Embodiment 1

[0028] Taking the traffic statistical data of a chip as an example, the specific processing flow of a method for managing statistical data of a chip provided by this embodiment is as follows: image 3 shown, including the following steps:

[0029] Step 31, add a set of SRAM and DRAM on the forwarding chip as the memory of the traffic statistics counter.

[0030] In this embodiment, a group of SRAM and DRAM are respectively externally mounted on the forwarding chip, and the SRAM and DRAM

[0031] At the same time, it is used as the memory of the traffic statistics counter in the forwarding chip.

[0032] The above SRAM can use QDR SSRAM (Quaa Data Rate Synchronous SRAM, four times data rate synchronous SRAM) or DDR SSRAM (Double Data Rate Synchronous SRAM, double data rate synchronous SRAM), where QDR SSRAM can be QDR2 / QDR3 SSRAM, and higher in the future The first generation of QDR SSRAM, DDR SSRAM can be DDR2 / DDR3 SSRAM, and a higher generation of DDR SSRAM in the future. ...

Abstract

The embodiment of the invention provides a method and a device for managing statistical data of chip. The method mainly includes steps of obtaining statistical value of the statistical data of the chip, writing the statistical value in a static random memory (SRAM), moving the statistical value stored in the SRAM into a cache unit, and then, moving the statistical value stored in the cache unit into a dynamic random access memory (DRAM) when preset moving condition is satisfied. By simultaneously employing the SRAM and the DRAM to store the statistical data of the chip, the invention can effectively reduce storage cost of peripheral flow statistical counter of the chip and use quantity of chip IO and the SRAM, and lower demand for DRAM access bandwidth.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a method and device for managing statistical data of a chip. Background technique [0002] When communication devices (such as Ethernet switches, routers, etc.) are applied to telecommunication networks, their traffic statistics function is a key operable and maintainable function. Therefore, the industry's specification requirements for traffic statistics of communication devices, such as the number of statistical counters and statistical performance, are becoming higher and higher, which leads to a continuous increase in the cost of implementing the traffic statistics function. [0003] In high-end communication equipment, since the traffic forwarding function is implemented by the chip, the traffic statistics function accompanying the traffic forwarding naturally also needs to be implemented by the chip. Because SRAM (Static Access Memory, Static Random Access M...
