K
virtual machine (KVM), in a Java context, is a deprecated Java virtual machine
(VM) from Sun Microsystems, which is now owned by Oracle Corp. It is designed
for resource-limited devices such as cell phones, set-top boxes, personal
digital assistants and point-of-sale terminals. The "K" in KVM stands
for kilobyte, signifying the small memory space of only a few hundred kilobytes
required by the virtual machine.
For a long time, the
KVM was employed by developers creating mobile applications using the Java 2
Platform Micro Edition. This low-footprint virtual machine was targeted at
devices with 16- to 32-bit processors coupled with a total memory footprint of
about 256 KB. It has now been replaced by the connected limited device
configuration HotSpot VM.
The KVM specification focused on the following characteristics:
The KVM specification focused on the following characteristics:
- Optimized for limited resources
- Portable to different platforms
- Modular
- Extensible
Its platform portability allowed it to run on
a wide range of devices.
