Hello , first of all I need to make clear that although I understand , and have done projects modifying code that is already there (and created my own minions) , in the core of C and C++ I wouldn't consider to know those a bit, I have just a glimpse of what those languages are capable of. Let's suppose that you have a program that runs endless (almost) in C++ (lets call it A) and it can take take something for input and throw out a result. Differentiating input / outputs could be done through a port of this …

hello daniwebers... I am really stuck with this design of tables for calendar. Here is the thing...there are employees in a specific company. Each employee accepts customers of the company per day. The number of customers is limited by the doctor on a day by day basis. So for e.g. Emp 1 can say 0 customers on sunday, 10 customers everyday monday, 8 every wed.... Thats one. 2. For each day with customers>0, emp sets the hour he is avalialble...from 8am to 4pm and he intends to spend XX minutes with each customers. 3. And some days will not work …

Hi Guys, I am planning to create one application that has 3 different Layers (clients) and each Layer has a same copy of an application and multiple users. any suggestions? Example : Application Client1 (has copy1 of application)(has n users) client2 (has copy2 of application)(has n users) client3 (has copy3 of application)(has n users) I am planning to user SQL Server as database.

I have some questions regarding design pattern (DP) usage, in particular for Java developers. i) Which DPs have you used, as far as you can remember, and how often? ii) How much have they helped your development work? iii) If you work in a project group, are there group standards for architectural and design pattern usage? iv) How can patterns be used more beneficially? v) Did you (or your group) get design pattern training? Thanks for your contribution.

And the microprocessor? I want to know exactly how this all works. Wikipedia claims that an instruction set architecture determines the data, registers, addressing modes, memory, etc. It also claims that it dictates the opcodes on a microprocessor. Wikipedia says "Microarchitecture" is the way a given ISA is implemented on the chip itself. But if the ISA dictates the specifications of the chip implemented on the micro side, what is the ISA? And how does it differ than the microarchitecture on the chip exactly? This is unclear to me. Like, let's say I want to develop for the chip in …

im trying to figure out why we are using binary computers insted of ternary. from what i can tell the only valid argument is the cost of storage. basicly for those of you who dont know that a ternary computer is, its a computer that uses three positions of the digital wave form as imputs so yo have +1 0 -1 interperated as 1 0 2 insted the the normal +1 -1 being interperated as 1 0. acording to my research there are existing storage mediums that are capable of storing 3 positions but they just cost more. i also …

I'm having doubts about a need to use a singleton pattern in a web service. I'm building a web service that is acting as a server side for multiple clients. I was thinking about making my business logic classes a singleton classes but i'm having doubts because of the following scenario: When the web service receives calls from multiple clients simultaneously to invoke the same method,i assume that they all have to wait in a queue because there is only one business logic instance. On the other hand, having the same scenario without using a singleton will cause multiple business …

ARE ALL x86 POCESSORS CISC

From what I understand, ALU is exclusively for mathematical operations. For simple tasks like reading a web page, saving a text file, copying data etc., are arithmetic operations used or can the processor do it without using that? I don't have much knowledge about computer architecture, but it seems to me that these jobs mainly deal with control instructions and no arithmetic is required, apart from maybe ASCII conversions.

I would like to know what kind of CPU architecture I should choose for creating my first operating system. I personally would like to give it a go with trying out a RISC type CPU, but if it's better to try it out on an x86 or some other type of CISC type architecture, that would be okay. I just want some opinions on what I should try for a first go. My needs are not specific as this is the first one I'll be doing. Thanks :3

Hi All I've been working on a program that automates a test sequence for testing a product before it is sent to the user. The program controls 12 test stations. There is an object that controls the interactions with each station (12 instances total). One of the challenges of the design was how to keep the state machines of each station synchronised. This has been achieved by passing a record from the creating object to each station instance. This record contains flags that describe the state of each object. I was wondering, is there a better way for multiple instances …

So, I'm studying Processor Design (very basic lol) but I need some input.. In a 1-Bus architecture for a CPU, doing an operation at the same time like: R[3] <- R[1] + R[2] : R[4] <- R[3] + R[1] + R[2]; where if R1 = 5; R2 = 6; R[3] = 5 (before first instruction); after the two instructions are finished, R[3] = 11; and R[4] = 16 can be accomplished easily; however, for a 2 bus architecture is this possible? I'm finding that it can't be, but I want some more input. Thanks for the help! Here's a 1-Bus: …

Hi, I want to develop a an application based on independent "CustomModule" that all derived from a base class "BaseModule" and that can send different kind of "CustomEvent" (derived from a "BaseModule" class) to each other. Each Module just knows that it is connected to others "BaseModule" (i.e. it does not know the specific type of "CustomModule" they are). So the problem is the following: How can I specialize the code of CustomModule depending on the CustomEvent type that it receives and in the same time keeping a generic interface communication between Modules ? A precision: this code have to …

I am asked to add a madd(multiply and add) instruction to the standard single cycle datapath. I am quite confused on how to achieve this... any idea? Below is the description.. Description: The 32-bit word value in GPR rs is multiplied by the 32-bit word value in GPR rt, treating both operands as signed values, to produce a 64-bit result. The product is added to the 64-bit concatenated values of HI and LO.. The most significant 32 bits of the result are written into HI and the least signficant 32 bits are written into LO. No arithmetic exception occurs under …
