Extended instruction set for packet processing applications
View Patent ↗A software program extension for a dynamic multi-streaming processor is disclosed. The extension comprising an instruction set enabling coordinated interaction between a packet management component and a core processing component of the processor. The software program comprises, a portion thereof for managing packet uploads and downloads into and out of memory, a portion thereof for managing specific memory allocations and de-allocations associated with enqueueing and dequeuing data packets, a portion thereof for managing the use of multiple contexts dedicated to the processing of a single data packet; and a portion thereof for managing selection and utilization of arithmetic and other context memory functions associated with data packet processing. The extension complements standard data packet processing program architecture for specific use for processors having a packet management unit that functions independently from a streaming processor unit.
1. A software program extension for a dynamic multi-streaming processor, the software program extension stored in a computer readable medium comprising an instruction set enabling coordinated interaction between a packet management component and a stream processing component of the processor comprising:
a portion thereof for managing packet uploads and downloads into and out of memory;
a portion thereof for managing specific memory allocations and de-allocations associated with enqueueing and dequeuing data packets;
a portion thereof for managing the use of multiple contexts dedicated to the processing of a single data packet; and
a portion thereof for managing selection and utilization of one or more arithmetic functions and other context memory functions associated with data packet processing;
characterized in that the software program extension complements standard data packet processing program architecture for specific use for processors having a packet management unit that functions independently from a stream processor unit.
2. The software program extension of claim 1 wherein the dynamic multi-streaming processor functions as a data router coupled to a data packet network.
3. The software program extension of claim 2 wherein the data packet network is the Internet network.
4. The software program extension of claim 1 wherein the coordinated interaction includes conununication of requests, commands, and notifications that do not require responses.
5. The software program extension of claim 1 wherein the portion for managing packet uploads and downloads includes instructions for packet activation, packet completion, packet removal, packet identification, packet relocation, and packet update.
6. The software program extension of claim 5 wherein the packet removal and packet relocation instructions are associated with removal of a packet from memory and relocating a packet from one portion of memory to another.
7. The software program extension of claim 1 wherein the portion for managing memory allocations and de-allocations includes instructions for obtaining space in memory and for clearing previously allocated space in memory.
8. The software program extension of claim 7 wherein the memory is hardware controlled by a packet management component.
9. The software program extension of claim 1 wherein the software program extension is supported by a MIPS compatible processor architecture.
10. The software program extension of claim 1 wherein the portion for managing the use of multiple contexts includes instructions for obtaining an idle context, releasing an activated context, and for forcing nonuse of a context for predefined period of time.
11. The software program extension of claim 1 wherein the portion for managing selection and utilization of arithmetic and other context memory functions includes instructions for gathering information from memory for loading into a context, distributing information from a context into memory, selecting and accessing at least one addition function, and for selecting and accessing at least one subtraction function.
12. A software program extension for a dynamic multi-streaming processor, the software program extesion stored in a computer readable medium comprising an instruction set enabling coordinated interaction between a packet management component and a stream processing component of the processor comprising:
a portion thereof for managing packet uploads and downloads into and out of memory;
a portion thereof for managing specific memory allocations and de-allocations associated with enqueueing and dequeuing data packets;
a portion thereof for managing the use of multiple contexts dedicated to the processing of a single data packet, wherein the portion for managing the use of multiple contexts includes an instruction for forcing nonuse of a context for predefined period of time; and
a portion thereof for managing selection and utilization of one or more arithmetic functions and other context memory functions associated with data packet processing;
characterized in that the software provam extension complements standard data packet processing program architecture for specific use for processors having a packet management unit that functions independently from a stream processor unit.
