기출 퀴즈

 

    What were three important changes from the 801 to the improved 801? For each of these three changes, list the key advantages and disadvantages (if any), and state whether the change makes the newer processor more RISC-like or CISC-like than its predecessor.

 

    Software technology had a large impact on the 801 projects. Describe both the role of a software simulation of the 801 and the 801 compiler in the 801 project.

 

801 Architecture

 

     The 801 was an experimental mini-computer designed by IBM. The resulting architecture was used in various roles in IBM into the 1980s.

 

Branch 란

 

A branch in a computer program is an instruction that tells a computer to begin executing different instructions rather than simply executing the instructions in order. In high-level languages, these are typically referred to as flow control procedures and are built into the language. In assembly programming, branch instructions are built into a CPU.

Microcode 란

 

Microcode is a computer hardware technique that interposes a layer of organization between the CPU hardware and the programmer-visible instruction set architecture of the computer

 

Bootstrapping 이란

 

Bootstrap is the program that initializes the operating system (OS) during startup.
