Assume a 64Kx8 Memory is designed using 16Kx1 RAM chips. How many address lines must be decoded externally to each 16K RAM chip?

Solutions

Expert Solution

So a total of 32 (16K*1 RAM ) chips are needed to build a 64K*8 RAM

since 64K*1 RAM uses 4 (16k×1RAM )

And we use 8 (64kx1RAM ) blocks to build 64Kx8 RAM chip i.e (8*4=32)

For the following, give constructions using a straightedge and a compass with memory. You must prove that your construction works. We say that a positive real number a is constructible if whenever we are given a line segment of length c , we can construct a line segment of length ac . Suppose that a and b are constructible real numbers. Show that ab is also constructible.

Example: A 3-address computer has 40 instructions, 16 Registers, and 256KB memory. Assume each instruction has three operands. Two registers and the third operand is a direct address location of a memory. Find minimum size of PC, MAR, MDR, IR. Solution: OPCODE R1, R2, address OPCODE is 6 bits since 2^6>40 Register field is 4 bits since 2^4 =16 Memory field is 18 bits since 2^18=256K Instruction length =6+4+4+18=32 bits MDR=32 bits IR=32 bits MAR=18 PC=18 Please explain
