Computer architecture appendix B solutions ASAP?
i need solutions of problem B.1 and B.2 of book computer architecture by john hennessy and patterson 5th edition the B.1 question is L1 cache ,the latencies (in CPU cycles) of different kinds of access are follows: cache hit , 1 cycle ;cache miss,105 cycle; main memory access with cache disable ,100 cycles a.) when you run a program with an overall miss rate of 5% what will the avg. memory access ? b.) you use an array of size 256MB (fits in main memory) .Access to random elements of array are cont. made if your data cache is 64KB what will be avg. memory access time be..?? c.) if u compare result of part (b) with main memory access time when cache is disabled ,what do you conclude about role of principle of locality in justifying the use of cache memory..??? d.) you observed that a cache hit produces a gain of 99 cycles,but it produces a loss of 5 cycle in case of miss , we can express this two quantities as G (gain)and L (loss), identify highest miss rate after which cache use would be disadvantageous. Question B.2 is we assume we have 512-byte cache with 64-byte blocks . we will also assume that the main memory is 2KB large ,we can regard the memory as an array of 64-byte blocks :M0, M1,M3....M31.and fig B.30 sketches the mem blocks that can reside in different cache blocks if cache is fully associative a.) show the contents of table if cache is organised as a direct maped cache please refer book for figure b.30 b.)repeat part (a) with cache organised as 4 way set associative
Need Help with my Computer Science homework ASAP?
I have a few problems I need help with... 1. Clunker Motors Inc. is recalling all vehicles from model years 1995-1998 and 2004-2006. A bool variable named recalled has been declared. Given a variable modelYear write a statement that assigns true to norecall if the value of modelYear does NOT within the two recall ranges (2001-2006) and assigns false otherwise. Do not use an if statement in this exercise! I wrote this down: if(modelYear < 2001 || modelYear > 2006 ) norecall = 1; else norecall = 0; and it says an error message... ⇒ The value of norecall is incorrect. 2. In mathematics, the Nth harmonic number is defined to be 1 + 1/2 + 1/3 + 1/4 + ... + 1/N. So, the first harmonic number is 1, the second is 1.5, the third is 1.83333... and so on. Write an expression whose value is the 8th harmonic number. I dont know how to start this one all i know is that the myprogramming lab provided all this.... #include
Should I major in Architecture (as in building buildings) to pursue a UX career? Or switch ASAP?
So you've got a lot going on in your question (and yes, I agree this question is applicable to anyone considering switching majors). You say you understand that architecture is good preparation for a UX role, but have concerns that you aren't able to get graphic design, psych, cognitive science or product design courses, which seems to be your first choice(s) to round out your skills. You're also committed to doing personal projects and building a portfolio, regardless of your major, but the CS major would allow you to build your portfolio (an observation: you're really focused on that portfolio!). So... here are some questions:1. How does changing your major to CS address your concerns about the skills you're lacking?2. How likely is it that the websites, apps, software etc. that you'd be doing in the CS program would contribute to a better portfolio than the projects you'd do in the architecture program?3. What are the benefits of staying with your architecture program? What are the costs? How could an architecture background be used to differentiate you in UX?4. How much are you enjoying architecture? How much would you enjoy coding and learning CS content?5. What are some other ways of addressing your skill gaps (beyond changing your major)?Your answers to these questions can guide your decision. Here's also a couple related things that may help inform your decision:What is the quickest way to learn how to be a UI/UX designer in the UK? My background is Fashion and Administration-This is a career change. Should user interface designers be able to build what they design? And here's a personal philosophy that guides me at the moment: there are no mistakes. You seem clear on your goal, so your question really relates to the mechanics of how to get there. Both paths offer strengths and weaknesses and both can reasonably lead to your goal. So the question is ultimately this: which path will make the best use of your assets and promote the greatest satisfaction for you?Good luck!

What were the dominant features of the High Renaissance? help asap plz!!!?
The High Renaissance, in the history of art, denotes the culmination of the art of the Italian Renaissance between 1450 and 1527. Because Pope Julius II patronized many artists during this time, the movement was centered in Rome; it had previously been centered in Florence. The High Renaissance is generally held to have emerged in the late 1490s, when Leonardo da Vinci executed his Last Supper in Milan. The paintings in the Vatican by Michelangelo and Raphael represent the culmination of the style in painting. The style was introduced to architecture by Donato Bramante, who in 1502 built the Tempietto, with its majestic proportions signifying the full-scale revival of ancient Roman architecture. High Renaissance sculpture, as exemplified by Michelangelo's Pietà and David, is characterized by the ideal balance between statics and movement. The serene mood and luminous colours of Giorgione and young Titian exemplify the High Renaissance in Venice. The High Renaissance is widely viewed as the greatest explosion of creative genius in history. Even relatively minor painters active during the period, such as Fra Bartolomeo and Mariotto Albertinelli, produced works remarkable for their perfect harmony and control of the painterly mediums. The elongated proportions and exaggerated poses in the late works of Michelangelo, Andrea del Sarto and Correggio prefigure the nascent Mannerism, as the Late Renaissance is referred to in the history of art. Raphael's death in 1520 and the sack of Rome in 1527 spelled the end of the High Renaissance. High Renaissance sculpture was normally commissioned by the public and the state, this becoming more popular for sculpture is an expensive art form. Sculpture was often used to decorate or embellish architecture, normally within courtyards where others were able to study and admire the commissioned art work. Wealthy individuals like cardinals, rulers and bankers were the more likely private patrons along with very wealthy families; Pope Julius II also patronized many artists. During the High Renaissance there was the development of small scale statuettes for private patrons, the creation of busts and tombs also developing. The subject matter related to sculpture was mostly religious but also with a significant strand of classical individuals in the form of tomb sculpture and paintings.
What does the bus in the computer mean?
The bus lines are the communicating electronic lines that connect different parts of the CPU to various other parts. In addition, the bus lines also link the CPU to different parts on the system board of your computer. The data flows in the form of bits along the bus lines. The bus lines are like multilane pathway which means that the more bus lines are on the system the greater is the rate of transfer of data along the bus, which means that the computer can run efficiently and will perform the operations at a faster rate. There are several types of bus lines, some of which are as follows, Industry Standard Architecture, the bus line capacity is 16 bit. Though it is slow, it is still being used. Peripheral Component Interconnect has a speed of 64 bit which is being used widely in personal computers. Accelerated Graphics Port is mostly used for acceleration of graphics performance
