![]() ![]() Simple voltage-comparator types of circuits can be used to monitor fixed supplies but monitoring variably loaded high-accuracy supplies requires more sophisticated solutions involving analog-to-digital conversion of voltage levels.īesides tightly controlled operating voltages, many of today's systems also rely on thermal management approaches, such as the cooling provided by active heat sinking, convection cooling and forced air cooling to maintain reliable operating conditions. In order to maintain long-term reliability, all these voltages must be accurately monitored and controlled. In addition to the requirements of the processor chip, a typical system will require at least 4 other regulated supplies, +12V, -12V, +5V, and +3.3V, for other functions, such as disk drives, video circuitry, PC cards etc. Controlling the voltage to this degree is not a trivial requirement when one considers the dynamically varying nature of the currents flowing through the resistance and inductance of the printed-circuit-board (PCB) traces. The actual voltage required depends on a number of factors. Instead, the Pentium core logic demands digitally adjustable voltages ranging from 1.3 to 3.5 V with 50-mV resolution. The newest Pentium II microprocessors running with clock rates in excess of 450 MHz require complex, highly regulated supply voltages - a simple +5 or +3.3-V power supply no longer suffices. The latest generation of Intel Pentium-based products clearly demonstrates the importance of hardware monitoring and control. System performance can be maximized by closely controlling these parameters to remain within tight limits so as to maintain optimum operating conditions for the circuitry and avoid reduction of component life. The feedback portion of the control loop is accomplished by hardware monitoring - the continuous measurement of critical system parameters, such as power supply voltages, internal temperatures, cooling fan performance, and other environmental factors. Examples include the need to maintain accurate supply voltage levels and continually dispose of the heat generated by high-performance chips. We will consider techniques for making accurate measurements and offer solutions for the range of hardware monitoring tasks in Pentium II-based systems as embodied in the ADM9240 chip.Īs designers of ICs and systems seek to squeeze every last morsel of performance out of their designs, hardware monitoring and control have become an integral part of circuit board design objectives. This article will focus on accurate voltage and temperature monitoring as well as serving other hardware monitoring requirements. However, for businesses in need of a hardware monitoring tool, the SolarWinds Server and Application Monitor and the Paessler PRTG Network Monitor are considered to be among the best options available.įor users who want to monitor the performance of their normal PC, some of the best hardware monitoring tools to download are Open Hardware Monitor, HWMonitor, and HWiNFO.Management of the electrical, mechanical, and thermal environment is of growing importance in today's microprocessor based systems. The choice of the best PC monitoring tool varies for each user depending on their specific requirements. ![]() What are the best PC monitoring tools to download on Windows PC?
