MMIO data format - Support - PYNQ

Memory-mapped I/O (MMIO) and port-mapped I/O (PMIO) are two complementary methods of performing input/output (I/O) between the central processing unit (CPU) and peripheral devices in a computer. An alternative approach is using dedicated I/O processors, commonly known as channels on mainframe computers, which execute their own instructions. Memory-mapped I/O uses the same address space to address both main memory and I/O devices. … WebAdd support for these gmux > > controllers > > > > Interestingly, the ACPI table only allocates 8 bytes for GMUX, but > > we actually need 16, and as such we request 16 … lord of goblins ch 3
