如何在iOS应用程序中显著降低能耗影响?

我正在开发一个具有Vision框架功能的ARKit应用程序(处理CoreML模型)。

loopCoreMLUpdate() 函数生成一个循环,该循环导致 超高能量冲击 (CPU=70%,GPU=66%)。

如何处理这项任务并将能源影响降低到较低水平 ?

这个循环问题的解决方法是什么,可以帮助我减少CPU/GPU工作负载 ?

这是我的密码:

import UIKit
import SpriteKit
import ARKit
import Vision

class ViewController: UIViewController, ARSKViewDelegate {

    @IBOutlet weak var sceneView: ARSKView!
    let dispatchQueueML = DispatchQueue(label: "AI")
    var visionRequests = [VNRequest]()

    // .........................................
    // .........................................

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        let configuration = AROrientationTrackingConfiguration()
        sceneView.session.run(configuration)

        loopCoreMLUpdate()
    }

    func loopCoreMLUpdate() {          
        dispatchQueueML.async {
            self.loopCoreMLUpdate()  // SELF-LOOP LEADS TO A VERY HIGH IMPACT
            self.updateCoreML()
        }
    }

    func updateCoreML() {
        let piBuffer: CVPixelBuffer? = (sceneView.session.currentFrame?.capturedImage)
        if piBuffer == nil { return }
        let ciImage = CIImage(cvPixelBuffer: piBuffer!)
        let imageRequestHandler = VNImageRequestHandler(ciImage: ciImage, options: [:])

        do {
            try imageRequestHandler.perform(self.visionRequests)
        } catch {
            print(error)
        }
    }
    // .........................................
    // .........................................
