摘要: A network protocol and interface using direct deposit messaging provides low overhead communication in a of multi-user computers. This system uses both sender-provided receiver-provided information to process received messages data directly memory conditionally interrupt host processor based on control information. Message processing is separated into delivery, which bypasses the operating system, message actions may or not require interaction. In this protocol, includes an indication operation desired by sender, operand specified sender refers some stored at receiver. The receiver ensures that action permitted then, if permitted, performs according state be wherein operands specify values for use various addressing modes including direct, indirect, post-increment index modes. also generating interrupt, are used, combination with state, determine whether requires immediate delayed action. register other
