1. 6502 assembly language references data in memory locations using an operand value containing the address (without the # character that indicates an immediate value). For example, the LDA $00 instruction loads the byte at memory address $00 into A. STA $01 stores the byte in A into address $01. Addresses can be any value in the range 0 to SFFFF, assuming memory exists at the address and the address is not already in use for some other purpose. Using your preferred 6502 emulator, write 6502 assembly code to store a 16-bit value into addresses $00-$01, store a second value into addresses $02-$03, then add the two values and store the result in $04-$05. Be sure to propagate any carry between the two bytes. Ignore any carry from the 16-bit result. Test with $0000+$0001, $00FF+$0001, and $1234+$5678.

3. virtual memory pages Consider the following code and READ the instructions carefully: static int a[3000]; void f() { int small[100]; int i; int j; for (i = 0; i < 100; i++) small[i] = 0; for (i = 0; i < 30; i++) { for (j = 0; j< 100; j++) smallj] += a[i*100+j]; } Assume pages are each 8K bytes. Also assume that the heap (where static data is stored) is more than 8K bytes away from the stack. Ignoring any memory used to hold the program instructions, what is the minimum number of pages of physical memory this function will need to not swap pages to disk? Briefly explain your answer (e.g., what is on each page).
