“Hard Hat Linux supports popular first generation RTOS with
shortest open source path to embedded Linux.“
“MontaVista, Inc., developer of the Hard Hat Linux operating
system for embedded applications, today announced immediate
availability of a pSOS-to-Linux transition kit, easing support for
and portation of legacy code from the widely-deployed pSOS
real-time operating system with plans to include a similar kit for
VxWorks. The open-source virtual machine software and porting tools
streamline the transition to Linux for thousands of pSOS
applications in telecommunications, networking, instrumentation,
transportation, and control. To address these markets MontaVista is
delivering support for legacy RTOS code along with a family of
development tools, services, training and documentation.”
“The announcement is significant in light of the acquisition of
Integrated Systems Inc., provider of the pSOS embedded operating
system, by Wind River Systems of Alameda, CA, in late 1998. Wind
River subsequently announced the company’s transition plan for ISI
customers at the Embedded Systems Conference in Chicago, IL in
March of this year. Per the announcement, pSOS developers would
have to accompany a series of intermediate Wind River product
versions before they could fully integrate into VxWorks APIs and
tools. “While the Wind River acquisition of Integrated Systems does
represent an important consolidation in a fragmented RTOS
marketplace, it forces an unpleasant choice upon thousands of ISI
customers Ð to follow a circuitous and nebulous path from pSOS
to VxWorks, or to look elsewhere for an embedded software
platform,” comments Jim Ready, embedded industry pioneer and
president/CEO of MontaVista.”
