摘要： A mailbox message system is coupled between a processor having a mailbox and one or more peripheral devices or circuits communicating information to the processor. The mailbox message system in the present invention reports events which occur in the peripheral devices or circuits to the mailbox within the processor to be serviced by the processor. The mailbox message system receives inputs from the processor indicating which events are allowed to be currently serviced by the processor and stores these inputs in a first memory. The mailbox message system further receives unique signals representing distinct events from the peripheral devices and stores these signals in a second memory. The generated events which are pending service in the second memory are then compared with the allowed events in the first memory. When a match exists, a message is encoded and transmitted to the mailbox of the processor indicating that the processor has an event to be serviced. The processor then must service all the pending events in the second memory.

摘要： A data processing system provides a method and apparatus for managing a shared resource between multiple processors. The data processing system includes a first processor for producing, or supplying, available sections of the shared resource, and a second processor for consuming, or allocating, the available sections within the system. The first and second processor share a memory containing a circular queue, a resource queue, for referencing available shared resource sections. The resource queue is initialized by storing a pointer to an available shared resource section in each entry of the resource queue. The second processor consumes an available section of shared resource by removing a resource pointer from a resource queue entry and sending a message signal to a mailbox message subsystem of the first processor. The first processor produces an additional section of available shared resource by servicing the resource message signal and adding a pointer to the additional shared resource section in an empty resource queue entry.

摘要： A device, system and method of data compression are provided. The invention includes a receiving module that may be a memory module. The invention also includes a pointer module storing a pointer to a location within the receiving module. The invention allocates a receiving space within the receiving module and associates the pointer with the receiving space. The pointer may be associated with the beginning of the receiving space. The invention compresses a first data block and directs the compressed first data block to the receiving space at the location indicated by the pointer. The invention further associates the pointer with the location in the receiving space contiguous with the received compressed first data block. The invention compresses a second data block and directs the compressed second data block to the location within the receiving space indicated by the pointer. The invention compresses data as contiguous compressed data blocks.

摘要： A method of enabling state save and debug operations for co-routines for first failure data capture (FFDC) in an event-driven environment. A stack management utility allocates space for a context structure, which includes a state field, and a stack pointer in a buffer. A context management utility initializes a first context structure of a first co-routine and saves a state of the first context structure in response to an execution request for a second co-routine. The context management utility sets a second context structure as a current context. When execution of the current context is complete, the context management utility restores the first context structure of the first co-routine as the current context. If the state field is not set to a valid value, a state save function “state saves” all allocated co-routine stacks and context structures, restores the entire system to a previous valid state, and restarts operations.
