a)What is the maximum memory address space that the processor canaccess directly if it is connected to a "16-bit memory"?
b)what is the maximum memory address space that the processor canaccess directly if it is connected to an "8-bit memory"?
c)what architectural features will allow this microprocessor toaccess a separate "I/O space"?
d)if an input and an output instruction can specify an 8-bit I/Oport number, how many 8-bit I/O ports can the microprocessorsupport?How many 16-bit I/O ports? Explain.1 answer

Anonymous askedConsider a sys...Can you please show me how to do problem 6 from chapter7.The question is as follows:Consider a system consisting of 4 resources of the same typebeing shared by 3 processes. Resources can be requested andreleased by processes only one at a time. Show that the system isdeadlock free.Thank you•1 answer
Sulman askedzeros in a wo...Question:
Using SPIM, write an efficient routine for determining the numberof trailing zeros in a word. It is possible, of course, tosimply shift right until a one occurs in the least significantdigit. But this is extremely inefficient. How can you determine thenumber of trailing zeros in a word without doing any looping?

The answer for it in the Answers section for OperatingSystems Concepts ed.7 is not correct. It merely tells thedefinition of each without any disadvantages and advantages. Thebook is aslo of no help.

Each slip contains the salepersonnumber, product number and the total dollar value of that productsold that day. The program will prompt error messageif user does not type 1-4 as saleperson and type 1-5 asproduct number. Write a program to calculate the total dollarvalue of 5 days and the total product sold by eachsaleperson. The tabular printout should include the cross totals tothe right of the total rows and to the bottom of the totalcolumns.Use a two-dimension array to solve this problem.1 answer
