Future generations of quantum computers are expected to operate in a paradigm where multi-qubit devices will predominantly perform circuits to support quantum error correction. Highly integrated cryogenic electronics are a key enabling technology to support the control of the large numbers of physical qubits that will be required in this fault-tolerant, error-corrected regime. Here, we describe our perspectives on cryoelectronics-driven qubit control architectures, and will then describe an implementation of a scalable, low-power, cryogenic qubit state controller that includes a domain-specific processor and a SSB upconversion I/Q-mixer-based RF AWG. We will also describe an FPGA-based emulation platform that is able to closely reproduce the system intention, and which was used to verify different aspects of the ASIC system design in in situ transmon qubit control experiments.

Drawing on neuroscience, we have developed a parallel, event-driven kernel for neurosynaptic computation, that is efficient with respect to computation, memory, and communication. Building on the previously demonstrated highly optimized software expression of the kernel, here, we demonstrate True North, a co-designed silicon expression of the kernel. True North achieves five orders of magnitude reduction in energy to-solution and two orders of magnitude speedup in time-to solution, when running computer vision applications and complex recurrent neural network simulations. Breaking path with the von Neumann architecture, True North is a 4,096 core, 1 million neuron, and 256 million synapse brain-inspired neurosynaptic processor, that consumes 65mW of power running at real-time and delivers performance of 46 Giga-Synaptic OPS/Watt. We demonstrate seamless tiling of True North chips into arrays, forming a foundation for cortex-like scalability. True North's unprecedented time-to-solution, energy-to-solution, size, scalability, and performance combined with the underlying flexibility of the kernel enable a broad range of cognitive applications.

Modern FPGAs' parallel computing capability and their ability to be reconfigured make them an ideal platform to build accelerators for supercomputing systems. As a multi-core processor, the recently announced Cell Broadband EngineTM1 offers tremendous computing power. In this paper, we introduce a prototype system that combines these two types of computing devices together in a reconfigurable blade and we describe its architecture, memory system and abundant interfaces. On the reconfigurable blade it is desirable that the FPGA devices can be partially reconfigured at run-time. This paper presents the dynamic partial reconfiguration (DPR) technique and its design flow for the reconfigurable blade. We report our experimental results of the blade doing partial reconfiguration. DPR allows the reconfigurable blade to be a powerful, run-time changeable computing engine. A sample application is presented that was both simulated for the Cell processor and dynamically loaded to run on the FPGA.
