Embodiment
The signal that device provided by the present invention can utilize the mode of real-time processing will have different pieces of information speed converts the signal with equivalent data rates to when output.The real-time processing of indication herein is the notion of TCM, one specified time interval is distinguished into several sections, carry out with the task component that an ad hoc fashion (equal proportion or inequality proportion) is suitably distributed in the device, make these task components be unlikely to idle too for a long time and elongate the time of handling, or miss received signal and lead to errors generation.
The embodiment of device provided by the present invention installs 1 and comprises a first task assembly 101, one second task component 103, one the 3rd task component 105 and one the 4th task component 107 as shown in Figure 1.The function declaration of each task component is as follows.
The 4th task component 107 is after receiving first data set 104 and second data set 106, in a special time, transmit first data set 104 forming one first output signal 108, and in same special time, transmit second data set 106 to form one second output signal 110.The 4th task component 107 is set at one the 4th priority.It should be noted that this special time is to decide according to the data rate that the system of installing 1 place can accept or expect.
Because the data slot length in first data set 104 and second data set 106 is just identical after first task assembly 101 is handled, send out via above-mentioned identical special time this moment again, can determine that first output signal 108 and second output signal 110 have identical data rate, reach the conversion of signals that to have different pieces of information speed by this and become to have the purpose of the signal of equivalent data rates.
In addition, the configuration of second task component 103 and the 3rd task component 105 (having more preferential processing sequence or long time of implementation than first task assembly 101) has allowed device more than 1 one-level (stage), and then when win data set 104 and second data set 106 are transmitted in device 1, can many chances utilize the configuration of priority " pressures " processing of expedited data, make data set can not be idle for too long because of the processing time of waiting next order four task component 107.Such configuration just can reach the purpose of real-time processing.
As shown in Figure 1, device 1 more comprises one first storage assembly 109, one second storage assembly 111, one the 3rd storage assembly 113 and one the 4th storage assembly 115.First storage assembly 109 is in order to receiving and to store first data set 104 from first task assembly 101, and the signal that waits second task component 103 transmits first data set 104 in the past.Second storage assembly 111 is in order to receiving and to store second data set 106 from first task assembly 101, and the signal that waits the 3rd task component 105 transmits second data set 106 in the past.The 3rd storage assembly 113 is in order to receiving and to store first data set 104 from second task component 103, and the signal that waits the 4th task component 107 transmits first data set 104 in the past.The 4th storage assembly 107 is in order to receiving and to store second data set 106 from the 3rd task component 105, and the signal that waits the 4th task component 107 transmits second data set 106 in the past; The priority of first priority, second priority, the 3rd priority and the 4th priority also can be complied with big or small adjustment of data volume that first storage assembly 109, one second storage assembly 111, one the 3rd storage assembly 113 and one the 4th storage assembly 115 are kept in, for example can reduce the order of first priority or improve second priority and the order of the 3rd priority during greater than a predetermined value when the stored data volume of first storage assembly 109 and one second storage assembly 111, vice versa; And reduce the order of second priority, the 3rd priority or improve the 4th priority greater than a predetermined value cocoa when the 3rd storage assembly 113 and the 4th storage assembly 115 stored data volumes, vice versa.
Said apparatus 1 is to be applied in the wireless communication system, is used for handling down the data rate of chain signal (downlink).And first task assembly 101, second task component 103, the 3rd task component 105 and the 4th task component 107 are task control square (task control block) in this embodiment.First storage assembly 109 and second storage assembly 111 are buffer in this embodiment, and the 3rd storage assembly 113 and the 4th storage assembly 115 are message queue (message queue) in this embodiment.
According to above-mentioned device 1, as shown in Figure 2, the present invention also provides a kind of real-time processing a plurality of wireless communication systems of chain signal down.This wireless communication system comprises one first device, 3,1 second device, 5 and 1 the 3rd device 7.First device 3 is in order to producing the first above-mentioned input signal 100 and second input signal 102, and utilizes wired mode (as the internet) to be sent to second device 5.Second device, 5 devices 1 that comprise in the earlier figures 1, its function and intraware repeat no more.The 3rd device 7 clients (as mobile phone) that are in the wireless communication system are to receive by second device, 5 first output signal that sends out and second output signals with communication.
Because second device, 5 devices 1 that comprise among Fig. 1, therefore wireless communication system provided by the present invention also can reach the conversion of signals that will have different pieces of information speed and becomes to have the signal of equivalent data rates and send out, and reduces the advantage of the time of deal with data speed simultaneously.
Above narration only is explanation spirit of the present invention, should be with this as restriction.Ripe this skill person can do suitable variation under the category that does not surmount claim and contained.
