Description: C EXECUTIVE and PSX (small Linux-like kernel) from JMI Software Systems, Inc. are real-time, multi-tasking,ROMable kernels for embedded systems. C EXECUTIVE is available for 8-, 16- and 32-bit CISCprocessors, 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 also available. PSX provides an optional subset of POSIX.1 system calls.

PSX versus Linux
PSX provides a single-user, single-group subset of POSIX.1 system calls, and is about ONE TENTH the size of Linux, not to mention the much smaller interrupt latency. PSX does not have the overhead of fork/exec, MMU management and multi-user capability. Up to 32,000 processes and POSIX threads can be created. PSX is based on the C EXECUTIVE real-time kernel.
