(30 pts) In addition to the default IEEE double-precision format (8 byte 64 bits) to store floating-point numbers, MATLAB can also store the numbers in single-precision format (4 bytes, 32 bits). Each value is stored in 4 bytes with 1 bit for the sign, 23 bits for the mantissa, and 8 bits for the signed exponent: Sign Signed exponent Mantissa 23 bits L bit 8 bits Determine the smallest positive value (expressed in base-10 number) that can be represented using...

Be sure to consider the possibility of overflow. • [2 pts] 10101010 + 00110011 • [2 pts] 10101010 – 00110011...
Let's start with a memory system that is byte addressable and has 14-bit addresses. Now let's add a direct mapped cache that can hold 16 blocks (or has 16 lines) and each block is 4 bytes. The table shoun below details the contents of the cache at a particular point in time. if the valid bit is 1 there is a cache block loaded into the cache with Tag as detailed in the tag column. The columns B0-D3 then show...

Problem #6 (15 points) A 12-bit hamming code was generated from an 8-bit code using the format as follows Original 8-bit value Modified 8-bit value (12-bt hamming code format) 10 9 C3 co The 12-bit hamming code was transmitted over a communication channel. An error may or may not have occurred during the transmission. The received 12-bit values were shown as follows: Received 12-bit value 10 Determine whether an eror had been occurred,...
Write a program that implements an elementary bit stream cipher. An elementary level bit stream cipher is an encryption algorithm that encrypts 1 byte of plain text at a time. This one uses a given 4-bit bit pattern as the key. The size of the encrypted message that we want to be able to send has a maximum length of 200 characters. You must: 1. prompt the user to input the clear text to be encrypted. You must use printf()...
(3 pts) This problem tests your knowledge about coding schemes. What is the binary bit pattern for the letter 'h' using? The answers should give the whole bit string (including leading 0s). ASCII encoding (7-bits) EBCDIC encoding (8-bits) UNICODE encoding (16 bits) ______________________________________________________________________________ (3 pts) Show how each of the following floating point values would be stored using IEEE-754 single precision (be sure to indicate the sign bit, the exponent, and the significand fields): (show your work) 12.5 −1.5 0.75 26.625...
Write a program that allows the user to enter an unsigned integer (the maximum value of an unsigned 4-byte int is 232 = 4,294,967,296) and reverses its format (from little to big endian, or vice versa). Print out the user-entered number in hexadecimal and binary, reverse the endianness, and print the reverse in hexadecimal and binary. Integers in most machine architectures are represented in little endian format: the least significant byte is stored in the smallest address; for instance, the...

The sum of the two 32 bit integers may not be representable in 32 bits. In this case, we say that an overflow has occurred. Write MIPS instructions that adds two numbers stored in registers Ss1 and Ss2, stores the sum in register $s3, and sets register Sto to 1 if an overflow occurs and to 0 otherwise. 5. (16pts) 6. Show the IEEE 754 binary representation of the number -7.425 in a single and double 7. If...
