Teknologi cerdas saat ini sudah merambah dan menyebar ke setiap sudut masyarakat modern. Misalnya, satelit komunikasi dan handsetnya, kamera pendeteksi gerak pencuri, perangkat komputer cybercrime, hingga peralatan mesin cuci. Termasuk bidang instrumentasi medis, juga mengalami hal yang sama.
Tujuan utamanya, untuk memastikan adanya kualitas kehidupan yang lebih tinggi.

Sistem pengobatan saat ini sudah dilengkapi dengan sinyal dan gambar (image) yang didapat dari tubuh manusia, model kompleks dari sistem fisiologis dan perlengkapan dari perangkat maupun prosedur terapi.
Pengamatan seksama terhadap proses ini menunjukkan adanya kelambatan pengambilan keputusan dari kegiatan tenaga medis.

Untuk mengatasinya, seluruh informasi pasien diintegrasikan menjadi satu bentuk yang ringkas dan interpretatif
Ketersediaan adanya uP, uC dan PC dengan kinerja yang tinggi, yang menawarkan adanya sistem manajemen dan monitoring yang cerdas dan efisien bagi pasien, memberikan kekuatan dan nilai tambah tersendiri bagi tenaga medis profesional.

The Microprocessors (1)
The microprocessor classifications:
1. based on the word length of memory addressing 2. the word length defines the basic resolution 3. 8 bit uP will perform 8 binary digit (0–255 dec) 4. 12 bit uP will perform 12 binary digit (0–4095 dec) 5. 16 bit uP will perform 16 binary digit (0–65535 dec) 6. have a powerful speed of operations
