In 16 words or less give definitions of the following debugging terms Instrument Intrusiveness Black-box White-box Minimally intrusive Stabilization There is a microcomputer embedded in a vending machine. List three operations the software must perform. What is the difference between a microcomputer and a microcontroller? Consider a system with four modules named A, B, C, and D. Draw the call graph if A, B, C calls A and D, and B calls C. Why can\'t the four individual modules in this system tested one at a time? List 3 factors that we can use to evaluate the \"goodness\" of a program. Draw a data flow graph of the thermostat algorithm developed in Exercise 1.27. Draw a data flow graph of the cruise control algorithm developed in Exercise 1.28. Draw a data flow graph of the incremental controller developed in Exercise 1.142. Draw a data flow graph of the stepper motor controller developed in Exercise Consider an MP3 player, which has a memory storage device, an MP3 decoder compressed data into raw form), buttons, an LCD a USB link to a PC, dual DACs output, and stereo headphones. Draw a possible data flow graph for system.

Solution

embedded:it is a computer system through a commited function in a huge electrical system ,also in real time computing conditions.now-a-days the embeddewd systema aredepending on the micro controllers.

device driver:In computier it is a computer programm which contols a specific kind of device which was joined to a computer.It communicates through the device via computer bus.

Top_Down: it ia a method that summary of a system is layed describing ,but not troop.it i9s additionally called as stepwise design.blac boxes are used which makes easy to manipulate.

call graph: it is additionally called as control flow graph that shows calling realationships among the subroutines in a computer.

control flow graph:it displays the data dependencies among many functions.its main aim is to utilize the hardware effectively.

sucessive refinement: it is an algorithm to elegant gradation in case of image processing.image processing permits the user .

Dynamic efficiency: it is a place where ,which was unable to generate single generation preferable off without producing any further generation skillfully off.

Real Time: it is a word utilized to tell a number of discrete computer attributes.for example a real time programm is able to displa the objects moving on the screen with similar speed which are able to move really.
