help please

1, (4 points) Assume a color display using 16 bits for each of the primary colors (red, green, blue) per pixel and a frame size of 1920x1080. a) What is the minimum size in bytes of the frame buffer to store a frame? b) How long would it take, at a minimum, for the frame to be sent over a 50Mbps network? 2. (6 points) Consider three different processors P1, P2, and P3 executing the same instruction set. Pl has a 3GHz clock rate and a CPI of 1.5. P2 has a 2.5GHz clock rate and a CPI of 1.0, P3 has a 4GHz and a CPI of 2.5. a) Which processor has the highest performance expressed in instructions per second? b) If the processors each execute a program in 5 seconds, find the number of cycles and the number of instructions. We are trying to reduce the execution time by 20% but this leads to an increase of 15% in the CPI. What clock rate should we have to get this time reduction
