Abstract: A sensing device can detect material depth, liquid-level, and temperature. The sensing device has a probe, a control module, a volume sensing module, a thermal sensing module, an output module, and a power module. The probe has two material electrodes connected to the volume sensing module and a thermal electrode connected to the thermal sensing module. A rated voltage is applied at the material electrodes based on radio frequency admittance. A current deviation of the material electrodes is obtained by the volume sensing module, and calculated via the control module by material characteristics to obtain a correct storage amount of material. A temperature at each material depth is correctly detected by the thermal electrode. Steel cable is used as the material of the material electrodes of the probe to detect material depth or liquid level with high impact resistant ability.

Abstract: An external memory based FIFO (xFIFO) apparatus coupled to an external memory and a register bus is disclosed. The xFIFO apparatus includes an xFIFO engine, a wDMA engine, an rDMA engine, a first virtual FIFO, and a second virtual FIFO. The xFIFO engine receives a FIFO command from the register bus and generates a writing DMA command and a reading DMA command. The wDMA engine receives the writing DMA command from the xFIFO engine and forwards an incoming data to the external memory. The rDMA engine receives the reading DMA command from the xFIFO engine and pre-fetches a FIFO data from the external memory. The wDMA engine and the rDMA engine synchronize with each other via the first virtual FIFO and the second virtual FIFO.

Abstract: A forced lock-step operation between a CPU (software) and the hardware is eliminated by unburdening the CPU from monitoring the hardware until it is finished with its task. This is done by providing a data/control message queue into which the CPU writes combined data/control messages and places an End tag into the queue when finished. The hardware checks the content of the message queue and starts decoding the incoming data. The hardware processes the data read from the message queue and the processed data is then written back into the message queue for use by the software. The hardware raises an interrupt signal to the CPU when reaching the End tag. Speed differences between hardware and software can be compensated for by changing the depth of the queue.
