使用javascript模拟并行位全加法器

解析：

const A = [1, 0, 0, 1];
const B = [1, 1, 0, 1];
function plus (a, b) {
    let GList = [], PList = [], res = [];
    while(a.length) {
        let ai = a.pop()
        let bi = b.pop()
        let Gi = ai && bi;
        let Pi = ai ^ bi;
        let worker = new Worker('./worker.js')
        worker.postMessage({GList, PList})
        worker.onmessage = (event) => {
            let ci = event.data;
            let si = Pi ^ ci;
            res.unshift(si)
        }
        GList.unshift(Gi)
        PList.unshift(Pi)
    }
    let worker = new Worker('./worker.js')
    worker.postMessage({GList, PList})
    worker.onmessage = (event) => {
        res.unshift(event.data)
        console.log(res)
        return res;
    }
}
plus(A, B)






以上 main.js




self.addEventListener('message', function (e) {
    let GList = e.data.GListlet PList = e.data.PListlet ci = 0;
    while(GList.length) {
        let gi = GList.pop()
        let pi = PList.pop()
        ci = gi || pi && ci;
    }
    self.postMessage(ci)
    self.close()
}, false)




以上worker.js
