Historical Development
Early Days of Embedded Systems in India
The roots of embedded computing in India trace back to the 1960s, when government agencies and defense laboratories began to adopt programmable logic devices for control and automation tasks. The Indian Institute of Technology (IIT) Kanpur and the Indian Institute of Science (IISc) in Bangalore pioneered research in microelectronics, laying a foundation for subsequent development of embedded architectures. Early commercial ventures were limited, but the establishment of state-sponsored research centers and the proliferation of basic microprocessor-based modules created an ecosystem conducive to experimentation.
Emergence of Bangalore as a Technology Hub
Bangalore’s transformation into a technology nucleus began in the 1980s, driven by a combination of favorable climatic conditions, a growing pool of engineering graduates, and the establishment of multinational technology companies. The presence of the Indian Space Research Organisation (ISRO) and the Department of Space provided early exposure to complex embedded applications such as satellite telemetry and navigation. As software development evolved, Bangalore attracted consulting firms and software exporters, which subsequently began incorporating embedded solutions into client projects, especially in the defense and aerospace sectors.
