I really need some help on this!

Homework Statement Hello! I need to implement a "branch if greater than or equal" and a "set if less than" in my 16-bit ALU (MIPS architecture),but I'm having some difficulties with it. Homework Equations The "set if less than" I think,if one considers overflow,it could be...

Homework Statement Given z=f(x,y),where f(x,y) is - say- f(x,y)=x^2-2y+4 how would I go about finding the range of the function like it was done for f(x)=y,when f(x)=x^2-1 ,for example,we would put x^2-1=y and solve for x?

Do the values of k must be within the range of the function?

What I don't understand is,why do we use the k constant with value 4 specifically?Why couldn't we use other value? Also,in the second piece of the function why do we equal sqrt(32-x^2-y^2)=4?Does it have anything to do with the fact that 4 is the point where the function switches to the other...

Hello! Homework Statement Well,I'm having a problem drawing level curves for piecewise functions. The problem is, how do I know which value the constant k will hold? Homework Equations The functions is the following: f(x,y)=4 if x^2+y^2<=16 sqrt(32-x^2-y^2) if...

Homework Statement Hello! I need to implement a set greater than and a branch less or equal in my 16 bit ALU design(MIPS architecture),but I'm having many difficulties. Homework Equations The Attempt at a Solution I know that in a set greater than a>b equals a-b>0 ,but I...

Any help is really appreciated!

Hello! I'm having problems figuring out how to extend the datapath and the blocks used for ble and sgt instructions on MIPS32. After studying a bit I managed to code the instructions for ble and sgt respectively: slt $t0, $s2, $s1 beq $t0, $zero, less_equal...

Hello! I have a project in which I must simulate a blog application,with users' post mangament. These are the requirements: A blog has a title and a collection of posts.The posts have the following information: -author -data -title -text Each post has a code that is generated...

So,the KCl for the shorted voltage would be something like this: va/2.5 + (va-vb)/10=6 (va-vb)/10=vb/10 + vb/20 Am I right? Oh,and could the voltage in the 40 resistor in the open current source be calculated by 10 and 2.5 in series,in parallel with 40 volts,in series with 20...

But,doesn't the combination 20//40 also shares a node with 2.5ohm resistor besides the 10ohm?

Anyone can help me?
