Abstract

The network process device and method comprise: an interface unit with multiple channels to send and receive message, a micro-engine unit with multiple micro-engines, and an address mapping unit with lots registers for segmental address mapping. This invention fills the message into buffer on micro-engines according to mapping, and introduces convenience to software development.

Description

technical field [0001] The present invention relates to a network processing unit (NPU: Network Process Unit), specifically a network processing device and method. Background technique [0002] Network Processing Unit (NPU: Network Process Unit) is a programmable or configurable semiconductor device designed and optimized for processing network data (data packets). NPU optimizations include hardware and instruction sets to support high-speed packet classification and packet modification. The main function of the network processing unit is to offload the data transmission and processing tasks specific to network applications from the general-purpose processor, thereby greatly speeding up the processing and transmission of information packets. A network processing unit generally consists of a core processor (such as the Strong ARM core series) and multiple micro engines (Micro engines), which concurrently and synchronously complete the processing of a data packet. In the net...
