Real- time Kernels (RTOS)
A real- time, multi- tasking, ROMable kernel for embedded systems, C EXECUTIVE is available for 8-,
16- and 32- bit CISC processors, a wide variety of RISC processors, and DSP. It provides fast context
switching, small kernel size, and support for over 20 processors. Optional DOS- compatible file system,
TCP/ IP, and SNMP are available. PSX provides an optional subset of POSIX. 1 system calls.
•Scalability
C EXECUTIVE is inherently scalable, since the system calls are linked in from a library during a system build. Only those system calls which are used by the application are linked into the system executable image. In addition, the kernel can be configured with or without timeslicing, clock support, signals, etc., allowing a highly optimized system configuration for small target systems.
•Customer Applications
JMI’s real- time kernels are used in hundreds of embedded applications, including laser printers, electronic cash registers, medical instruments, communication devices, military and aerospace applications, and many other time critical systems. Pictures and descriptions of some customers’
products are available in our product photo gallery.
