The trend of IP core reuse has been accelerating for years because of the increasing complexity in the System-on-Chip (SoC) designs. As a result, many IP cores of different types have been produced. Meanwhile, similar to the free software movement, an open core community has emerged because some designers choose to share their IP cores by using open source licenses. The open cores are growing fast due to their inherently attractive properties like accessible internal structure and usually no cost for license. Under this background, the master thesis was proposed by the company ENEA (Malmö/Lund branch), Sweden. It intended to evaluate the qualities of the open cores, as well as the difficulty and the feasibility of building an embedded platform by exclusively using the open cores. We contributed such an open core platform. It includes 5 open cores from the OpenCores organization: OpenRISC OR1200 processor, CONMAX WISHBONE interconnection IP core, Memory Controller IP core, UART16550, and General Purpose IOs (GPIO) IP core. More than that, we added the supports to DM9000A and WM8731 ICs for Ethernet and Audio features. On the software side, uC/OS-II RTOS and uC/TCP-IP stack have been ported to the platform. The OpenRISC toolchain for software development was tested. And a MP3 music player application has created to demonstrate the system. The open core platform is targeted to the Terasic’s DE2-70 board with ALTERA Cyclone II FPGA. It aims to have high flexibility for a wide range of embedded applications and at the same time with very low costs. The design of the thesis project are fully open and available online. We hope our work can be useful in the future as a starting point or a reference both for academic research or for commercial purposes.

Compara-se, de um lado, como a empresa Intel têm registrado seus microprocessadores em licenças proprietárias e investido numa indústria internacional para comercialização de microcomputadores de conhecimento técnico restrito às empresas inventoras. De outro lado, como a comunidade OpenCores têm registrado seus microprocessadores em licenças livres e participado de um movimento internacional que disponibiliza integralmente o conhecimento técnico e gera capital a partir da prestação de serviços de montagem e manutenção em microcomputadores. Como referenciais teóricos para compreensão dos conceitos de tecnicidade e de capital, das formas de trabalho e da geração de valor, são estudadas as obras Do Modo de Existência dos Objetos Técnicos, de Simondon, e O Capital, de Marx. / Abstract: The object of this dissertation is the study of the relationship between technicality and capital from the Intel's development of microprocessors, in the period 1971-1999, and the Open Cores' development of microprocessor, in the period 1999-2013 ¿ the first a worldwide company, the second an international community of free hardware ¿ and how both had converted such technical objects in capital. It is compared, on one side, how Intel has registered its microprocessors in proprietary licenses and invested in an international microcomputer industry, in which technical knowledge is restricted to inventors companies. On the other hand, how the community OpenCores has registered its microprocessors in free licenses and participated of an international movement that offers full technical knowledge at the same time while generates capital by providing installation and maintenance services in microcomputers. Finally, here, as reference for theoretical understanding of the concepts of technicality and capital, the kinds of labor and value generation, are studied the work of Simondon, The Mode of Existence of Technical Objects, and the work of Marx, The Capital / Mestrado / Sociologia / Mestre em Sociologia
