Hardware-software cosynthesis for digital systems

Abstract: As system design grows increasingly complex, the use of predesigned components, such as general-purpose microprocessors can simplify synthesized hardware. While the problems in designing systems that contain processors and application-specific integrated circuit chips are not new, computer-aided synthesis of such heterogeneous or mixed systems poses unique problems. The authors demonstrate the feasibility of synthesizing heterogeneous systems by using timing constraints to delegate tasks between hardware and software so that performance requirements can be met. System functionality is captured using the HardwareC hardware description language. The synthesis of an Ethernet-based network coprocessor is discussed as an example. >

CMOS active pixel sensor type imaging system on a chip

Abstract: Single substrate device is formed to have an image acquistition device and a controller. The controller on the substrate controls the system operation.

HARPOON: An Obfuscation-Based SoC Design Methodology for Hardware Protection

Abstract: Hardware intellectual-property (IP) cores have emerged as an integral part of modern system-on-chip (SoC) designs. However, IP vendors are facing major challenges to protect hardware IPs from IP piracy. This paper proposes a novel design methodology for hardware IP protection using netlist-level obfuscation. The proposed methodology can be integrated in the SoC design and manufacturing flow to simultaneously obfuscate and authenticate the design. Simulation results for a set of ISCAS-89 benchmark circuits and the advanced-encryption-standard IP core show that high levels of security can be achieved at less than 5% area and power overhead under delay constraint.

Xpipes: a network-on-chip architecture for gigascale systems-on-chip

Abstract: The growing complexity of embedded multiprocessor architectures for digital media processing will soon require highly scalable communication infrastructures. Packet switched networks-on-chip (NoC) have been proposed to support the trend for systems-on-chip integration. In this paper, an advanced NoC architecture, called Xpipes, targeting high performance and reliable communication for on-chip multi-processors is introduced. It consists of a library of soft macros (switches, network interfaces and links) that are design-time composable and tunable so that domain-specific heterogeneous architectures can be instantiated and synthesized. Links can be pipelined with a flexible number of stages to decouple link throughput from its length and to get arbitrary topologies. Moreover, a tool called XpipesCompiler, which automatically instantiates a customized NoC from the library of soft network components, is used in this paper to test the Xpipes-based synthesis flow for domain-specific communication architectures.
