3. (15 Pts.) In this problem you are given a microprocessor with 24-bit address bus and 8-bit data bus. a. What is the addressing space of this microprocessor? 113 16 MB b. how many bytes are contained in the sub-space starting at address C00 000h and ending at address DFF FFFH? Express your answer in KB and MB. DFFFEE CoO DOU - TFFFFF in ke 20 4SKe c. You would like to interface a single 4 MB memory IC to this microprocessor so that the last address of the IC is at FFE EFEh Assume the IC to have CS1 (active-low) and CS2 (active high) in addition to the OE and WE (both active-low). What is the starting address of this IC's space ? Draw your interface. No foldback it to occur. Show all details. Ic : start : ooo00 END: FFFFFF An MEMB MEMW A. ir d. Unfortunately you check your store and it has 1 MB memory ICs only Repeat your interface using multiple ICs instead. Indicate the starting and ending of each IC. Use the 3- to-8 decoder (LS 138) for a more efficient design Show your interface at the paper back
