Show a 64 bit instruction format that allows for 64 instructions and the rest of the bits allocated for addressing.  How many bits are allocated and how much memory can you address?

In this case, every instruction gets its own data in a way that is completely separate from how the data of other instructions is obtained. We utilize: A Multiple Data/Instruction B Multiple Data/Instruction C Singular Data Single Inst D Singe Inst Multiple

Given a computer with 300 memory locations, each 18-bit assessable, how many bits of addressing are needed?  Given a computer with 10-bit addressability and 5 bits for the address, what's the maximum number of memory this computer can have in bits?

Explain the instruction pointer in a few words.

Let us assume that we would like to design an ISA R-format instruction format for a processor. The processor has 256 registers and 64 opcodes. The R-format has four fields, the opcode and three fields for the registers. Show the instruction format and the bit allocation for each field.
