Pengertian Sistem Embedded
• An embedded system is a special computer system
built into a larger device [1]
• Hardware & software which forms a component of
some larger system and which is expected to
function without human intervention[2]
• An application that contains at least one
programmable computer (uC, uP or DSP) and which
is used by individuals who are in the main, unaware
that the system is computer based [3]
• Any computer system hidden in any products [4]

Sistem embedded vs Komputer desktop (1)
(Dari Arnold S Berger, Embedded System Design)
Embedded
Desktop
Fungsi khusus
Fungsi umum
Banyak pilihan prosesor (dari 8 bit
sampai 64 bit)
Pilihan prosesor terbatas (Pentium,
AMD, PowerPC dsb)
Cost sensitive (harus murah)
Sedikit Mahal
Real time
Operating System umumnya realtime OS / RTOS
Operating System umumnya tidak
harus real-time OS : Unix,
windows
Kegagalan sistem umumnya
berakibat serius
Kegagalan tidak berakibat fatal

Sistem embedded vs Komputer desktop (2)
Embedded
Desktop
Daya terbatas (batere, solar cell)
Daya dari jala-jala
Sering dioperasikan pada tempat
yang alamnya kurang bersahabat:
Luar angkasa , Tengah laut,
Tempat dingin/panas
Sering dioperasikan di tempat
yang alamnya bersahabat
Sumber daya terbatas : RAM,
ROM, CPU
Sumber daya banyak: RAM
besar ,ROM besar, CPU cepat
Program disimpan di ROM
Program disimpan di hard disk /
magnetic media
