Suppose a malloc implementation returns 8-byte aligned addresses and uses an explicit free list where the next and previous pointers are each 32-bits. Blocks have a 32-bit header and 32-bit footer, where the low-order bit of the header and footer are used to indicate whether the block is allocated (1) or free (0). Furthermore, the block size (which includes the header, payload, footer, and any necessary padding) is rounded up to the nearest multiple of 8, and this size (in bytes) is stored in the header and footer. Assume any padding must be between the payload and the footer. a)If we call malloc(1), what block size will be allocated, in bytes? b)Using the same condition, assuming we've already called malloc(1), if the heap used by malloc starts at address 0x4000 (16384 in decimal), what address would be returned if we then called malloc(32)?

For a data segment there are 2 lists in the following memory demonstration(from 0007 offset address) with 5 elements called LIST1(list type:byte) and another list with 4 elements called LIST2(list type: Word), respectively. a) write how registers change when the following code is executed. MOV DI,2 DI = LEA BX, LIST2 BX = MOV DX, [BX][DI]+1 DX = MOV BX, OFFSET LIST1 BX = INC DI DI = SUB BX, DI BX = MOV CL, LIST1[BX] CL = b) Write code that copies 1 byte sized data that is in 0014 address, from 000DH address. c) Write code that copies 3rd element of LIST2 to 0th element of LIST2.

Program binaries in many systems are typically structured as follows. Code is stored starting with a small fixed virtual address such as 0. The code segment is followed by the data segment that is used for storing the program variables. When the program starts executing, the stack is allocated at the other end of the virtual address space and is allowed to grow towards lower virtual addresses. What is the significance of the above structure on the following schemes: a. contiguous-memory allocation b. pure segmentation c. pure paging
