A closed form design method for recursive 3-D cone filters

A closed form design method for recursive 3-D cone filters is presented. The filters are realized by concrete passive 3-D wave digital filter (WDF) structures leading to the associated desirable properties of multidimensional WDF. The proposed method is accomplished analytically without the need for time consuming numerical optimization techniques. In contrast to previously reported methods, which are based on cascading 2-D or 3-D fan or wedge shaped filters the proposed method establishes nonseparable transfer functions which offer an excellent approximation to the required circular symmetry.<<ETX>>

The receiver engine chip-set for digital audio broadcasting

The described DAB (digital audio broadcasting) receiver system, consisting of the analogue front-end and the digital baseband IC D-FIRE, offers the most compact receiver design available in the market today. Furthermore, the power consumption of the complete system is lass than 2 Watt in total for fullstream decoding, i.e., 1.7 Mbit/s. This paper describes the first true VLSI single chip solution for DAB. The D-FIRE (DAB-fully integrated receiver engine) is a 7 Mio. transistor chip fabricated in LSI logic 0.35 /spl mu/m process. Due to the on-chip ADC, RAM and audio decoder, no additional hardware is required for audio only applications. Extended with a 2 Mbit SRAM the maximum data-rate of 1.7 Mbit/s can be decoded while the system can dynamically follow a multiplex reconfiguration. This paper describes the architecture, some technical solutions and the features of the DAB receiver engine chip-set.

Wave digital filters for the migration of seismic data

A closed form design method for migration wave digital filters (MWDF) is presented. Migration filters are 2-D fan shaped filters with a prescribed nonlinear phase in the passband. An analytical solution is presented which solves simultaneously the approximation problems for attenuation and phase. The attenuation is approximated in a maximally flat sense in pass- and stopband. The phase of the ideal migration filter is approximated in a way which is equivalent to the approximation of the wave equation by the McClellan transform. Efficient WDF structures, including a multiplier-free scheme, for the realization of MWDF are derived.<<ETX>>

A design methodology for high performance ICs: wireless broadband radio baseband case study

In this paper, we provide an overview of the hardware-software design flow that has been applied to the design of a platform based SoC for the HiperLAN/2 and IEEE 802.11a wideband wireless communication standards. Starting from a high-level description in MATLAB, the design framework is used to gain important information for the HW/SW partitioning. Step by step the MATLAB description is refined down to an embedded assembler implementation. Simultaneously, the framework is used to generate cycle true reference data for simulations on several abstraction levels. A universal interface concept allows the exchange of modules of different abstraction levels in a cosimulation. This way, a high confidence level for the design verification is achieved, and design and verification time is substantially reduced.

Early level 4/5 automation by restriction of the use-case

Automated Driving (AD) has significantly evolved during the last years. Starting with DARPA’s Grand Challenge in 2004 and 2005, as well as the Urban Challenge in 2007 with a clear focus on university research, we see today first AD systems on the market. Even more are being announced, both by traditional automotive OEMs as well as by startups and IT companies that have never built cars before.

The connected car and its implication to the automotive chip roadmap

The automotive industry is in a radical change process driven by technology. On the one hand side the proliferation of communication technologies into the car leads to internet connected vehicles. The vehicle will become an integral part of the internet — opening new processing paradigms for the car itself. On the other hand the vehicle itself significantly expands its sensor and processing capabilities by the use of radar, video, ultrasound sensors and usage of state of the art CPU and GPU processor architectures. In our talk we will address both developments and outline foreseen future applications as future driving assistant and infotainment systems as well as highly automated driving. We will discuss major requirements for the future electrical architectures and implications for future automotive chips.
