Embedded P.C solutions to the Medical Applications and devices

By Oded Amir


With a rise in pressures to both chop the time to market and increase the number of features in their latest models, many medical equipment makers are looking towards off-the-shelf P.C boards in making these designs. Using inserted P.C boards can seriously cut back the design time of feature-rich medical equipment, but only if the feature set of the board is matched to the application.

Knowing what points to ask is vital to picking an inserted Personal computer solution. By learning more about the features available on embedded PCs, it gets simpler to grasp which things to ask.

Reasons for Using an Inserted Personal computer or ARM Base solution

During the past, it was commoner for designers to select a microprocessor or microcontroller chip, design the supporting circuitry around it, and add the special inputs and outputs needed by the application. In numerous cases, this is still a desirable trail to take. It gives the most control of precisely what features are included in the final design. Every part of the circuit in a fully customised design is there for a good reason specific to the end application. But absolutely customized designs can take substantial time to get from the drawing board to the market.

Reducing the time to market is one of the largest reasons for picking an off-the-shelf embedded PC for medical applications. If the core processor circuitry is ready to be plugged into a system, it saves on circuit design and debugging time. It also reduces the time expended on developing firmware, because embedded PCs usually already have basic input/output system (BIOS) firmware that initializes the core elements, tests critical subsystems, and loads the application program. In an increasingly competitive environment, shaving 1 or 2 months or weeks of a product development cycle can affect the success of a product.

A different reason that embedded Computers are being used more frequently is that the number of features that users expect is rapidly increasing. Though alphanumeric liquid-crystal displays (LCDs) are utilized for some jobs, for example blood sugar monitoring, it is beginning to become more commonplace for a modern piece of medical hardware to have a full-color graphical display. This permits additional information to be conveyed to the user, but at the price of enlarging the amount of computing hp needed, as well as the complexness of the software. Inserted Computers may help to solve that problem by employing the sizeable number of graphics software already available on the desktop PC.

Embedded PC- Express Features

There are numerous reasons,eg product lifetime or size, for using an inserted Personal computer instead of a desktop Computer motherboard in a medical application. But the large reason is that inserted Computers have features that are not found on desktop Computers features that encompasses the following: Digital I/O, Analogue I/O, Solid-state disks, Different system buses such as PC/104, CompactPCI, and so on.
