1. (40 pts) Given the following sequence of C operations, write an assembly language program for each of the four ISA classes we discussed: accumulator, stack, memory- memory, and load-store. Assume that all operands are initially in memory, and that all results must eventually be stored to memory. (For Load-store you may assume that registers R1 through R16 exist). Optimize where applicable. + ANA D = B + C; z = J - I; F = Z + G; B = F - A; Y = Z + B
