Gupta 8 “Commodity” Components Hardware –microprocessor and DSP “cores” –network interfaces (PCI bridges) –video, audio engines: compression, decompression –data encryption engines –modems Software –encryption procedures –device drivers, I/O procedures –signal and image processing –operating and runtime system These components represent significant “Intellectual Property”, i.e., products of technology, software, know- how that is subject to patents, copyrights. MEMORY Cache/SRAM or even DRAM Processor Core DSP Processor Core Graphics Video VRAM Motion Encryption/ Decryption SCSI EISA Interface Glue PCI Interface I/O Interface LAN Interface Hub Architecture Commodity Software: - encryption/decryption - device drivers - legacy code - operating/runtime system Commodity Hardware: -compression -encryption -modem -signal proc. -image proc.

Gupta 9 A New Opportunity ICs on a PC board => Cells on an IC (Chip) Rich cell libraries of pre-designed, pre-verified components Technology import, technology leverage Highly integrated, compact, portable end products Reuse design blocks across systems/chips Quickly differentiate/personalize systems Significantly reduce time-to-market

11. © 1998 R. Gupta 10 Creating A New Market “Third Party IP Providers” Combine traditional roles of “EDA”, “ASIC” and “Foundry” services. Provide design specifications Synthesizable cores, design documentation Implementation guidance Examples: –Virtual Chip Group of Phoenix Technologies –Mentor’s 3Soft, DSP Group, Zoran, VLSI Cores –Sand Microelectronics, ASIC Intl., Eureka Technologies, VAutomation Inc, Western Design Center, Symbios, LogicVision, Palmchip,...

12. © 1998 R. Gupta 11 Describe technologies important to embedded systems –what is involved in system design –what are the steps, and where are the bottlenecks Describe the state of the art –existing concepts and established tools –research ideas and where are we heading in embedded system design? These lectures will not: describe detailed algorithms describe detailed designs using cores. Tutorial Goals
