Abstract

A Single-Flux-Quantum (SFQ) 4-bit throughput-oriented processor has successfully been demonstrated at up to 32 GHz with the measured power consumption of 6.5 mW. This is the first implementation of the gate-level-pipelined processor, and it achieves 2.5 Tera-Operations Per Watt (TOPS/W) by circuit and architectural optimizations.

A multiplier based on superconductor single-flux-quantum (SFQ) logic is demonstrated up to 48GHz with the measured power consumption of 5.6 mW. The multiplier performs 8 × 8-bit signed multiplication every clock cycle. The design is based on a bit-parallel, gate-level-pipelined structure that exploits ultimately high-throughput performance of SFQ logic. The test chip fabricated using a 1.0-μm, 9-layer process consists of 20,251 Nb/AlOx/Nb Josephson junctions (JJs). The correctness of operation is verified by on-chip high-speed testing.

A 57.2GHz 11.2mW 8-bit General Purpose Superconductor Microprocessor with Dual-Clocking Scheme

Ikki Nagaoka, Ryota Kashima, Tomoki Nakano +4 more

A superconductor single-flux-quantum (SFQ) logic 8-bit microprocessor is demonstrated up to 57.2 GHz with a measured power consumption of 11.2 mW. The microprocessor has an ultradeep, gate-level pipelining containing many feedback paths and communications between components. The arrival clock timings at all the logic gates are ultra-precisely tuned using two different clocking schemes, called “concurrent-flow” and “counter-flow,” to achieve extremely high clock frequency operation over 50 GHz. Low-temperature circumstances enable us to conduct super delay-intensive layout design by controlling delays of all waveguide interconnects in the order of sub-picosecond precision.

Demonstration of a 52-GHz Bit-Parallel Multiplier Using Low-Voltage Rapid Single-Flux-Quantum Logic

Ikki Nagaoka, Koki Ishida, Masamitsu Tanaka +5 more

A high-throughput 4$\boldsymbol{\times }$4-bit multiplier was demonstrated using an extremely careful timing design for low-voltage rapid single-flux-quantum (LV-RSFQ) logic. The design considers the lengths of all wires, bias dependency of the delays, and load dependency of the signal splitters. The key is to intentionally use both Josephson transmission lines and passive transmission lines for gate-to-gate wiring, even over short distances, to form the same structure wiring as the clock lines. The structure of the multiplier is based on a bit-parallel, gate-level pipeline to exploit throughput. The test chip was fabricated using the AIST 10-kA/cm$\boldsymbol{^2}$, Nb/AlOx/Nb, 9-Nb-layer Advanced Process 2. The measured maximum operating frequency, throughput, and power consumption without cooling cost in the high-speed on-chip test were 52 GHz, 52 G-operations per second (GOPS), and 134$\boldsymbol{\mu }$W, respectively. Although the switching speed of the Josephson junctions was reduced by 40$\boldsymbol{\%}$owing to the low-voltage operation, the obtained clock frequency was as high as that demonstrated with the standard bias voltage. The energy efficiency was 381 tera-operations per second per watt (TOPS/W) at 4.2 K. Further improvement in energy efficiency is expected by using low-voltage half-flux-quantum (LV-HFQ) circuits and shrinking the size of Josephson junctions.

Fei Ke, Olivia Chen, Yanzhi Wang +1 more

A fast Fourier transform (FFT) is an algorithm that computes the discrete Fourier transform (DFT) of a sequence at high speed. FFT can convert a signal from time domain to frequency domain, and is wildly used in digital signal processing field. In this paper, a high-speed, low-power FFT processor is demonstrated up to 47.8GHz with the measured power consumption of 5.3mW, using single-flux quantum (SFQ) logic. This is the first complete FFT processor implementation using superconducting technology, performing 8-point 7-bit FFT in a bit-serial computing manner. The test chip fabricated using a 1.0 μm 9-layer process consists of 17 455 Nb/AlOx/Nb Josephson junctions (JJs), rendering itself the largest superconducting digital circuit capable of iterative data computing. The correct operation of the chip has been experimentally confirmed at a maximum operating frequency of 47.8GHz (word speed 8GHz) by conducting on-chip high-speed testing.

Design and Implementation of a Pipelined Bit-Serial SFQ Microprocessor, ${\rm CORE}1\beta$

Yuki Yamanashi, Masamitsu Tanaka, A. Akimoto +7 more

A pipelined 8-bit-serial single-flux-quantum (SFQ) microprocessor, called CORE1beta, was designed and tested. The CORE1beta has two cascaded arithmetic logic units (ALUs) based on forwarding architecture, which can perform two register operations from one instruction. Pipelining is also extensively adopted to enhance the performance. A new design method, known as one-hot encoding, has been introduced into the design of the control circuit. The 4-stage-pipelined SFQ microprocessors, CORE1beta8, have been implemented using the CONNECT cell library and the SRL 2.5 kA/cm2Nb process. The frequency for the instruction fetch is 25 GHz, and 20 GHz for the bit-serial data operation. The peak performance and the power consumption of the CORE1beta8 are estimated to be 1400 MOPS (million instructions per second) and 3.4 mW, respectively. We have experimentally demonstrated 4-stage pipelining and all functionalities of the CORE1beta8 microprocessors by on-chip high-speed tests.

64-GHz Datapath Demonstration for Bit-Parallel SFQ Microprocessors Based on a Gate-Level-Pipeline Structure

Ryota Kashima, Ikki Nagaoka, Masamitsu Tanaka +2 more

We successfully demonstrated an 8-bit-wide, bit-parallel datapath composed of an arithmetic logic unit and register files for high-throughput oriented SFQ microprocessors based on a gate-level-pipeline structure. Achieving high-speed operation in the bit-parallel datapath is difficult because of feedback paths. We used concurrent-flow clocking and counter-flow clocking in combination to solve the timing problem at the feedback path in the datapath, and we optimized the number of JJs and pipeline stages in the register file for solving the timing issue. We designed the datapath with the cell library for the AIST 10 kA/cm$^2$Advanced Process. The total number of pipeline stages, Josephson junctions, and circuit area of the designed datapath were 52, 18448, and 3.81 mm × 4.05 mm, respectively. We obtained a relatively wide bias margin of the designed datapath at the target clock frequency of 50 GHz, and it operated up to 64 GHz in on-chip high-speed testing.
