A multiprocessor system includes multiple processors executing multiple processes that send messages to each other. The system uses a connectionless single-window inter-process communication (IPC) protocol to avoid the high message-processing overhead of a connection-based protocol like TCP. The IPC protocol uses a central message-receive service that runs in the kernel on each processor to handle error-checking and sequence number checking and acknowledge received messages, while the single-window mechanism avoids out-of-order message reordering / buffering complexity. Since each process sending a message does not need to wait for the receiving process (which may be otherwise preoccupied or not even the focus of the receiving processor when the message is received and queued) before receiving acknowledgments, the protocol greatly reduces single-window message latency for all processes without resorting to complex connection-based multi-packet transmission windows.

The terminal deals effectively with an error occurrence in accordance with a selected one of modes that comprise a normal mode and a debug mode. The terminal comprises a mode information holder, an error detector, a mode judge unit and a initializer. The mode information holder holds mode information that indicates which mode is the selected mode. For example, the holding of the mode information is carried out ahead of supplying power to the terminal. When an error occurs in the terminal, the error detector detects the error. Then the mode judge unit judges which mode is the selected mode, by referring to the mode information so as to produce an initialization request if the normal mode is the selected mode. The initializer initializes the terminal in response to the initialization request. On the other hand, the mode judge unit does not produce the initialization request if the debug mode is the selected mode. Accordingly, the initializer does not initialize the terminal so that the terminal continues to malfunction from the error.

A semi-transparent time division multiplexer / demultiplexer that transmits low rate tributaries from one location to another using a high rate aggregate connection, while preserving substantially all of the TOH and payload for each tributary signal. Transparency of the tributary TOH is accomplished by interleaving both the TOH and the Payload of each tributary into the high rate aggregate signal. Some TOH bytes may be tunneled or re-mapped into unused / undefined TOH locations in the aggregate signal to allow transparency of the TOH without corrupting the aggregate. Errors may be handled by tunneling BIP bytes into unused / undefined aggregate locations and updating the tunneled bytes with error masks calculated at each network elements. Alternatively errors may be forwarded by using an error mask generated from the tributary BIP locations and inserting the mask into the associated aggregate BIP locations. The mask in the aggregate BIP is updated with error masks calculated at each network elements. Re-timing of TOH to a synchronized clock in the tributary framer circuits can be accomplished using controlled slips of overhead frames, whereby an entire frame is dropped or added depending on the relationship of the received clock and the synchronized clock. DCC bytes may be re-timed by adding or deleting flag bytes occurring between respective DCC packets. Re-timing of the aggregate TOH to a transmit clock may be accomplished in a similar manner.

A CPU is provided with an ability to modify its operation, with respect to error correction, as a programmable feature. An error correction scheme is selected to be performed by the error correcting circuit. The compiled program may have intentionally introduced errors which are predictably corrected by the selected error correction scheme. When a program is compiled, the program is modified by the intentional insertion of errors which would result from the execution of the program. By providing error correction schema selected during program compilation, errors can be inserted in the program code, but are handled in a predictable manner by the error correction.

A data processing apparatus and method are provided for handling errors. The data processing apparatus comprises processing circuitry for performing data processing operations, a cache storage having a plurality of cache records for storing data values for access by the processing circuitry when performing the data processing operations, and a replicated address storage having a plurality of entries, each entry having a predetermined associated cache record within the cache storage and being arranged to replicate the address indication stored in the associated cache record. On detecting a cache record error when accessing a cache record of the cache storage, a record of a cache location avoid storage is allocated to store a cache record identifier for the accessed cache record. On detection of an entry error when accessing an entry of the replicated address storage, use of the address indication currently stored in that accessed entry of the replicated address storage is prevented, and a command is issued to the cache location avoid storage. In response to the command, a record of the cache location avoid storage is allocated to store the cache record identifier for the cache record of the cache storage associated with the accessed entry of the replicated address storage. Any cache record whose cache record identifier is stored in the cache location avoid storage is logically excluded from the plurality of cache records of the cache storage for the purposes of subsequent operation of the cache storage. Such an approach enables errors to be correctly handled, prevents errors from spreading in a system, and minimises communication necessary on detection of an error in a data processing apparatus having both a cache storage and a replicated address storage.

The secure enclave may execute an interrupt service routine that causes the errant platform / CPU resource to reset without resetting the entire platform or CPU, as applicable.
