Omniscient Code Generation for 8-, 16- and 32-bit Microcontrollers

C-language programs are usually developed by teams of engineers who are often geographically dispersed, leading to redundant code and inconsistent variable declarations between modules. Traditional compilation technology compiles each module separately with no regard for what goes on in the other modules and with no information about how pointers, stacks, variables and functions are used throughout the whole program. Traditional compilers tend to over-allocate memory space for pointers, stacks and registers. They are unable to fully exploit the wide variety of memory maps, and register and stack configurations available in today’s microcontrollers. All too often, the programmer must resort to manual optimizations that compromise portability (Figure 1).

Using AdvancedTCA and MicroTCA in High-Availability Military Systems

The complexity of military and aerospace systems is growing — more components, interfaces, power, bandwidth, processing, features, and data — and these systems are being networked to form even more complex “systems of systems.” Modern networkcentric systems can contain hundreds, even thousands of electronic modules.

Multipurpose Transaction Protocol: A New Data Transport Model

It is no secret that high-performance and the Internet are often seen as contradictory terms. Even private IP networks see serious performance challenges once they extend beyond the local building and around the globe. As devices and their users become more mobile, it has become critical to design with high-speed, Wide Area Networks in mind. But software and hardware designers are traditionally given few choices and little control for ensuring high network performance.

Virtual Machine Manager

TenAsys Corp. (Beaverton, OR) has released the eVM™ virtual machine manager for real-time, missioncritical systems. The eVM platform simultaneously hosts embedded and real-time operating systems (RTOS) along with the Microsoft® Windows® general-purpose operating system (GPOS) on a single hardware platform using multi-core Intel® processors. eVM software partitions hardware resources and provides standard communications channels between the embedded RTOS guest and Windows, while isolating the two environments so that real-time de - terminism and the OS desktop experience are fully maintained.

The eVM virtualization system lets multiple operating systems share a single hardware platform without conflict, by partitioning hardware resources, such as CPU cores, I/O, RAM, and interrupts. By combining their existing embedded applications with Windows, on a single Intel processor-based computer, system OEMs can achieve significant manufacturing cost savings and redeploy existing real-time and embedded IA based applications without costly porting expense. eVM technology is based on TenAsys’ real-time virtualization expertise, which enables Windows to run with 100% native performance.
