  • Organization &amp; Architecture UNISA Studies &ndash; Chap 13

    - by MarkPearl
    Learning Outcomes Explain the advantages of using a large number of registers Discuss the way in which compilers optimize register usage Discuss the evolution of CISC machines Describe the characteristics of RISC architecture Discuss the RISC vs. CISC controversy Describe the way in which RISC and CISC design principles can be combined Instruction Execution Characteristics To understand the the line of reasoning of RISC advocates, we need a brief overview of instruction execution characteristics. These include… Operations Operands Procedure Calls These three sections can be studied in depth in the textbook at pages 503 - 505 A number of groups have come up with the conclusion that the attempt to make the instruction set architecture closer to HLLs (High Level Languages) is not the most effective design strategy. Rather HLL’s can be best supported by optimizing performance of the most time-consuming features of typical HLL programs. Generally 3 main characteristics came up to improve performance… Use a large number of registers or use a compiler to optimize register usage Careful attention needs to be paid to the design of instruction pipelines A simplified (reduced) instruction set is indicated The use of a large register optimization One of the most important design principles of RISC machines is the use of a large number of registers. The concept of register windows and the use of a large register file versus the use of cache memory are discussed. On the face of it, the use of a large set of registers should decrease the need to access memory. The design task is to organize the registers in such a fashion that this goal is realized. Read page 507 – 510 for a detailed explanation. Compiler-based register optimization   Reduced Instructions Set Architecture There are two advantages to smaller programs… Because the program takes up less memory, there is a savings in that resource (this was more compelling when memory was more expensive) Smaller programs should improve performance, and this will happen in two ways – fewer instructions means fewer instruction bytes to be fetched and in a paging environment smaller programs occupy fewer pages, reducing page faults. Certain characteristics are common to RISC processors… One instruction per cycle Register-to-register operations Simple addressing modes Simple instruction formats RISC vs. CISC After initial enthusiasm for RISC machines, there has been a growing realization that RISC designs may benefit from the inclusion of some CISC features CISC designs may benefit from the inclusion of some RISC features

  • Planning for Recovery

    Uncertainty sets the tone of business planning these days and past precedents, 'rules of thumb' and trading history provide little comfort when assessing future prospects. After 18 years of constant growth in GDP, planning is no longer about extrapolating past performance and adjusting for growth. It is now about constantly testing the temperature of the water, formulating scenarios, assessing risk and assigning probabilities. So how does one plan for recovery and improve forecast accuracy in such a volatile environment?

    I have a luks setup with encrypted partition. And I don't want everyone on my computer to see that I have such partition. Unfortunately it shows up in the nautilus "devices" panel as "Encrypted partition". Is there a way to prevent it from showing there?

  • What are some known approaches to collaborative schema design?

    - by Omega
    If a project has multiple developers, each with useful knowledge & experience that can aide in the design of a schema; what are some known processes to collaboratively plan that schema out? Are there any types of meetings that are useful for this purpose? This would be in contrast to circumstances where projects are started and models are developed unilaterally by coincidence rather than as part of a structured understanding of the domain.

  • How hard is to be the anonymous owner of a website?

    - by silla
    I'd like to create a website with a very radical political message. It won't be unethical (encouraging violence, etc) but I feel the points I plan to list in it will definitely make me a lot of enemies. How hard would it be to protect my identity from anyone finding out who I am? I know domains always have a $10/year option for privatizing your registration information but is there any other protection I should think about having? Thanks!

  • Is a startup revolving around a web app still viable?

    - by NRUTA
    I have an idea for a startup that revolves around a web app. I plan to incorporate a mobile app in the future but, unlike something like instagram, users will be more likely to access with a desktop computer. I am learning Ruby On Rails currently but wonder if, starting in the 4th quarter of 2012, I am focusing on a technology (web development) that is becoming obsolete. Should I dump the idea for something that revolves around mobile technologies and spend my time learning something like iOS development instead?

  • Which one to select for my future career; Java, C#, Azure or Apex?

    - by user636195
    Hi folks, This time, I am going to studying Masters in Computer Science in U.S.A after a week. I have been doing my B.Sc for the past three years and after my freshman year I started working on projects (in C# and very rarely in Java) for the past two years.(i.e while I was a second and third year student). Now I am in a college where all of the programming courses are going to be taken in Java only (using Eclipse) and I am going to stay in this college for 8 months on campus and then fully employed for two years in other companies as a CPT. I really love to work on Microsoft products because, for me, they are simple and easy to use and understand. My future plan is to work in Cloud computing and be a Cloud based business owner in the near future. Since the college is going to teach us and let us do every project in Java, I was confused which programming language to use that will help me and enhance me in my career, and of course I wanted to select the one I liked to do everytime. I also heard a lot about Azure (Microsoft’s ) and Apex (Salesforce.com’s cloud computing programming language). Would you please give me your advice and recommendation based on my situation? Should I have to study only Java, or should I have to study C# or Azure beside Java on my own? The reason I asked this is because, since I have no clue how Azure works and how long it will take me to know the language, I am really confused which one to select (Java Vs C# and Azure Vs Apex or if there is any popular and mostly used Cloud Computing langauge). Do you think I can get a job in cloud computing if I study Azure or Apex by my own without experience? There is also one issue I want to consider which is a short term issue is. i.e Salary. Since I have to pay my student loan, I also need to get a good job which will let me pay my loan within two years. But, as I said, my long term plan is, get experience in Cloud Computing (from programming to administrative part,i.e every area of cloud computing) and then have my own business may be within 5-10 years. What do you think? Thank you for your time.

  • Is possible to create an intranet site in Ruby on Rails? [closed]

    - by Akromyk
    I'm just coming out of a .Net course and I'm wondering whether it is possible to create an intranet site using Ruby on Rails, and if so, would it even be a good idea. I plan on creating a web site for a vendor that hopes to open up a physical location and it would be beneficial for us to go with a technology that could tie their web front into their intranet for helping them manage orders and logins, but at the same time still have a low cost.

  • Managing Printers with Group Policy, PowerShell, and Print Management

    Just because it is possible to do many configuration jobs 'click by bleeding click', doesn't mean that it is a good idea. It is better to step back, plan, and use the advanced resources provided for managing large network. Printer configuration is the perfect illustration of this, and Joseph demonstrates how the use of Group Policy, PowerShell, and Print Management can turn a time-consuming chore into a pleasure.

  • In a pinch, is it worthwhile to run a bootable USB drive for my primary PC for an extended period?

    My hard drive has crashed, and I won't be able to buy a new one for a month or two. I've got a 16GB USB 3.0 flash drive that I'd like to have running a persistent ubuntu or ubuntu gnome distro. While it's not the best solution, is it a solution, or is it just a good way to wear out a flash drive? I plan on mostly storing things in Google Drive, so other than wearing out the flash drive, are there any risks involved?
