Performance is a topic that never strays far from the mind of most embedded systems developers. However, relatively speaking, many of us have it easy. We develop soft real-time systems in which a few ...

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 ...

A technical paper titled “CV32RT: Enabling Fast Interrupt and Context Switching for RISC-V Microcontrollers” was published by researchers at ETH Zurich and University of Bologna. “Processors using the ...

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 ...

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 time it takes to service an interrupt. It becomes a critical factor when servicing real-time functions such as a communications line. See UART overrun. THIS DEFINITION IS FOR PERSONAL USE ONLY.

Designed for operating at temperature extremes of −40°C to 85°C, the Stratus-X-ND 16-bit PC/104 data-acquisition (DAQ) card features a 1-Msample buffer to eliminate interrupt latency issues and ...

There's an interrupt service routine invoked when the 16 bithardware timer overflows. The ISR services the hardware, increments aglobal variable named timer_hi, and returns. Therefore, timer_hi ...
