## Programmable Logic Technology

Earlier, the designing of logic circuits can be done using SSI small scale integration components like logic gates, multiplexers , de-multiplexers, FFs, etc.

Indicate which of the following logic gates can be used to realized all possible combinational logic functions : a. In digital electronics both combinational and sequential circuit are the most widely used circuits. Preparation Read lab lecture notes which contains the Combinational Design Procedure. Submit your answers and see how many you get right. A combinational logic circuit is a circuit whose outputs only depend on the current state of its inputs.

Answer: A digital system is a combination of devices designed to manipulate logical information or physical quantities that are represented in digital form that is the quantities can take only discrete values. Example of digital systems includes digital computers and calculators, digital audio and video equipments etc. An analog system contains devices that manipulate physical quantities that are represented in analog forms. In an analog system, the quantities can vary over a continuous range of values. Answer: A digital signal is defined as a signal which has only a finite number of distinct values. Digital signals are not continuous signal, they are discrete signals. If a digital signal has only two distinct values, i.

Follow-up question: now, comment on what each of these acronyms actually means, going beyond a mere recitation of the definition. Going into the precise meaning of each acronym may not be the best use of time in answering this question, as there is little context in which to understand the meanings. This question is intended only as an opening to an in-depth discussion of programmable logic, and not an end in itself! Are there any applications where hard-wired logic would do a better job than a programmable device? Ask your students to share where they found their information on programmable devices, and how they determined the advantages and disadvantages of this technology compared to hard-wired logic. Perhaps the simplest form of programmable logic is a PROM integrated circuit, programmed with a specific truth table. Describe what the truth table would look like for the data we must program into this memory chip.

## Programmable Logic Devices

Programmable Array Logic PAL is a family of programmable logic device semiconductors used to implement logic functions in digital circuits introduced by Monolithic Memories , Inc. MMI in March The trademark is currently held by Lattice Semiconductor. PAL devices consisted of a small PROM programmable read-only memory core and additional output logic used to implement particular desired logic functions with few components. Using specialized machines, PAL devices were "field-programmable".

These are also implemented in IC. ROM design was not very successful as it emerged the issue of hardware wastage and increasing exponential growth in the hardware for every large application. Availability Less prolific More readily available Flexibility Provides more programming flexibility.

There are three kinds of PLDs based on the type of array s , which has programmable feature. The process of entering the information into these devices is known as programming.

У нас осталось всего восемь минут. Мы ищем число, а не произвольный набор букв. - Четыре умножить на шестнадцать, - спокойно сказал Дэвид.  - Вспомни арифметику, Сьюзан. Сьюзан посмотрела на Беккера, наблюдавшего за ней с экрана. Вспомнить арифметику.

В обычных условиях такое действие считалось бы недопустимым. Но в сложившейся ситуации никакой опасности в загрузке в ТРАНСТЕКСТ этой программы не было, потому что коммандер точно знал, что это за файл и откуда он появился. - Несмотря на все мое уважение к вам, сэр, - продолжал настаивать Чатрукьян, - мне никогда еще не доводилось слышать о диагностике, в которой использовалась бы мутация… - Коммандер, - перебила его Сьюзан, которая не могла больше ждать.  - Мне действительно нужно… На этот раз ее слова прервал резкий звонок мобильного телефона Стратмора. Коммандер поднес его к уху.

Она встала, но ноги ее не слушались. Надо было ударить Хейла посильнее. Она посмотрела на беретту и внезапно почувствовала тошноту.

Четыре на шестнадцать, - повторил профессор. - Лично я проходил это в четвертом классе. Сьюзан вспомнила стандартную школьную таблицу. Четыре на шестнадцать. - Шестьдесят четыре, - сказала она равнодушно.

Вы должны немедленно покинуть шифровалку. Немедленно. Это приказ. Чатрукьян замер от неожиданности. - Но, сэр, мутация… - Немедленно! - крикнул Стратмор. Чатрукьян некоторое время смотрел на него, лишившись дара речи, а потом бегом направился прочь из шифровалки. Стратмор повернулся и с удивлением увидел Хейла.
