Repeat Problem 6.2.46 if a 64-kbit ROM is to provide a 16-bit output word.

Problem 6.2.46

Show the schematic arrangement for:

(a) one dimensional addressing, and (b) two-dimensional addressing (see Problem 6.2.45), if a 32-kbit ROM is used to provide an 8-bit output word.

Problem 6.2.45

Suppose a ROM holds a total of 8192 bits.

(a) How many bits long would the individual addresses have to be?

(b) If the bits are organized into 8-bit memory words or bytes, how many words would there be, and how many bits long would the addresses have to be?

(d) If each location requires its own word line emanating from a decoder AND gate, how many gates would the decoder for 1K-byte ROM have to contain?

(e) Develop a two-dimensional addressing system using a 6-to-64 decoder, a 64-word×128- bit matrix, and 16-input multiplexers. How many gates would such a system require?
