Abstract: Some embodiments concern a method of detecting usage of one or more electrical devices coupled to an electrical power line. An electrical power signal with a predetermined period is on the electrical power line. The one or more electrical devices place one or more noise signals on the electrical power line. The electrical power signal comprises the one or more noise signals. The method can include: using a data acquisition device to acquire first data about the electrical power signal on the electrical power line such that the acquiring of the first data is synchronized with the predetermined period of the electrical power signal; processing the first data to create frequency domain data; and applying a feature extraction algorithm to the frequency domain data to determine a transition of an electrical state of at least a first one of the one or more electrical devices.

Abstract: A shared counter resource, such as a register, is disclosed in the hardware, where the register representing how much free space there is in the command queue is accessible to one or more processing elements. When a processing element reads the “reservation” register, the hardware automatically decrements the available free space by a preconfigured amount (e.g., 1) and returns the value of the free space immediately prior to the read/reservation. If the read returns 0 (or a number less than the preconfigured amount), there was insufficient free space to satisfy the request. In the event there was insufficient space to satisfy the request the reservation register may be configured to reserve however much space was available or to not reserve any space at all. Any number of processing elements may read these registers and various scenarios are described where the input and output queues are accessible via various processing elements.

Abstract: A serial input processing apparatus provides how to capture serial data without loss of a single bit while command interpretation is being performed in a command decoder at high frequency. Individual bytes of serial bits of a pre-defined sequence are latched and bit streams are temporarily stored with multiple clocks. The temporary store is conducted before transferring byte information to assigned address registers to register the address. The address registration and the data registration are performed by latching all bit streams of the serial input at the leading edges of clocks. While at a high frequency operation (e.g., 1 GHz or 1 ns cycle time), no additional registers are required for storing bit data during command interpretation with enough time margins between the command bit stream interpretation and next bit data stream.

Further, in start-up processing, the restarted setting value operation service operates the setting value of the operation target application according to the setting information.
