7. 15 You have been asked to design a small computing system with a customized 8 bit ISA that can execute the following types of program. You can assume that the variables are already loaded into some registers. You should consider using only the instructions covered in the lecture. Partial marks are allocated for optimized design (less no of instructions, registers) for (i 0 i 8, i++){ Result Result + Sum * 4 } Answer the following designing questions for the most optimized solution 1) How many formats would you choose? Why? 2) Draw the formats along with field name and number of bits in each field. 3) Draw a register table. (with register name, values and behavior) 4) Draw a table with list of instructions, instruction type, their opcode, functionality (if any) etc. 5) Translate the above code in assembly based on the answers 1-4
