Title: Realm identifiers for realms for memory access control
Inventor: GARETH RHYS STOCKWELL
IPC: G06F12/14
Filed: 2017-06-28
Abstract: Memory access circuitry (26, fig 3) enforces ownership rights for memory regions. A given memory region is associated with an owner realm specified from multiple realms, each realm corresponding to a portion of at least one software process executed by processing circuitry (8, fig 1). The owner realm can exclude other realms from accessing data within the memory region. Realm management circuitry (20, fig 3) accesses a realm management tree 160 which may comprise realm descriptor tree granules (RDTG) 162 which each may comprise realm descriptor tree entries (RDTE) 164 storing realm management data. The realms are identified using a realm identifier 168 which has a variable number of variable length bit portions (170, fig 14) each providing an index into a given level of the realm management tree.

Title: Collision-warning system
Inventor: NANJUN LIU
IPC: G08G1/16
Filed: 2017-08-22
Abstract: A collision-warning system for a motor vehicle is provided. The collision-warning system includes a controller (34 in Figure 1) includes a processor and a memory storing processor-executable instructions in a host vehicle 30. The processor 34 is programmed to designate a target vehicle 32 as a collision risk upon determining that an intersection angle β between the host vehicle 30 and the target vehicle 32 is between preset lower and upper bounds and an absolute value of an azimuth angle rate of change dθ/dt of the host vehicle 30 s below a preset threshold. The controller 34 allows the host vehicle 30 to determine whether the target vehicle 32 is a collision risk and, if warranted, perform evasive maneuvers or warn a driver of the collision risk. By relying on the intersection angle β and the azimuth angle rate of change dθ/dt, the controller 34 determines collision risk in a computationally efficient manner with a low amount of error and measurement noise. The computational efficiency may allow more frequent updating and thus more accurate tracking of the target vehicle 32.
