Embodiment Construction
[0013] The present invention will be described in detail below according to the accompanying drawings.
[0014] refer to figure 1 , the general-purpose computing-oriented reconfigurable computing array of the present invention is composed of a reconfigurable computing unit and its adjacent reconfigurable computing units in the four directions of east, west, north and south respectively connected by two input data paths and two output data paths made.
[0015] The structure of each reconfigurable computing unit in the computing-oriented general-purpose reconfigurable computing array is as follows: figure 2 As shown, it includes an input routing module 1, an operation module 2, an output routing module 3, and a configuration module 4. The configuration module 4 is used to store unit configuration information and calculation constants, and is connected to all modules in the unit. Here, the configuration module 4 may be constituted by a register file file based on a dual-port ...

The disclosed array is composed of reconfigurable computation unit and its adjacent reconfigurable units connected to each other through two routes of input data channel and output data channel in directions of east, south, west and north. Each reconfigurable computation unit includes configuration module, computation module, input route module and output route module. Each reconfigurable computation unit operates based on configured information. Selecting the input data at connection channel between adjacent units and constant, the input route module generates and outputs data to be calculated to computation module to carry out computation. Selecting the input data and the computed result, the output route module generates the output data at connection channel between adjacent units. Advantages are: both simple logic control function and common computation function in high frequency, lowered wiring resource for connecting adjacent units only so as to raise use ratio of unit.
Description
technical field [0001] The invention relates to a computing-oriented universal reconfigurable computing array, which is suitable for computing-intensive application fields. Background technique [0002] Reconfigurable computing arrays are generally divided into general-purpose and computing-oriented types according to their application fields. [0003] At present, the general-purpose reconfigurable computing array wastes a considerable effective area due to its excessively large wiring resources, and its logic-oriented unit computing function affects its performance in the field of computing applications; while computing-intensive applications The reconfigurable computing array in the field, its fixed computing width and limited computing functions lead to it can only show better performance in a very small exclusive field, without good flexibility. Contents of the invention [0004] The object of the present invention is to provide a general-purpose reconfigurable comput...
