- Write a program for 8085 microprocessor to swap nibbles (upper four bits and lower four bits) of ten 8-bit numbers stored at 8000H transfer to new location 8050H if the numbers have D5=1 else store FFH in the destination.15. Consider the following Java-like code: int number = <<read number from user>>; int mask = MASK; int result = number OP mask; if (result != 0) { print("Bit 8 was set"); } The above code is supposed to print “Bit 8 was set” if bit 8 of user’s number was set to 1. If bit 8 was not set, then this code should not print anything (result==0). What hexadecimal value should MASK be, and what bit-wise operation should OP be, for the above code to work correctly?Write a program to sub a block of (100)10 consecutive bytes of data string at offset address 3000H in memory from the block of memory location starting at offset address (A000H).

- Implement the Hamming Code error detection and correction algorithm for a group message to be transmitted over a network. Hamming code algorithm allows the receiver to detect errors that may have been introduced due to many factors such as noise, interference, and many others. -> Assume the following: 1. The sender message length is 2 bytes. The data transmitted to the user is the 2-byte data in addition to the parity bits. 2. The receiver must be able to detect and correct 1-bit error. Report :In the report you must include an overview of the Hamming code algorithm and you need to show: 1. The detailed calculation of the minimum number of parity bits needed for a message of 2-byte length. 2. Details on how sender generates the parity bits. 3. Details on how thew receiver detects and corrects a 1-bit error.

There were no other segmentlosses apart from the aforementioned. What is the average throughputobtained in sending all the data segments (in bytes/sec)? Draw a diagramto show the communication process in detail.Suppose a malloc implementation returns 8-byte aligned addresses and uses an implicit free list. Blocks have a 32-bit header, where the low-order bit of the header is used to indicate whether the block is allocated (1) or free (0). Furthermore, the block size (which includes the header, payload, and any necessary padding) is rounded up to the nearest multiple of 8, and this size (in bytes) is stored in the header. Assume any padding must be at the end of the block. If we call to malloc(1), what block size will be allocated, in bytes?A 3400-byte datagram needs to cross a network with an MTU of 800 bytes. i.
