16-bit or 32-bit CPU with a clock speed of 16 MHz or higher; At least 160 KB ROM allocated for the CLDC libraries and virtual machine; At least 8 KB total RAM available to the Java platform; Low power consumption, often operating on battery power; Connectivity to some kind of network, often with a wireless, intermittent connection and limited ...
For example, a multicast router may operate differently on interfaces that represent tunnels than on physical interfaces (e.g. it may only need to collect membership information for physical interfaces). Thus the virtual interface may need to divulge some specifics to the user, such as whether or not it represents a physical interface directly. [1]
Devices that support CDC typically include a 32-bit CPU with about 2 MB of RAM, and 2.5 MB of ROM available for the Java application environment.The reference implementations for CDC profiles are based on Linux running on an Intel-compatible PC, and optimized implementations are available for a variety of other CPUs and operating systems.
Note: Downloading and installing of Java will only work in Desktop mode on Windows 8. If you are using the Start screen, you will have to switch it to Desktop screen to run Java. Windows Server 2008/2003; Intel and 100% compatible processors are supported; Pentium 166 MHz or faster processor with at least 64 MB of physical RAM; 98 MB of free ...
Consequently, you can install a 32-bit or 64-bit JVM on a 64-bit operating system. The primary advantage of running Java in a 64-bit environment is the larger address space. This allows for a much larger Java heap size and an increased maximum number of Java Threads, which is needed for certain kinds of large applications; however there is a ...
The Java Native Interface (JNI) is a foreign function interface programming framework that enables Java code running in a Java virtual machine (JVM) to call and be called by [1] native applications (programs specific to a hardware and operating system platform) and libraries written in other languages such as C, C++ and assembly.
Furthermore, it is possible to simulate several virtual NICs by implementing virtual miniport drivers that send and receive traffic from a single physical NIC. One example of virtual miniport driver usage is to add virtual NICs, each with a different VLAN. Because implementations cannot assume that other drivers received the same buffers, one ...
Contiki is designed to run on types of hardware devices that are severely constrained in memory, power, processing power, and communication bandwidth.A typical Contiki system has memory on the order of kilobytes, a power budget on the order of milliwatts, processing speed measured in megaHertz, and communication bandwidth on the order of hundreds of kilobits/second.
