Patent GB-2219659-A (GB)
Title: Loadcells
Inventor: MERRICK ANDREW
IPC: G01G3/145
Filed: 1988-06-09
Abstract: An AC exciter 16, 18, 20 for a loadcell 22 is constructed to provide an excitation waveform which pauses at a substantially zero value for a period of time sufficient for rectifier means 28 in the loadcell signal path to operate, such that small phase shifts have no effect upon the rectified loadcell signal, which therefore has negligible drift due to the electronic circuitry. The loadcell signal is supplied to an integrating A/D converter 42, 44, 46, 48 in which a reference signal is pulse-width modulated at 44 to equalise and balance the weight signal, both supplied to integrator 42. The cycle time of the pulse width modulation is synchronised with the loadcell excitation supply and the time ratio is measured by counting clock pulses until balance is achieved. The pulse width modulation is maintained after equalisation until the next clock pulse has been counted, thereby to accumulate an imbalance in the integrator 42 until equalisation occurs one clock pulse early. The over and under value counts are stored and averaged to provide a measuring resolution of less than one clock pulse per excitation cycle. <IMAGE>

Title: Self configuring cache for microprocessor
Inventor: YARKONI ERAN
IPC: G06F12/08
Filed: 1991-06-04
Abstract: A cache memory 10 and a cache controller 20 therefor are formed on a single substrate. A plurality of identical cache memories may be used in an array. The memories themselves determine how many other memories are in the array and each of their relative positions in the array. From this information, each memory sets the range of its set fields and the size of its tag fields. This is done on reset with the configuration information being distributed among the memories themselves, without being centrally stored, and in a manner transparent to the software. The memory controller 20 receives a configuration signal on a terminal 21, a reset signal on a terminal 22, and a timing signal on a terminal 23, and receives and provides a ready signal on a terminal 24. Upon receiving the reset signal, the configuration signal is sensed and, if it is in a first state, ready signals are counted under the control of the timing signal. If the configuration signal is in a second state the configuration signal is sensed again under the control of the timing signal. <IMAGE>
