RISC V EDITION EXAM SCRIPT FULL
QUESTIONS AND CORRECT ANSWERS
GRADED A+
●● state element
Answer: A memory element, such as a register or a memory.
●● clocking methodology
Answer: The approach used to determine when data are valid and stable
relative to the clock.
●● edge-triggered clocking
Answer: A clocking scheme in which all state changes occur on a clock
edge
●● control signal
Answer: A signal used for multiplexor selection or for directing the
operation of a functional unit; contrasts with a data signal, which
contains information that is operated on by a functional unit.
●● asserted
Answer: The signal is logically high or true.
, ●● deasserted
Answer: The signal is logically low or false.
●● datapath element
Answer: A unit used to operate on or hold data within a processor. In the
RISC-V implementation, the datapath elements include the instruction
and data memories, the register file, the ALU, and adders.
●● program counter (PC)
Answer: The register containing the address of the instruction in the
program being executed.
●● register file
Answer: A state element that consists of a set of registers that can be
read and written by supplying a register number to be accessed.
●● sign-extend
Answer: To increase the size of a data item by replicating the high-order
sign bit of the original data item in the high- order bits of the larger,
destination data item.
●● branch target address
