Question 20 5 pts Suppose a computer has 32-bit instructions. The instruction set consists of 64 different operations. All instructions have an opcode and two address fields (allowing for two addresses). The first of these addresses must be a register direct address, and the second must be a memory address. Expanding opcodes are not used. The machine has 16 registers. What's the size of the largest memory space that can be addressed by this computer?Assume byte addressable memory.

I would like a step by step explanation as to how the 7-bit floating point representations from Format A were converted to Format B. Thanks. Consider the following two 7-bit floating point representations based on the IEEE floating point format. Neither has a sign bit - they can only represent non-negative numbers. i). Format A. There are k=3 exponent bits. The exponent bias is 3. There are n=4 fraction bits. ii). Format B. There are k=4 exponent bits. The exponent...

Given: The following questions deal with two unsigned 6-bit numbers shown below in the hex format. A= 0x08 B=0x15 Suppose that the multiplier shown below is used to calculate the product of A (Multiplicand) and B (Multiplier) (Assume both values are unsigned). Consider using the "Add-and-Right-Shift Multiplier" design to compute A*B. You may assume all registers are large enough to contain as many bits as are required. Sought: a) What are the value in for the Multiplicand, Multiplier and Product...

An IP address is a 32-bit number that uniquely identifies a host (computer or other device, such as a printer or router) on a TCP/IP network. IP addresses are normally expressed in dotted-decimal format, with four numbers separated by periods, such as 192.168.123.132. To understand how subnet masks are used to distinguish be- tween hosts, networks, and subnetworks, examine an IP address in binary notation. For example, the dotted-decimal IP address 192.168.123.132 is (in binary notation) the 32 bit num-...

1. Questions (a) Truncations chooses the closest machine number in the direction towards zero. This implies that for positive numbers the result is less or equal than the original mumber while for negative numbers the result of truncation is larger or equal than the original number. Round to nearest chooses the closest machine number. This minimizes the absolute error imtroduced by the rounding (b) 32-bit significant: es 21-32 2-31=0.466 x 10-9. (c) In divisions the maximum relative error is the...

For this assignment you will explore subnet addresses, host addresses and direct broadcast addresses. You will be provided an IP addresses and then asked to answer questions related to the IP. In this assignment, first we explain how to find the subnet address for each subnet, the range of host addresses, and the direct broadcast address. Then you will be asked to do a similar exercise by yourself. Assume that you have been assigned the 192.168.1.0/24 network. You need to...

You are given a homework processor (HPro) capable of addressing 32 8-bit (1 byte) wide registers. However, it has only 29 physical registers. Register RO, R1 and R31 are not physically implemented. Instead, every read from RO, R1 and R31 will return a constant zero (00000000), constant one (00000001) and all ones (11111111), respectively. Every write to RO, R1 and R31 will go to null (dummy write). Assume that all other registers have initially unknown (X) state (This in fact...
