Q2. Consider the following RISC-V loop: (i) (ii) (iii) (iv) (iv) (v) (vi) (vii) LOOP: beq x6, addi x6, x6, -1 add x11, x11, x5 addi x5, x5, 2 slli x7, x5, 1 beq x0, x0, LOOP beq x11, x0, DONE 2 | Page Assume that the register x6 is initialized to the value 5, x5 and x7 to the value 0, and x11 to the last digit of your student ID. All these initializations are performed using RISC-V instructions. Fill out the table below. Final value of x5 at the end of execution Final value of x7 at the end of execution Total number of instructions executed DONE: add x12, x11, x19 microarchitecture x0, DONE Number of cycles needed to execute these instructions in a single cycle microarchitecture Number of cycles needed to execute these instructions in a multi-cycle

Thank you for the help!     This is a block diagram of a 4-bit analog to digital converter (A/D).  Assume the analog input ranges from 0 to 10.0 volts.  Fill in the conversion table for the A/D converter.  Note that most, but not all, consumer applications use 8-bit A/D and D/A conversions.

Draw the output waveform of the following Clipper’s circuits while the input is givenb below and biasing voltage (V=5v) is 5 v. Practical silicon diode is to be considered for  analysis to draw output waveform.

Using an ideal diode, design a clamper circuit that result in the desired output waveform as shown in Figure Q7. Show overall analysis to justify the proposed design. 7. Vo Vi Designed Clamper Circuit - 3 V -20 - 43 V - Fiqure Q7 20
