For this purpose, terminal emulation allows a computer terminal to appear and function like another, usually older type of terminal so that a user can access legacy programs. In many organizations, legacy applications persist that must still communicate with the device. A printer emulator, for instance, lies within the printer's ROM. Hardware emulation can be useful when a hardware device or peripheral like a printer, scanner or digital camera becomes obsolete. In hardware, emulation is the use of hardware to imitate the function of another hardware device for the purpose of connecting devices to one another or connecting to a mainframe computer. A virtual environment can also be referred to as a partition, guest, instance or container.ģ. In server virtualization, emulation is a synonym for virtual environment. TIOCLENABLEFP64 The C66x DSP is double precision floating point capable and all the optional features in the OpenCL specification for double precision floating point are supported in this OpenCL implementation, except for the requirement that double FP support include subnormal behavior or graceful underflow.

Virtual PC is another example of an emulator that allows Macs to run Windows XP, though the addition of Boot Camp to next-generation Intel-based Macs has removed the need for that application in the Macintosh environment in the future.Ģ.

Running application programs on different operating systems other than those for which they were originally written.Ī common example of that last type of emulation is running Windows applications on Linux computers.

Running legacy applications on devices other than the ones for which they were developed.

Running arcade or console-based games upon desktop computers.

Running an operating system on a hardware platform for which it was not originally engineered.

Emulation, in a software context, is the use of an application program or device to imitate the behavior of another program or device. But this library should be very efficient because compiler's libraries often have assembly level optimization for their own type of float.1. No need to spend time for calculating/storing the unnecessary 16 bits anymore. You can choose whatever is enough for you, for example change the library to adapt a new 48-bit float type of your own if only 40 bits of mantissa and 7 bits of exponent is needed. If you really need the longer mantissa, try using a custom floating-point library. Because of that, using float-float may not increase performance and introduce some memory overhead to save the extra bytes of exponent. However in most microcontrollers there's no hardware support for floats so they're implemented purely in software.

Posted yesterday were a set of seven patches by Intel's Ian Romanick for reducing worst-case memory. It looks like some work is still quietly progressing on the soft FP64 front. This way the calculation will be much faster than a software floating-point library. This FP64 emulation support will also help out older Intel and NVIDIA (via Nouveau) GPUs as well that lack native hardware double precision floating point capabilities. It's also used as float-float on older NVIDIA GPUs where there's no double support. This is similar to the double-double arithmetic used by many compilers for long double on some machines that have only hardware double calculation support.
