1) Each of the following statements about Y86-64 are true. Which of them is an attribute that makes Y86-64 more RISC-like? Select all that apply. the OPq instructions operate only on registers there are few ways to specify instruction operands in Y86-64 • simpler instructions can take up less space than more complicated ones Y86-64 has only 18 instructions (counting conditional moves and conditional jumps each as one instruction) Y86-64 has instructions like pop which modify two registers, allowing for shorter programs

The I/O subsystem is a component of computer system design that uses buses to assist communication between the Central Processing Unit, Computer Memory/Storage, and Input and Output Devices (that is known as peripheral devices). The I/O subsystem include…
