Embodiment Construction

[0047] The present invention is a layout method of dynamically reconfigurable FPGA, constructs computing resources of FPGA dynamically reconfigurable system, and establishes a single hardware task T n In the FPGA online layout process, the FF Reshaped-Task-Model scheduling algorithm is used to deform the task model to complete the layout and improve the utilization of FPGA resources.

[0048] Include the following steps:

[0049] S1. Define the size of resources in the reconfigurable area;

[0050] see figure 1 , FPGA(W,H) represents the computing resource of the dynamic reconfigurable system, W represents the width of the reconfigurable resource, H represents the height of the reconfigurable resource, W×H represents the size of the reconfigurable resource, then:

[0051]

[0052] S2. Establish a Reshaped-Task-Model model based on a single hardware task

[0053] see figure 2 , a single hardware task uses T n =(a, e, d, w, h) means that a is the arrival time of the tas...

Abstract

The invention discloses a layout method of dynamic reconfigurable FPGA. The method comprises the steps that calculation resources of an FPGA dynamic reconfigurable system are constructed, a bit map method is adopted to conduct management of the FPGA calculation resources, a task model of a single hardware task Tn is established, and during the process of FPGA online layout, deformation is conducted on a task model by using an FF Reshaped-Task-Model scheduling model to complete layout. According to the method, a strategy of changeable task model is introduced in the process of FPGA online layout, under the situation that the first layout fails, the shape of an online task is changed, a layout algorithm is scheduled again, the flexibility of a task is increased due to the fact that the shapeof the task is changeable, the selectivity of the task when layout is performed is improved, so that the success rate of task layout is increased, and the utilization rate of the FPGA resources is increased.

Description

technical field [0001] The invention belongs to the technical field of reconfigurable computing, in particular to an online layout method of FPGA (Field-Programmable Gate Array) field programmable gate array. Background technique [0002] In the era of big data, the amount of data is growing exponentially, which requires faster and more complex processing of data.
