RISC-V RISC-V International announced four new specification and extension approvals. Efficient Trace for RISC-V defines an approach to processor tracing that uses a branch trace. RISC-V Supervisor Binary Interface architects a firmware layer between the hardware platform and the operating system kernel using an application binary interface in supervisor mode to enable common platform services... » read more

Power/Performance Bits: Jan. 5


Quiet qubits Researchers at the University of New South Wales Sydney recorded the lowest noise levels yet for a semiconductor qubit. Charge noise caused by material imperfections interferes with the information encoded on qubits, reducing accuracy. "The level of charge noise in semiconductor qubits has been a critical obstacle to achieving the accuracy levels we need for large-scale error-c... » read more
