PROGRAMMABLE SYSTEM-ON-CHIP HUB |
摘要 |
A Programmable System on a Chip Hub (PHUB) is configured to enable master processing elements within the PHUB to simultaneously access peripherals on different busses. The master processing elements include a Central Processing Unit (CPU) interface configured to decode addresses received from a CPU and configure the PHUB to connect signaling from the CPU to one of the multiple busses associated with the address. A second one of the master processing elements is a Direct Memory Access Controller (DMAC) source engine configured to conduct Direct Memory Access (DMA) reads. A third one of the master processing elements is a DMAC destination engine configured to conduct DMA writes independently of the CPU interface.
