WebA digital computer has a memory unit with 24 bits per word. The instruction set consists of 150 different operations. All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word of memory. How many bits are needed for the opcode? 8

WebAssuming that your machine is byte addressable (1 word = 1 byte), Let us solve the problem step by step. 1. Physical address = 36 bits. Since 32 bytes/line and size of cache line = size of main memory block, this means block offset = 5 bits. Hence remaining 31 bits is block number ( = tag + index). WebJan 21, 2015 · Here’s the quick tour: A bit is a single binary digit, 0 or 1. A byte is 8 bits side by side. A word is 2 bytes side by side. A double word is 2 words side by side. A quad word is 2 double words side by side. And this is from the book Principles of Computer Organization and Assembly Language: Using the Java Virtual Machine, Patrick Juola:

第一句就是计算wordIndex，通过wordIndex函数获取值。代码如下： 这里ADDRESS_BITS_PER_WORD的值是6，那么最先想到的问题就是：为什么是6呢？而不是其他值呢？ 答案其实很简单，还记得在最开始提到的：BitSet里使用一个Long数组里的每一位来存放当前Index是否有数存在。 因为在Java里Long类型 … See more 从上面已经知道在BitSet里是通过一个Long数组（words）来存放数据的，这里的expandTo方法就是用来判断words数组的长度是否大于当前所 … See more 这一行代码可以说是BitSet的精髓了，先不说什么意思，我们先看看下面代码的输出： 输出是： 这个输出看出规律没有？就是2的次幂，但是还是不太好理解，我们用下面的输出，效果会更好： 输出是： 从而发现，上面所有的输出 … See more
