Ok thanks, so if the processor wants to access memory, it sends the virtual address to the mmu and the cache which then works out if it resides in cache (it always resides in ram also)? And if it resides in cache does it then go to the cache using a physical address (set no. , tag and offset) or...

Trouble understanding "Virtual cache" Hi, I'm having trouble understanding what virtual cache actually means. I understand that to get a cache hit (physical cache) you index to the cache set and compare all the tags in that set with the tag in the cache address you are looking for. I...

Solving differential with a step impulse. Hi, I have problem I know I should be able to do but I've been stuck on it for a while. Just looking to be pointed in the right direction. (dq^2/d^2t) + 2*ζ*ω*dq/dt + (ω^2)*q = u(t)/L Where u(t) is a step impulse, q is the charge through an...

Thanks for replying. The y coordinate is the force in this formula f=1/2l * √F/u is it not ? If so I want the force along the elastic which is this force divided by sinθ and sinθ is 1/L and the L's don't cancel so I still can't work it out ?

I would appreciate help on this problem. Homework Statement Homework Equations f = (1/2L)*sqrt(F/u) The Attempt at a Solution This is vibrating at its fundamental frequency so L = (wavelength/2). To find k I reckon I need to find the force on the band and this should equal -kx. But I...

Hi I am really stuck on this problem and would greatly appreciate some help. Homework Statement Homework Equations The Attempt at a Solution I would be able to solve this if the dam wasn't curved. I would just use integration to find the magnitude of the force f = pghA. I would express a...

Ok thanks for your help.

Thanks for replying. Are you sure it would be very strange if the list of answers are wrong as it was a previous exam paper. I agree by the looks of things the answer is c but was my method definitely right ?

Hi I would greatly appreciate help on this problem. Homework Statement Ok so here is the problem Homework Equations The Attempt at a Solution I first tried to work out the moments for the block on the ground with no angle to the ground. moments about a = .45(35000*g) -...

What is the differential equation that relates i(t) to v(t) ?

Thanks for the reply. I'm pretty sure we can use the differential equations. What KCL equation there are no nodes they are connected in series ? i1 = 12 ?? All I've got so far is that the moment the switch is closed i = E/R and the voltage across the capacitor = E - Vr which equals 0 as...

Hi I would appreciate some help on this question please. Derive the basic equation for the voltage across a capacitor as a function of time for a circuit that includes a resistor and capacitor connected in sereis to a battery through a switch. I know the formulas but haven't the slightest...
