The associative memory formed by the four column vectors x1, x2, X3, and x4 is given by (a) X1X2X3X4 (b) x1x1* + x2x2* + X3X3'+ X4X4 (c) x1*x1 + x2*x2 + x3%3 + X4x4* (d) x1x1 - x2*x2 - x3'x3 - x4x4*

The ALU unit of a microprocessor manipulate logically or arithmetically on array of Bits. Below are two set of Bits equations placed in the ALU sequentially: Calculate 11100011 AND 11001110 and Calculate 01010111 OR 11001100 By your reasoning and application of principle of ALU solve this equations step by step

Computer Science Consider the following code: lb x6, 3(x7) sd x6, 8(x7) Assume that the register x7 contains the address (>10000000 and the data at address (>10000000 is: 0x11223344CCDDEEFF, while the data at address (>10000008 is: 0xF1E2D3C4B5A69780. Q1: What value is stored in 0x10000008 on a MIPS (big-endian) machine? Q2: What value is stored in 0x10000008 on a RISC-V (little-endian) machine?

Part A: Using a writing speed of 800 Mbits/s, how long would it take to store a 40 GB raw video file on a blue ray disk? How small would the 40 GB raw video file become if it is compressed with a compression ratio of 8. Part B: Taking the speed of the radio signal as 3×100 meters per second, calculate the time taken for a signal to reach a GPS receiver from a GPS satellite at a position 20000 km distant from the receiver. Assume that the speed of the signal is unchanged over the whole path length. Express your answer in milliseconds.
