Abstract
Methods and apparatus for registering and handling access violations of host memory. In one embodiment, a peripheral processor receives one or more window registers defining an extent of address space accessible from a host processor; responsive to an attempt to access an extent of address space outside of the extent of accessible address space, generates an error message; stores the error message within a violation register; and resumes operation of the peripheral processor upon clearance of the stored error message.
