"At the heart of CLDC is Sun's K virtual machine (KVM), a virtual machine designed from the ground up with the constraints of inexpensive mobile devices in mind. Named to reflect that its size is measured in the tens of kilobytes, CLDC is suitable for devices with 16/32-bit RISC/CISC microprocessors/controllers, and with as little as 160 KB of total memory available -- 128 KB of which is for the storage of the actual virtual machine and libraries themselves."
