- 2. Page 2 LOGO The Natural Evolution of microcomputer based system instrument is toward more intelligent devices. More and more memory is being squeezed into smaller and smaller spaces (IC's) Just like Laptops Battery powered patient worn portable instrument is getting commercial. The PC has become a powerful tool in biomedical computing applications. There's possibility that in future instruments be developed which at one time couldn't be developed due to size, cost, or power consumptions.

Page 3 LOGO Evolution of microcomputer based medical instruments has followed evolution of microprocessor itself According to Moore the number of transistors that could be put on a single chip doubled every two years. PC itself has become a powerful tool in biomedical computing requirements as development of the biomedical equipments went on in parallel with the microprocessor. In near future many new medical instruments would be developed which could address many problems that couldn't be addressed earlier all this would be possible because of the rapid development of microprocessor and its continuous evolution in terms of decreased size cost and power and increased memory and computing power.

This was done by reprogramming it. -Most Successful one -First Interactive one eg. An ECG could be captured and displayed directly -It would have been the first PC if it were smaller and costed less -First Game Computer
