This paper will discuss design practices and guidelines that will maximize the efficiency of interrupts and interrupt handling in an embedded system IC. These practices can result in a smaller code ...

Desktop or laptop computers are extremely powerful and amazingly low cost. This means that developers of software for desktop systems assume that there is infinite CPU power, so they worry very little ...

LONDON — MIPS Technologies Inc. will present a series of enhancements to the basic MIPS32/MIPS64 instruction set architecture at this week's Microprocessor Forum in San Jose, Calif. Changes in such ...

When debugging something as involved as kernel scheduler timings, you would typically use one of the software-based debugging mechanisms available. However, in cases when software is close to bare ...

A new breed of micropro-cessor based on very long instruction word (VLIW) technology is well suited for embedded systems. This is due to the fact that VLIW architectural simplicity is achieved at the ...

Hard real-time Linux has been around for ages, or it may never appear. It all depends on who you talk to. It also depends on your requirements. A two-second interrupt latency may be acceptable for ...

Infineon's TriCore hybrid 16/32-bit processor is now supported by the OSE Epsilon real-time operating system (RTOS). OSE Epsilon requires as little as 4 kbytes of memory and has a context switch speed ...

When do you need to use a real-time operating system (RTOS) for an embedded project? What does it bring to the table, and what are the costs? Fortunately there are strict technical definitions, which ...

The open-source eCos (Embedded Configurable Operating System) is ideal for deeply embedded systems in which memory resources and real-time execution constraints are top design issues. The system ...
