摘要: 針對(duì)6G時(shí)代多樣的邊緣計(jì)算要求,,基于FPGA上的可重構(gòu)技術(shù)可以實(shí)現(xiàn)更低的時(shí)延同時(shí)提供多樣性的服務(wù),。基于局部動(dòng)態(tài)重配置的思路,,使用ICAP接口對(duì)FPGA資源進(jìn)行重新配置,,從而實(shí)現(xiàn)FPGA邏輯上的局部動(dòng)態(tài)可重構(gòu)方案。借鑒操作系統(tǒng)中軟件進(jìn)程管理的思想,,基于Linux操作系統(tǒng)中引入硬件進(jìn)程的概念,,這樣可以將一整塊FPGA資源劃分為多個(gè)小的FPGA資源塊,每一個(gè)小的可重構(gòu)的FPGA資源塊都可以抽象成為一個(gè)硬件進(jìn)程,,硬件進(jìn)程實(shí)際并不運(yùn)行在CPU上而是運(yùn)行在FPGA邏輯資源區(qū)域中,,在操作系統(tǒng)上只是硬件進(jìn)程的軟件語(yǔ)言描述。由此,,設(shè)計(jì)出CPU加FPGA的硬件方案來(lái)實(shí)現(xiàn)局部可重構(gòu)系統(tǒng),,并在Xilinx公司Zynq系列芯片上進(jìn)行了驗(yàn)證,將FPGA硬件資源進(jìn)行進(jìn)程式調(diào)度以及資源分配,,大大提高了FPGA硬件資源的利用率以及靈活性,。

Abstract: In view of the diverse edge computing requirements of the 6G era, reconfigurable technology based on FPGAs can achieve lower latency and provide diversified services. Based on the idea of local dynamic reconfiguration, the ICAP interface is used to reconfigure FPGA resources, so as to realize the local dynamic reconfigurable scheme on the FPGA logic. Drawing on the idea of software process management in the operating system, based on the concept of introducing hardware processes in the Linux operating system, it is possible to divide a whole block of FPGA resources into multiple small FPGA resource blocks, each small reconfigurable FPGA resource block can be abstracted into a hardware process, the hardware process is actually not running on the CPU but running in the FPGA logical resource area, and is only a software language description of the hardware process on the operating system. As a result, the hardware scheme of CPU plus FPGA is designed to achieve partial reconfigurable system, and verified on Xilinx Zynq series chips, and the FPGA hardware resources are scheduled and allocated in a process manner, which greatly improves the utilization and flexibility of FPGA hardware resources.
