Embodiment Construction
[0028] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other arbitrarily if there is no conflict.
[0029] Such as figure 1 As shown, an adaptive and dynamic bandwidth adjustment device includes: a storage scheduling module, a data processing module, and a write storage control module. In this example, a channel read request conversion module and a read storage control module are added.
[0030] The write storage control module is used to complete the data write request, data and address control. When the data to be written meets the requirements for writing to external memory, the write storage control module is used to send a write request, write address and data to be written to the stor...

The invention discloses a self-adaptive dynamic bandwidth adjusting device and a self-adaptive dynamic bandwidth adjusting method to overcome the defect that the existing bandwidth cannot be adjusted in real time according to the current network situation. The device comprises a read storage control module and a channel read request converting module, wherein the channel read request converting module is used for respectively accumulating data bit width requested by the read request from each channel; if the accumulated value of the data bit width requested by the read request from certain channel is more than the preset data bit width value, the channel read request converting module generates and buffers the read operation request of the channel; the data bit width value requested by the read operation request is equal to the accumulated value; the read storage control module is used for judging whether the channel meets the read operation requirement when detecting that at least one channel read operation request is stored in the channel read request converting module, and reading out the read operation request and sending the request to a storage scheduling module if the channel meets the read operation requirement. By virtue of the device and the method, the bandwidth can be adjusted in real time according to the actual interface bandwidth requirement, and the design requirement on the storage scheduling bandwidth can be effectively reduced.
Description
Technical field [0001] The invention relates to the technical field of data buffer control, in particular to a device and method for adaptively dynamically adjusting bandwidth. Background technique [0002] When accessing data to the memory, a storage scheduling method that reads and writes the memory in time-sharing according to weight can be used. A weight value corresponds to a fixed scheduling bandwidth. The scheduling bandwidth must meet the bandwidth requirements of read and write data processing. The data bit width of the memory and the clock frequency of the control memory determine the total bandwidth of the scheduling, and the bandwidth of the final read and write scheduling Determined by the corresponding weight value occupied by read and write. Therefore, when the data bit width of the memory is determined, the scheduling bandwidth of the read and write data must meet the bandwidth requirements of the read and write data processing, and an appropriate clock frequency...
