q2mp plz provide answer for this question

a. Explain the purpose of 8288 bus controller and in which mode it is used. Illustrate, using block diagram, major parts of 8288 controllers. b. Design and illustrate the fully-buffered and de-multiplexed 8086 Microprocessor. The pin layout of the 8086 microprocessor is given in Figure 1. To reduce cross connections of lines, you may consider pin layout of 8086 microprocessor with relevant pins on one side. MED S
