PROBLEM TO BE SOLVED: To provide a system and a method for communicating command parameters between a processor and a memory flow controller. SOLUTION: This application utilizes a channel interface as a main mechanism for communication between the processor and the memory flow controller. The channel interface provides a channel for executing communication with, for instance, a processor facility, a memory flow control facility, a machine status register, and an external processor interrupt facility. When data to be read from a corresponding register by a blocking channel are not usable or there is no writing space in the corresponding register, the processor is brought into a low-power "stall" state. When the data are made usable or a space is released, the processor is automatically called via communication on the blocking channel. COPYRIGHT: (C)2007,JPO&INPIT
