Publication number: 20240086542Abstract: In various examples there is a computing device comprising: a first microcontroller comprising a first immutable bootloader and first mutable firmware. The first immutable bootloader uses a unique device secret burnt into hardware of the computing device in order to generate an attestation of the first mutable firmware. The computing device has a second microcontroller. There is second mutable firmware at the second microcontroller. There is a second immutable bootloader at the second microcontroller which sends a measurement of the second mutable firmware to the first immutable bootloader whenever the second microcontroller restarts, such that the first microcontroller is able to include the measurement in the attestation.Type: ApplicationFiled: November 13, 2023Publication date: March 14, 2024Inventors: Stavros VOLOS, Colin DOAK, Simon Douglas CHAMBERS, David RUGGLES, Richard NEAL, Cedric Alain Marie FOURNET, Kapil VASWANI, Balaji VEMBU

Patent number: 11625061Abstract: Two clocks, a fast clock and a slow clock are provided for clocking a processing unit. A plurality of frequency settings, referred to as gears, are defined for the two clock. Each of these gears indicates a maximum frequency for the fast clock and a minimum frequency for the slow clock, such that the gap between the two frequencies may be kept to a manageable level so as to reduce transients upon switching between the two clocks. The system switches between the gears as required. In response to a determination to increase the frequency of the clock signal, a higher gear is selected at which the maximum and minimum frequencies defined for that gear are higher than the previous selected gear.Type: GrantFiled: June 16, 2021Date of Patent: April 11, 2023Assignee: GRAPHCORE LIMITEDInventors: Simon Douglas Chambers, Stephen Felix, Ian Malcolm King
