CISC Architecture The examples of CISC architecture are: - IBM 370/168 - Intel 80486 - VAX 11/780 2. RISC Architecture The examples of RISC processors include alpha, AVR, ARM, PIC, PA-RISC and power architecture. 6.0 CONCLUSION The distinction amongst RISC and CISC chips is getting smaller and smaller. What tallies is the means by which quick a chip can execute the directions it is given and how well it runs existing programming. Today, both RISC and CISC makers are doing everything to get an edge on the opposition.

In CRC, a sequence of redundant bits, called cyclic redundancy check bits, are appended to the end of data unit so that the resulting data unit becomes exactly divisible by a second, predetermined binary number. Error correction code (ECC) techniques have been widely used to correct transient errors and improve the reliability of memories.here we were tried for FFT. Figure 7:synthesis diagram of SOS based ECC for FFT. The figure 7 is desinged by using verilog language with xilinix synthesis tool.for this design we had to use 4 to 8 bit Fault FFT with ECC Concept. The ECC codes utilize the less area than previous module.
This polymorphic instance generates Fibonacci pseudonoise (PN) bit sequences. The selected pattern is repeated until the user-specified number of total bits is generated. Use this instance to specify a PN sequence order based on which the VI selects a primitive polynomial that returns an m-sequence. Use this instance to specify the primitive polynomial that determines the connection structure of the linear feedback shift register (LFSR). total bits specifies the total number of pseudorandom bits to be generated.
section{Evaluation} label{sec-analyze} vspace{-0.08in} We evaluate Tarax with the six popular server applications described above. We first perform experiments to compare the performance and code sizes of the Tarax-optimized kernels and the vanilla kernel. We then perform dynamic profiling on the kernels to collect detailed statistics on instruction cache misses and branches. Finally, we switch on specific GCC optimizations with and without profile feedback, respectively, to collect performance numbers.
xor ax, ax ; Make the ax register 0. Remember the exclusive or when both operands are the same is always 0. mov ds, ax ; ds = ax mov ss, ax mov sp, 0x9c00 mov es, ax mov ax, 0xb800 ; 0xb800 is the address where the bootloader or kernel writes in the video memory mov es, ax ; ax contains the video memory address and es = ax. mov si, msg ; adds the string 'msg ' into the source index register. (msg is defined below) call sprint ; invokes the sprint function (sprint is defined below)
To One: Each user-level thread maps to kernel thread Many to Many: Multiples many user-level threads maps to a smaller kernel thread. 23. Using the program below, identify the values of pid that will be printed at lines A, B, C, and D. (Assume that the actual pids of the parent and child are 9600 and 9750, respectively.) #include
1. Give an example in which the operating system would use a bitmap to manage resource. Answer: Windows, Android like operating systems uses bitmap to manage resources. 2.
The USS Yorktown The USS Yorktown is a fantastic example of a terrible mistake made by the engineers that programmed the ship. The number zero proved that it was very powerful, and that it should not be overlooked so quickly. The USS Yorktown was a test-bed for a program in the Navy known as the Smart Ship program. The reason the ship crashed was because the ship tried to divide by zero.
1) What is modularization, and why do we want to do this?? Design It is an approach to program design that involves developing complex programs not as “contiguous structures” but as assemblages of self-contained parts or “modules”. The modules usually enclose one independent point of functionality relative to the total functionality of the program.
Examples of logos are statistics, facts, evidence, and anything logical. In Serial, Sarah uses lot of logos because she’s reexamining a murder case, that was technically already closed. An example of Sarah’s use of logos is when she says “Here’s what he’s talking about. In both of Jay’s taped statements, there’s a before. A period of time before the tape recorder is turned on.
3.1.1 Dual Clock In this technique it is assumed that delay misses rarely happens, then circuit schedules are designed using minimal delays for critical paths. Pair of alternate clocks, fast and slow, is used. The system normally operates at the fast clock however, when an error is noticed, computation for the input values which is causing error is restarted at the slower clock. Under the premise that delay errors occur for small number of input values, the system can switch back to the faster clock on the next input value.
If there are so many programs, and the resources are limited, this software called (kernel) also decides when and how long a program should run. It is also called scheduling. It might be very complex to access the hardware directly, since there’re so many different hardware designs for the same type of components. Usually kernels implement somehow level of hardware abstraction to hide the underlying complexity from applications and provide a uniform interface. This also helps application developers to develop
#19 a) Since the code contains 6 bits and each machine language contains 2^n the number would be 64. b) The maximum size of the memory on the 18 bit machine is 2^18 =262144 c) 8 bits is equal to 1 byte, therefore each operation requires 48 bits. #3 A program written in assembly language is the source program, which would be the English letter.
Now all of the subsystems have their respective schematics and diagrams and an easy to follow system

2.4 Experiential Architecture Sensorial Experiences While the importance of a sensory rich environment is obvious to most, in contemporary designs, attention to the senses is usually limited to sacred spaces. While they play just as important a role in everyday spaces, they are often left out of design considerations. Touch, smell, and other sensations are key in what we call experience. They are the receptors with which we move through and understand space.
