program in SAP-1 using the mnemonics that will display the result of 4+5-2. Use addresses AH‚ BH and FH for data. 3. Briefly describe instruction set. Also discuss the use of bi-directional registers 4. Briefly describe the functions of various registers in SAP-1 architecture 5. Suppose we want to transfer the data from memory to B register. We need a new instruction‚ say OMB (Out Memory data to B register). What are the complete SAP-1 microinstructions for this? Express your answer in hexadecimal

Exam 2 Objectives Chapters 8 & 9‚ class notes (ACT) and discussions 1. Describe typical problems people demonstrate when trying to solve problems Functional Fixedness: This term refers to the tendency to view problems only in their customary manner. Functional fixedness prevents people from fully seeing all of the different options that might be available to find a solution. Assumptions: When dealing with a problem‚ people often make assumptions about the constraints and obstacles

Introduction to 8085 programming model Introduction to 8085 instruction set All computers are based on the Turing Machine concept • In 1937‚ Alan Turing described this abstract idea of a computer • Turing Machines consist of: – A tape of infinite length with symbols printed in cells – A read-write head that can move along the tape to read and write symbols – A state from a finite set stored inside the machine – A finite set of instructions that translate the current state and the read symbol

system like input and output. The instruction set is very limited and is simple. The features in SAP-1 computer are W bus - A single 8 bit bus for address and data transfer. 16 Bytes memory (RAM) Registers are accumulator and B-register each of 8 bits. Program counter – initializes from 00H (0d) to FFH (15d) during program execution. Memory Address Register (MAR) to store memory addresses. Adder/ Subtracter for addition and subtraction instructions. A Control Unit A Simple Output

The lesson was based on how to teach addition and subtraction to first grader. In this paper I will be observing an elementary mathematic lesson based on a math standards. The standards The National Council of Teachers of Mathematic (NCTM) are to guide educators on how to teach math the correct way. In comparing

represented with 1 or 0. In this discussion‚ we will explore reasons for choosing the bit as the lowest level encoding. We will also discuss how it can be efficiently stored‚ transferred and executed. Finally‚ we will examine ways to optimize binary instructions. Computers are essentially electrical components. Electrical components can only hold two distinctive states. They are “On” and “Off”. In order to represent these states‚ the binary system was created. Capitalizing on the ground works of the
