffer characteristics of the respective buffer, thereby allowing for re-allocation of memory of the memory unit among the buffers.A method of operating a system on chip is also described.
