中興和交大都出了這一題, 但我還是看不懂, 請問有人會這題嗎><?
An imaginary computer has 1024 words in memory,
four data registers (R0, R1, R2, R3),
and 16 different instructions (like add, subtract...).
(a) What is the minimun size of an instrction in bits
if a typical instruction uses the following format:
add 500 R2. (500 denotes the memoty address bus)
(b) If the computer uses the same size of word for data
and instructions, what is the size of each data register?
(c) What is the minimum size of the address bus?
(d) What is the minimun size of the control bus?

1F：推 carlos77373:(a)最短指令共 10+2+4 = 16 bits 03/20 19:51
2F：→ carlos77373:(b) 16 bits (c) 10 bit (d) 4 bit 應該是這樣 .. =.= 03/20 19:52
