Utility
Function evaluation using multiple values loaded into registers by a single instruction
23 May 23
A technique for efficient calling of functions on a processor generates an executable program having a function call by analysing an interface for the function that defines an argument expression and an internal value used solely within the function, and an argument declaration defining an argument value to be provided to the function when the program is run.

Utility
Intelligent power saving
11 Apr 23
A device comprising: a transceiver operable in a first or second mode and configured to receive packets from a remote device, each packet comprising an indication of whether or not the remote device has a further packet to transmit, wherein: in the first mode the transceiver: (i) sends a polling message in response to receiving the indication of a further packet for transmission; and (ii) listens for that further packet; and in the second mode the transceiver: (i) does not send a polling message in response to receiving the indication of a further packet for transmission; and (ii) listens for packets regardless of whether a received packet indicates that there is a further packet to transmit or not; and a controller configured to monitor an activity level for the transceiver and cause the transceiver to operate in the first or second mode in dependence on the activity level.
