Which microprocessor is used now?
Today those systems use the PowerPC chip, also by Motorola and a successor to the 68000 series. All these previous chips set the stage for the first PC processors. Intel introduced the 8086 in June 1978.
What processors are used in supercomputers?
It uses more than 80,000 SPARC64 VIIIfx processors, each with eight cores, for a total of over 700,000 cores—almost twice as many as any other system. It comprises more than 800 cabinets, each with 96 computing nodes (each with 16 GB of memory), and 6 I/O nodes.
What are the applications of a microprocessor?
Microprocessor-based systems are thus found everywhere today and not just in computers and smartphones: in automatic testing of products, speed control of motors, traffic light control, communication equipment, television, satellite communication, home appliances, such as microwave oven, washing machine, gaming …
How many microprocessors are there?
There are three types of microprocessors namely, CISC, RISC, and EPIC.
Does Motorola still make microprocessors?
Although no modern desktop computers are based on processors in the 680×0 series, derivative processors are still widely used in embedded systems….Motorola 68000 series.

What is supercomputer and its uses?
supercomputer, any of a class of extremely powerful computers. The term is commonly applied to the fastest high-performance systems available at any given time. Such computers have been used primarily for scientific and engineering work requiring exceedingly high-speed computations.
Where is supercomputer used?
Supercomputers play an important role in the field of computational science, and are used for a wide range of computationally intensive tasks in various fields, including quantum mechanics, weather forecasting, climate research, oil and gas exploration, molecular modeling (computing the structures and properties of …
How many bits does a supercomputer have?
32-bit processors are the standard, the first processor introduced into home computers throughout the 1990s. 64-bit processors were created first for IBMs supercomputer and weren’t introduced into home computers until the early 2000s.
What can a supercomputer be used for?
Typically, supercomputers have been used for complex, mathematically intensive scientific problems, including simulating nuclear missile tests, forecasting the weather, simulating the climate, and testing the strength of encryption (computer security codes). In theory, a general-purpose supercomputer can be used for absolutely anything.
What software tools do supercomputers use for distributed processing?
The parallel architectures of supercomputers often dictate the use of special programming techniques to exploit their speed. Software tools for distributed processing include standard APIs such as MPI and PVM, VTL, and open source software such as Beowulf .
Is there a limit to how fast a processor can work?
But there’s still a limit to how fast a processor will work and there’s only so much difference more memory will make. The best way to make a difference is to use parallel processing: add more processors, split your problem into chunks, and get each processor working on a separate chunk of your problem in parallel.
What is an example of a special-purpose computer?
Examples of special-purpose supercomputers include Belle, Deep Blue, and Hydra, for playing chess, Gravity Pipe for astrophysics, MDGRAPE-3 for protein structure computation molecular dynamics and Deep Crack, for breaking the DES cipher.
