Q2. (a) Figure 2 shows the pinout diagram (and their functional description) of the 2114 Static RAM memory IC. Using a neat sketch show how such IC may be interfaced with an M68000 microprocessor to realise a system that needs 1K x 16 bits of RAM. [Note: 2114 is a 4-bit memory IC. You will need multiple ICs to make up the 16-bit address bus of M68000 processor.] Ao-Ag Pin Names Address Inputs A6 1 A5 2 A4 3 A3 4 AO 5 A1 6 A2 7 CS 8 GND 9 +23456700 18 Vcc WE Write Enable 17 A7 CS Chip Select 16 A8 1/01-1/04 Data Input/Output 15 A9 Vcc Power (+5V) GND Ground 14 I/O 1 13 I/O 2 Truth Table 12 1/03 CS WE Comments 11 1/04 Н Chip Deselected L L Write 10 WE L H Read Figure 2 (b) Design an address decoder circuit to realise the following memory map (shown below in hexadecimal notation). The unused address range should generate an active low signal to be connected to the BERR* input of the M68000 microprocessor. Use the partial address decoding technique for your design.

Draw the figure for memory segments with 8086 microprocessor software model. Explain the logical address structure used for each segment (Explain which registers are used in logical address presentation of each segment; segment address : offset address). Give an example solution to find the physical address in a segment from the logical address for 8086 microprocessor.
