Answer 1

G: No. of global registers.

 

L: No. of local registers in each window.

C: No. of registers common to two windows W: No. of windows.

Window size (S): No. of registers available for each window.

Window Size= S= L+2C+G

Register file (F): Total no. of registers needed in the processor.

Register File= F= (L+C)W+G

B should be answer.

Which topic is this ?  Didn't come across this.

Is designing risc in the syllabus?

---

RISC questions are frequently asked in some Test Series now a days , who knows when one will come in GATE

---

test series every year

---

w= l+2c+g

=10+12+10=32

but register file=w(l+c)+g

                       =32(10+6)+10=522

how 74?

yeah same thing ..did you figure it out !??

---

I got it now 

W means no of window not window size
