(5 pts) Which of the following are true about RISC-V instructions about the registers in the register file and instruction size?
(複選;至少一個正確選項,每個選項獨立計分。)
- (A)If the registers were halved, I-type instructions could have 2 more immediate bits.
- (B)If the registers were halved, there must be less I-type instructions.
- (C)If the registers were halved, shift amounts would change to 0-63.
- (D)Increasing the size of each bit field to support more registers potentially makes each instruction longer.
- (E)Increasing the number of registers must increase the code size of a RISC-V assembly program.
