* Supercomputing: DRDO's ANURAG developed the PACE+ Supercomputer for strategic purposes for supporting its various programs. The initial version, as detailed in 1995, had the following specifications: The system delivered a sustained performance of more than 960 Mflops (million floating operations per second) for computational fluid dynamics programs. Pace-Plus included 32 advanced computing nodes, each with 64 megabytes(MB) of memory that can be expanded up to 256MB and a powerful front-end processor which is a hyperSPARC with a speed of 66/90/100 megahertz (MHz). Besides fluid dynamics, these high-speed computer systems were used in areas such as vision, medical imaging, signal processing, molecular modeling, neural networks and finite element analysis. The latest variant of the PACE series is the PACE ++, a 128 node parallel processing system. With a front-end processor, it has a distributed memory and message passing system. Under Project Chitra, the DRDO is implementing a system with a computational speed of 2-3 Teraflops utilizing commercial off the shelf components and the Open Source Linux Operating System.[47]
* Processors and other critical items: DRDO has developed a range of processors and application specific integrated circuits for its critical projects. Many of these systems are modular, in the sense that they can be reused across different projects. These include "Pythagoras processor" to convert cartesian to polar coordinates, ANUCO, a floating point coprocessor and several others, including the ANUPAMA 32-bit processor, which is being used in several DRDO projects.[48]
* Electronic components: one of the endeavours undertaken by the DRDO has been to create a substantial local design and development capability within India, both in the private and public sectors. This policy has led to several hard to obtain or otherwise denied items, being designed and manufactured in India. These include components such as radar subsystems (product specific travelling wave tubes) to components necessary for electronic warfare and other cutting edge projects. Today, there are a range of firms across India, which design and manufacture key components for DRDO, allowing it to source locally for quite a substantial chunk of its procurement. The DRDO has also endeavoured to use COTS (Commercial off the shelf) processors and technology, and follow Open Architecture standards, wherever possible, in order to pre-empt obsolescence issues and follow industry practise. One significant example is the development of an Open Architecture computer for the Light Combat Aircraft, based on the PowerPC architecture and VME64 standard. The earlier Mission computer utilizing Intel 486 DX chips has already seen success, with variants being present on the Su-30 MKI, Jaguar and MiG-27 Upgrades for the Indian Air Force.[49]
