A computer has a memory unit with 32 bits per word and has 16 general-purpose registers. The instruction set consists of 135 different operations. Some instructions have an opcode part, an address part, and a register part. Other instructions have an opcode part, and two address parts. Each instruction is stored in one word of memory. Explain how to determine opcode number of bits and explain how many bits are needed to specify a memory address

Write a program that performs a simple n-body simulation, called "jumping leprechauns." this simulation involves n leprechauns, numberd 1 to n. it maintains a gold value g_i for each leprechaun i, which begins with each leprechaun starting out with a million dollars worth of gold, that is, g_i = 1000000 for each i = 1,. in addition, the simulation also maintains, for each leprachaun,i, a place on the horizon, which is represented as a double-precision floating point number, x_i. in each iteration of the simulation, the simulation processes the leprachauns in order. processing a leprachaun i during its iteration begins by computing a new place on the horizon for i, which is determined by the assignment:
