4. Consider a system which has logical address is 7 bits, physical address is 6 bits calculate the number of pages and no.of frames. 5. Given Memory partition of 110,510K,210K and310kand600kin that order show how each of the best-fit, worst-fit and first-fit algorithms place process of221,471,112and 426 in that order in memory.
To be able to make some predictions of disk performance, it is useful to have a model of storage allocation. Suppose that the disk is viewed as a linear address space of N» 1 sectors, consisting of a run of data blocks, then a hole, then another run of data blocks, and so on. If empirical measurements show that the probability distributions for data and hole lengths are the same, with the chance of either being i sectors as 2-¹, what is the expected number of holes on the disk?
Let's pretend for a moment that we have a byte-addressable computer with fully associative mapping, 16-bit main memory addresses, and 32 blocks of cache memory. The following holds true if each block is 16 bits in size: a) Determine how many bytes the offset field is. Measure the tag field's width and height in pixels (b).
The method to compress an image in image processing is using convolution matrix where the number of outputs is reduced by replacing the matrix multiplication with much smaller kernel matrix. This is illustrated on the figure below. In this example a black and white photograph is scanned as a rectangular array of pixels and then stored as image matrix on the left by assigning each pixel a numerical value in accordance with its gray level, (0 = white to 255 = black), then the entries in the matrix are integers between O and 255.Then multiplication is employed with much smaller kernel matrix in the middle. 0|0 21 00 o 106 85 71 1 250 231 127 63 1 250 252 250 209 56 1 250 252 250 250 83 Kernel 0 0 0 Feature map Image Boxes in red and blue frames indicate how the upper left element is formed by applying the kernel to the corresponding upper left region of the input matrix. The elements of much smaller "feature map" matrix on the right can be calculated from: 3.

write code to implement parallel matrix multiplicationC = A×B by row partitioningmatrix A and sending each process its partition and the whole of matrix B. Eachprocess performs its own multiplication and sends the partial product to the masterprocess which collects all results and then prints the product matrix C, we have 4processes including the master process. The output matrix C displayed is the product of matrices A and B.
