Problems solved by technology

[0006] The technical problem to be solved by the present invention is: in modern electronic and communication equipment, the intensity of data processing increases very rapidly. For this high-speed data stream, it is often necessary to extract data with various characteristics and perform accurate statistics respectively. The higher the speed of the code stream, the more difficult it is to perform accurate statistics on the various data characteristics compounded in the high-speed code stream. The present invention explores a method that can realize fast 1 statistics based on this

Embodiment Construction

[0036] Please refer to the attached Figure 4 , 5 , 6, 7, and 8 show that the input signal of the present invention is a data stream (Data) 1 with address and composite multi-characteristics, and a data start signal (Sod) 2, which is connected to the data stream (Data) 1 The first data alignment, active high, the end of data signal (Eod) 3, the signal is aligned with the last data of the data stream (Data) 1, active high, and the data synchronization clock (Dclk) 4, its The implementation steps of the statistical bus are:

[0037] a), the statistical bus receives the input data coming in from the entrance, and under the synchronous control of the input data synchronous clock (Dclk) 4, check whether the data start signal (Sod) 2 is active at a high level;

[0038] b), when the data start signal (Sod) 2 is active at high level, it means that the data stream (Data) 1 data header of a complete data packet is found, then start the statistical processing unit module to extract the...

Abstract

A realization method for a high speed stream multikind of data calculation bus used in data process in test instrument or electronic communication equipments is that the said input signal is a data stream, data start signal, data finished signal and data synchronous clock, the calculation bus receives input data from the inlet, when the data start signal high level is effective, the starting calculation process unit module extracts address (or address identification) and property data from the data stream then to transfer the address to CAM for matching examine, if there is the matching and finding out the related ID to be sent for calculation. Advantage: it can be used in any electronic communication equipments needing calculation function.

Description

Technical field [0001] The invention relates to the field of electronic products, in particular to a method for realizing a high-speed code stream multi-type data statistics bus used for data processing in communication equipment or electronic products. Background technique [0002] The statistical functions of electronic products all have data processing units, statistical processing units and statistical units, such as figure 1 shown; any data that requires statistics can be converted (or not converted) to figure 2 For the bus type shown on the input side, set the timing of the input side as image 3 As shown, the existing data statistics implementation method is: extract the address and characteristic information from the input data, each characteristic leads to a signal, the signal is a pulse signal, and every time a pulse is generated, the characteristic is counted in the statistical unit Once, the signal waveform is as Figure 4 shown. There are disadvantages as f...
