Abstract
A processing system including processors, peripheral slots, hardware resources, and gateway circuitry. Each processor is assigned a corresponding identifier. The peripheral slots are located within an addressable peripheral space. Each hardware resource is placed into a corresponding peripheral slot, including at least one direct memory access (DMA) device supporting at least one DMA channel and at least one general-purpose input/output (GPIO) pin. Memory protection and gateway circuitry is programmed to control access of the hardware resources only by a processor that provides a matching identifier. The memories along with hardware resources are protected against unauthorized accesses to isolate applications executed on each processor within a multicore system and hence support freedom of interference.
