1. The MIPS instruction set includes several shift instructions. They include logical-shift-left (sll), logical-shift-right (srl), and arithmetic-shift-right (sra). [2 +2 4 points] a) Why does not MIPS offer an "arithmetic-shift-left (sla)" instruction? b) Write a MIPS code to implement the logical-shift-left (sll) instruction for a machine that did not have this particular instruction? In other words, you have to write the equivalent of the sll instruction using mul, add and other instructions. Try writing the equivalent of sll Ss1, Ss2,...
2. Serial shift registers Draw missing connections to implement various shift registers 1. Shift right: All bits of the register move right by one position, and a new bit value from a serial input is stored in the most significant bit (leftmost flip-flop below). Serial input -02 az 02 a Do ao Serial indino 2. Shift left: All bits of the register move left by one position, and a new bit value from a serial input is stored in the...
2) Create the logical right shift circuit in VHDL. Using the & operator for concatenation might make things easier. For example, if A is a 4 bit input, the number “0”&A(3 downto 1) is A shifted one place right. The & operator sticks a zero onto the three most significant bits of A, A(3 downto 1). A(0) is lost, as expected. You must use std_logic_vectors with the & operator. “0” is a one bit std_logic_vector. A(3 downto 3) is also...
What is the differences between PM and PA? Performance management and Performance apraisl. Please explain in details and give some examples. And how to implement them.
what are the similarities and differences between an arithmetic sequence and a linear equation?ok i know that arithmetic sequence is a sequence of real numbers for which each term is the previous term plus a constant (called the common difference). For example, starting with 1 and using a common difference of 4 we get the finite arithmetic sequence: 1, 5, 9, 13, 17, 21; and also the inifinite sequence 1, 5, 9, 13, 17, 21, 25, 29, . . .,...
Operating Systems Name two differences between logical and physical addresses. Why are page sizes always powers of 2? Consider a logical address space of 64 pages of 1,024 words each, mapped onto a physical memory of 32 frames. a. How many bits are there in the logical address? b. How many bits are there in the physical address?
FIRST ACTIVITY: (100/100) . SIMPLE 4-BIT ARITHMETIC LOGIC UNIT (ALU): This circuit selects between arithmetic (absolute value, addition) and logical (XOR, AND) operations. Only one result (hexadecimal value) can be shown on the 7-segment display This is selected by the input sel (1..0) B A-BI A+B A xnor B A nand B Input EN: If EN-1result appears on the 7 segment display. If EN=0 → all LEDs in the 7 segment display are off Arithmetic operations: The 4-bit inputs A...
Implement an arithmetic logic unit (ALU) using Verilog. Consider signed number arithmetic operation. The outputs of the ALU should be 1) Addition of two 8-bit numbers 2) A Zero Flag. It is set (it is 1 if the condition is met and 0 otherwise) if the result is zero. 3) A Negative Flag. It is set (it is 1 if the condition is met and 0 otherwise) if the result is less than 0. 4) An Overflow Flag. It is...
