We need to build a RAM that can store 128, 64‐bit words and has 1 write port and three read ports
- How many address bits does my RAM need for its write port?
- How many data bits does my RAM need for each read port?
你给翻译翻译，什么叫做store128 ,64-bit words?
- 可存储128个64位的数
知道这点后这题就简单了！
第一问：因为需要访问128个数，因为2∧7=128，所以需要7个地址位（其实就是七根地址线）
第二问: 因为需要访问64位的数据，所以就需要64个数据位，切~（就是这么简单，我居然没转过来，真想给自己两巴掌）
