Title: Cache oblivious algorithm for butterfly code
Inventor: CYRIL GUYOT
IPC: H03M13/13
Filed: 2016-09-16
Abstract: Cache oblivious butterfly encoding algorithm for generating parities and repairing data erasures. A first subset of contents comprising data elements C0[0]-C1[1] is retrieved from memory to stores C0-C1. First parity P1 is updated using the subset by calculating a horizontal parity via XOR-ing data elements in the same row. A second parity P2 is updated though orthogonal permutation of the first subset and first correcting factor C0[0]. P2 comprises combinations of data elements (C1[0] C0[0]) already in the first parity, i.e. likely to be still cached. When second subset C0[2]-C1[3] (704-714) is retrieved, P1-P2 are updated likewise except for the permutation being an inverse orthogonal permutation. This way P2 comprises data elements C1[3] C0[3] (763) as in P1 (754). The addition of first and second correcting factors C0[0] and C0[3] in recursive manner provides more cache hits when calculating the second parity. Butterfly-code is 2-parity maximum-distance-separable (MDS) erasure-code over GF(2).

Title: An apparatus and method for controlling use of bounded pointers
Inventor: Ruben Borisovich Ayrapetyan
IPC: G06F21/52
Filed: 2018-08-20
Abstract: Controlling the use of bounded pointers in an apparatus with memory allocation circuitry by arranging the bounded pointer generation circuitry to generate a revocable bounded pointer to be used to access a memory region. The revocable bounded pointer also provides a pointer and range information that can be used to identify an address range of the memory region 405. It then provides a header for the memory region, where the header has a first token field whose stored value is a first token value associated with the memory region. The memory allocation circuitry responds to a deallocation of the memory by modifying the stored value in the first token field of the header, and in a subsequent response to generate a memory address using the revocable bounded pointer, causes an authentication check that prevents the memory address from being generated 425 if it determines that first token value has been changed 415.

The method may allow a more controlled and cost-effective silicon-silicon carbide coating, particularly for relatively complex carbon components such as degassing rotors. The binder may be styrene acrylate co-polymer. The solvent may be water. A carbon component comprising the silicon-silicon coating and coating compositions for use forming said coating are also provided.

Title: An analogue-to-digital converter (ADC)
Inventor: Anthony Sou
IPC: H03M1/52
Filed: 2019-04-08
Abstract: A dual-slope ADC comprises an integrator, e.g. a capacitor 108, selectively connectable to an input signal current or a reference current by a first switch 102 & 103, a voltage supply 118 selectively connectable to the integrator by a second switch 112 & 120, and a comparator 114 with a first input connected to the integrator, and a second input connected to a threshold voltage 116. The voltage supply is arranged to supply a first voltage to the integrator so as to integrate over a first time period a first current corresponding to one of said reference signal and said analogue signal, and, following the first time period, to provide a second voltage to said integrator from said voltage supply, so as to integrate over a second time period a second current corresponding to the other one of said reference signal and said analogue signal, in order to generate a digital output signal corresponding to said analogue signal. Importantly, the said first current and said second current flow in the same direction during respective said first time period and said second time period. The converter is thus particularly suitable for implementation in a unipolar process, e.g. either NMOS or PMOS.
