2) You are to create a Stack ISA for variable size encoding. The ISA you create will have 8-bit, 16-bit, 32-bit unsigned and signed number. In addition you have 32-bit floating point numbers. You want to be able to pop constants of each data type. The memory address for push and pop variables are 24-bits. Opcode is 6-bits. Write out the fields of the encoding with the number of bits.

3) You are to create a stack ISA for fixed size encoding at 24-bits. You are only creating an ISA for 16-bits sign numbers with 16-bits of memory address. Write out the fields of the encoding with the number of bits. Tell the number of instructions your ISA can support.

4) Write out the fix-size instruction encoding for the accumulator ISA. Constants are 16-bit and Addresses are 20-bits. Math instructions, load and store instructions
