MicroJvm® Virtual Machines

IS2T has developed a comprehensive range of Java Virtual Machines, with unique capabilities and features. MicroJvm can execute standard Java code on small and medium processors, like 8-bit, 16-bit and low-end 32-bit architectures.

IS2T has broken several technological barriers that prevented Object Oriented technology from being used on resource-constrained devices. Whereas Java is traditionaly 32-bit oriented, IS2T succeeded in providing constrained MCU architures with Java technology. MicroJvm virtual machines are the best examples of this technological breakthrough!

Tailor-Made Virtual Machines

A standard JVM does not exist at IS2T. Instead we generate a new Virtual Machine MicroJvm® for each architecture we target to make sure we can implement each important and specific hardware feature provided by the hardware.

Since we have created and own every piece of the technology we offer, we can add features, adapt, and customize our solutions to your needs. IS2T goes beyond the simple production of its products by specifically tailoring its technology for customers from a wide variety of industries. It is from this base that IS2T develops its products to more specific and customized applications.
