目标
接上一节，通过基础的逻辑门实现 Not16、And16、Or16、Mux16 四个基础门。
Not16
/*** 16-bit Not:* for i=0..15: out[i] = not in[i]*/
/** Sets out[x] = Not(in[x]) */
CHIP Not16 {IN in[16];OUT out[16];PARTS:// Put your code here:Not(in = in[0], out = out[0]);Not(in = in[1], out = out[1]);Not(in = in[2], out = out[2]);Not(in = in[3], out = out[3]);Not(in = in[4], out = out[4]);Not(in = in[5], out = out[5]);Not(in = in[6], out = out[6]);Not(in = in[7], out = out[7]);Not(in = in[8], out = out[8]);Not(in = in[9], out = out[9]);Not(in = in[10], out = out[10]);Not(in = in[11], out = out[11]);Not(in = in[12], out = out[12]);Not(in = in[13], out = out[13]);Not(in = in[14], out = out[14]);Not(in = in[15], out = out[15]);
}
And16
/*** 16-bit bitwise And:* for i = 0..15: out[i] = (a[i] and b[i])*/
/** Sets out[x] = And(a = [x], b = [x]) */
CHIP And16 {IN a[16], b[16];OUT out[16];PARTS:// Put your code here:And(a = a[0], b = b[0], out = out[0]);And(a = a[1], b = b[1], out = out[1]);And(a = a[2], b = b[2], out = out[2]);And(a = a[3], b = b[3], out = out[3]);And(a = a[4], b = b[4], out = out[4]);And(a = a[5], b = b[5], out = out[5]);And(a = a[6], b = b[6], out = out[6]);And(a = a[7], b = b[7], out = out[7]);And(a = a[8], b = b[8], out = out[8]);And(a = a[9], b = b[9], out = out[9]);And(a = a[10], b = b[10], out = out[10]);And(a = a[11], b = b[11], out = out[11]);And(a = a[12], b = b[12], out = out[12]);And(a = a[13], b = b[13], out = out[13]);And(a = a[14], b = b[14], out = out[14]);And(a = a[15], b = b[15], out = out[15]);
}
Or16
/*** 16-bit bitwise Or:* for i = 0..15 out[i] = (a[i] or b[i])*/
/** Sets out[x] = Or(a = [x], b = [x]) */
CHIP Or16 {IN a[16], b[16];OUT out[16];PARTS:// Put your code here:Or(a = a[0], b = b[0], out = out[0]);Or(a = a[1], b = b[1], out = out[1]);Or(a = a[2], b = b[2], out = out[2]);Or(a = a[3], b = b[3], out = out[3]);Or(a = a[4], b = b[4], out = out[4]);Or(a = a[5], b = b[5], out = out[5]);Or(a = a[6], b = b[6], out = out[6]);Or(a = a[7], b = b[7], out = out[7]);Or(a = a[8], b = b[8], out = out[8]);Or(a = a[9], b = b[9], out = out[9]);Or(a = a[10], b = b[10], out = out[10]);Or(a = a[11], b = b[11], out = out[11]);Or(a = a[12], b = b[12], out = out[12]);Or(a = a[13], b = b[13], out = out[13]);Or(a = a[14], b = b[14], out = out[14]);Or(a = a[15], b = b[15], out = out[15]);
}
Mux16
/*** 16-bit multiplexor:* for i = 0..15 out[i] = a[i] if sel == 0* b[i] if sel == 1*/
/** Sets out[x] = Mux(a = [x], b = [x], sel = sel) */
CHIP Mux16 {IN a[16], b[16], sel;OUT out[16];PARTS:// Put your code here:Mux(a = a[0], b = b[0], sel = sel, out = out[0]);Mux(a = a[1], b = b[1], sel = sel, out = out[1]);Mux(a = a[2], b = b[2], sel = sel, out = out[2]);Mux(a = a[3], b = b[3], sel = sel, out = out[3]);Mux(a = a[4], b = b[4], sel = sel, out = out[4]);Mux(a = a[5], b = b[5], sel = sel, out = out[5]);Mux(a = a[6], b = b[6], sel = sel, out = out[6]);Mux(a = a[7], b = b[7], sel = sel, out = out[7]);Mux(a = a[8], b = b[8], sel = sel, out = out[8]);Mux(a = a[9], b = b[9], sel = sel, out = out[9]);Mux(a = a[10], b = b[10], sel = sel, out = out[10]);Mux(a = a[11], b = b[11], sel = sel, out = out[11]);Mux(a = a[12], b = b[12], sel = sel, out = out[12]);Mux(a = a[13], b = b[13], sel = sel, out = out[13]);Mux(a = a[14], b = b[14], sel = sel, out = out[14]);Mux(a = a[15], b = b[15], sel = sel, out = out[15]);
}
总结
使用基础的逻辑门，实现了多位逻辑门。
