Current trends show, it is increasingly difficult to manage the constraints of costs, power consumption, size and more than everything else, functional safety, with conventional architectures. This paper presents a new architecture to deal with the current and upcoming requirements in safety critical applications. It proposes the use of diverse redundancy with digital and analog channels, to detect random hardware failures as well as systematic failures. That will increase the functional safety. By exploiting the ability of dynamic and partial hardware reconfiguration of FPGA and FPAA and by using the appropriate failure recovery scenario, the system availability can also be increased. Furthermore, the architecture offers the possibility to combine high accuracy with short response time.

Analog circuits and systems research and education can benefit from the flexibility provided by large-scale Field Programmable Analog Arrays (FPAAs). This paper presents the hardware and software infrastructure supporting the use of a family of floating-gate based FPAAs being developed at Georgia Tech. This infrastructure is compact and portable and provides the user with a comprehensive set of tools for custom analog circuit design and implementation. The infrastructure includes the FPAA IC, discrete ADC, DAC and amplifier ICs, a 32-Bit ARM based microcontroller for interfacing the FPAA with the user's computer, and Matlab and targeting software. The FPAA hardware communicates with Matlab over a USB connection. The USB connection also provides the hardware's power. The software tools include three major systems: a Matlab Simulink FPAA program, a SPICE to FPAA compiler called GRASPER, and a visualization tool called RAT. The hardware consists of two custom PCB designs which include a main board used to program and control an FPAA IC and an FPAA IC adaptor board used to interface a QFP packaged FPAA IC with the 100 pin ZIF socket on the main programming and control board.

“…This second-order section is used in the Gm-C filters. The FPAA provides 500-fF capacitors and programmable offset wide linear range OTAs [8]. In this circuit, V in is the input node; for a high-pass filter, V out HP is taken to be the output; for a low-pass filter, V out LP is taken to be the output.…”

Psychoacoustic bass enhancement system on reconfigurable analog signal processor

Because of size and cost constraints, small loudspeakers are used in many applications. It is very difficult to have a good low-frequency response in these small speakers. To produce good-sounding bass, we use psychoacoustic techniques to enhance deep bass in small loudspeakers-hence "extending" the bandwidth of auditory signals. This system is implemented in the analog domain, demonstrating the efficient signal processing capability of low power analog circuits. The bass enhancement system is designed, programmed, and tested on a floating-gate based field programmable analog array (FPAA), a reconfigurable analog signal processor. Measurements from a working prototype are presented. We can transfer the analog system developed on the FPAA to custom IC designs, or use the FPAA as the final implementation platform.
