This invention is a programmable image pipe processing architecture that offers full software flexibility to implement latest and greatest algorithms at fully hardwired performance levels. This invention achieves hardwired image pipe processing performance but offers full flexibility and programmability of software achieving the best of both hardwired and software image pipes processing.

Embodiments of the apparatus for modifying packet headers relate to a rewrite engine that represents each protocol header of packets in a generic format specific to that protocol to enable programmable modifications of packets, resulting in hardware and software flexibility in modifying packet headers. Software programs generic formats in a hardware table for various protocols. The rewrite engine is able to detect missing fields from a protocol header and is able to expand the protocol header to a maximum size such that the protocol header contains all possible fields of that protocol. Each of the fields has the same offset irrespective of which variation of the protocol the protocol header corresponds to. In a bit vector, all newly added fields are marked invalid (represented by 0), and all existing fields are marked valid (represented by 1). Software modification commands allow data to be replaced, removed and inserted.

The invention discloses a method for applying plug-in technology to data filtering of information distribution software. The method includes the following steps: defining type identifiers of all types of information in a system, and pointing out the information type of data when an information source side sends the data and a user side subscribes for the data; defining identifiers of all types of subscription conditions in the system, and pointing out the subscription conditions in a subscription request of the user side; defining data structures of the subscription conditions; developing plug-in boards; and integrating the software and calling procedures. According to the method, the plug-in technology is adopted, reasonable plug-in interfaces and calling conventions are designed, plug-in dynamic loading and calling mechanisms are adopted, and then the condition matching and filtering functions of the information distribution software are achieved. When new information types are added into the system, a host program of the information distribution software does not need to be changed, the coupling degree between software modules can be improved beneficially, flexibility and expansibility of the information distribution software can be improved, and therefore applicability of the information distribution software can be improved.

The invention discloses a realization method of a real-time operating system of component-based hardware. The method comprises the following steps of: firstly, dividing the real-time operating system into two parts including a hardware inner core and a software interface; then, realizing the communication of a task manager, an interruption manager, a counting semaphore manager, a mutual exclusion semaphore manager and a message queue manager of the real-time operating system by component-based manner in the hardware inner core; enabling the hardware inner core to be communicated with software by a register interface module; synchronizing all the managers by a controller lock; enabling the mangers to be communicated by standard inter-mould command interface buses; and finally, realizing an inter-processor counting semaphore manager and an inter-processor message queue manager and realizing the hardware inner core of a multiprocessor real-time operating system. According to the realization method, the inner core of the hardware real-time operating system is realized by a component-based manner so that the cuttability and the expandability of the system are improved greatly and the flexibility of the software is realized by the real-time operation of the hardware.

Embodiments of the apparatus for handling large protocol layers relate to an implementation that optimizes a field selection circuit. This implementation provides software like flexibility to a hardware parser engine in parsing packets. The implementation limits a size of each layer and splits any layer that exceeds that size into smaller layers. The parser engine extracts data from the split layers just as it would from a non-split layer and, then, concatenates the extracted data in a final result.

The invention discloses a method and a device for displaying data in a database. The method comprises the following steps: receiving user-defined configuration information; based on the user-defined configuration information, obtaining the data structure of a treelike node, wherein the data structure comprises the database objects in a database relevant to the treelike node and the relationship between the database objects; displaying the relevant content of the treelike node and the database. The invention can improve the flexibility of application software and lowers the development cost ofapplication software.

The invention relates to a method for realizing a partly reconfigurable aerospace SoC, by defining a dynamic system and a static system in the SoC, and carrying out different designs on the two systems, the system can be configured on the FPGA during the operation of the system Part of the logic is reconfigured, while the logic function of the unconfigured part does not change, so that the dynamic part can be reconfigured with both software flexibility and hardware efficiency, which can effectively solve the problem that the existing SOC internal functions and structures cannot At the same time, the configuration bit stream can be periodically refreshed through partial reconfiguration technology to prevent single event flipping of the configuration bit stream, improve the reliability and fault tolerance of the SOC, and make the function change of the SOC more flexible.
