Current state-of-the-art in one of the EECS - Research Paper Example The move is driven by the existing gap between designer’s productivity and DSP increased complexity. As microprocessors, digital signal perform data manipulation and mathematical calculations and are characterized by real time digital signal processing competencies as data is processed in real time, high throughput, software re-programmability and deterministic operation. Despite appearing in the market in the early 1980s, DSP have numerous applications and have become key enabling technology for numerous electronics products in fields like automotive, instrumentation and military, multimedia and electronics products. Since the 1980s, DSPs have undergone extreme evolution namely in terms of hardware features, software development tools and integration. Hardware evolution occurred in two phases which are the development phase and the consolidation phase. The development phase took place until 1990 when DSP was characterized by fixed width instruction set. From 1990 to date, DSP hardware consolidation has seen development of parallel architectures, multiprocessing support, fewer manufacturers, specialized families and improved debug potential. Very Long Instruction Word VLIW and Single Instruction Multiple Data or SIMD emerged during DSP consolidation period and introduced parallelism that enhanced DSP performance. Conversely, DSP software tools have improved in a spectacular way as code compilers have evolved to effectively deal with the underlying hardware complexity and increased DSP architecture. The enhanced code compilers enable the developer to efficiently use high level languages to program more and at improved efficiency. Today, advanced programming tools like Matlab and LabView DSP module, enable the graphical DSP programming through interconnection of pre-defined blocks that are later converted into DSP code while high performance simulators, debugging and emulator facilities provide the developer with high DSP visibility with little or no inter ference on the execution of program. Through their recent associated numerous changes, programmable DSPs have become not only a rising star but also one of the fastest growing segments within the industry of processors. New developments in DSP that will influence future chip designs Today’s automobiles are experiencing a revolution that has seen gradual elimination of systems that are purely analog electronics and mechanical. Consequently, the automobile industry is gradually turning digital and incorporating dozens of embedded processors whose connection is through multiple digital networks that are optimizing and controlling nearly all operations. Hori (1) reveals that the automobile industry will experience more advancement in future car generations while the development of complex algorithms for signal processing will contribute in advancing emission and engine control, safety, driver interfaces, and in-cabin information and entertainment or infotainment. Despite the incr easing applications of DSPs in automotives, the selection of automotive processor is influenced by factors such as automobile qualification, on-chip integration, prices, performance, and efficiency of energy use. The automotive DSPs selection is also

A Friendship and Betrayal - Essay Example At the same time, the friend needs to be supportive, come what may, even if you do something wrong and this something comes back to bite you, so to speak. So, honesty and loyalty are the most important qualities when it comes to a friendship. Then, of course, there are other things to look for – compatible personalities, a shared sense of humor and a shared interest in activities are good things to look for as well. These are the same qualities that I look for in a boyfriend. Loyalty is an important aspect of friendship in general. It is important that a person not take positions that will undermine you, that a person does not steal from you, and that they did not betray you in any way. Of course, as I stated before if you are doing something which is immoral, wrong or illegal, the friend should not support that, but, other than that, a friend should be loyal, and this is universal. Disloyalty generally means that the person is not a true friend. One day, I found out that my b oyfriend and my best friend were sleeping together. And they were doing it in my apartment, while I was away at work. Right away, I decided to end both the friendship and the relationship with my boyfriend. If they wanted to be together, then they could be together, but I would no longer be a part of their lives. This was the ultimate betrayal, and I did not think that I could look past it. As I said, loyalty and honesty are the two biggest traits that a good friend must have, and my best friend showed that she was neither loyal nor honest when she did this to me. I was especially hurt because my friend had recently lost her baby through miscarriage, and I was totally there for her during this period of time. She had an ectopic pregnancy, which means that her baby was growing in her fallopian tube and not the womb, so the pregnancy was actually life-threatening. I went to the hospital with her and stayed with her after she arrived home because she was an emotional mess at that point . I called her every day to make sure that she was feeling okay. I felt that she was profoundly disloyal, and that really hurt. It was several weeks before I would take her phone calls. I heard it through the grapevine that she and my boyfriend did not last, and that my boyfriend had found somebody else. I felt that this was karma for my friend because she hurt me and now she was hurting too. Still, I was feeling sad and lonely, and my friend was calling me several times a day and leaving messages, so I finally picked up and we talked. She told me that she was suffering from severe depression, and her doctor had put her on medication. The depression stemmed partly from her lost pregnancy, but it turns out that the problem went even deeper than that. She was clinically depressed, which means that she had a chemical imbalance in the brain, and she was getting treatment for that. She did not have an excuse for sleeping with my boyfriend, except to say that she was lonely and he was the re. I could feel that she was needy, and I could understand why. She was vulnerable, and my rat of a boyfriend took advantage of that. Really, my boyfriend is the person who deserved all the blame in this situation. I wrestled with whether I would let this person back in my life. I thought about all the good times we shared because we had been friends for many years.
