摘要:
A heterogeneous array includes clusters of processing elements. The clusters include a combination of ALUs and multiplexers linked by direct connections and various general-purpose routing networks. The multiplexers are controlled by the ALUs in the same cluster, or alternatively by ALUs in other clusters, via a special purpose routing network. Components of applications configured onto the array are selectively implemented in either multiplexers or ALUs, as determined by the relative efficiency of implementing the component in one or the other type of processing element, and by the relative availability of the processing element types. Multiplexer control signals are generated from combinations of ALU status signals, and optionally routed to control multiplexers in different clusters.
摘要:
A high resolution Fourier Transform Ion Cyclotron Resonance (FT-ICR) mass spectrometry system includes excitation circuitry including an excitation amplifier for generating an electrical excitation signal and excitation electrodes for applying an oscillating electric field to excite ions in the system. Detection circuitry including detection electrodes measures a detection signal which includes a plurality of signal values including signal values induced by the ions. Structure is provided for reducing or canceling coupling of the excitation signal into the detection signal, wherein simultaneous excitation and detection is used. A computing structure generates a Fourier transformed frequency domain representation of the detection signal and deconvolves the frequency domain representation using complex division to separate a dispersion spectrum portion and an absorption spectrum portion.

Leakage currents across circuit components such as transistors are avoided by placing circuits into a low-leakage standby mode. The circuits are configured such that voltage differentials across leakage-prone circuit components are avoided when in standby mode. Various means are used to configure the circuits, such as configuration ports, data input lines, scan chains, etc. In embodiments containing reconfigurable devices, low-threshold transistors are used to implement the routing network.

A field programmable device comprising an array of processing devices, a connection matrix interconnecting the processing devices and including switches, and memory cells for storing data for controlling the switches to define the configuration of the interconnections of the connection matrix. In order to provide flexible use of memory and to enable higher memory densities, gates are provided which can be used to isolate the effect of the data stored in groups of the memory cells and switches on the configuration of the interconnections so that the memory cells in that group are available for storing other data.

摘要:
A ring oscillator comprises a first logic block having a first input connected to a specific point along a delay path, a first output and a second output and a second logic block having a first input connected to the first output of the first logic block, a second input connected to the second output of the first logic block, a third input connected to the end of the delay path and a first output connected to the beginning of the delay path. The first logic block is arranged to, in use, alternately switch its first output and second output from logical HIGH to logical LOW, and vice versa, every time a rising edge is input into its first input. The second logic block is arranged to, in use, alternately select its first input and its second input every time a rising edge is input into its third input. The pulse width of the signal output from the first output of the second logic block is indicative of the time necessary for one of a rising edge or a falling edge to propagate from the beginning of the delay path to the specific point along the delay path and the inverse pulse width of the signal output from the first output of the second logic block is indicative of the time necessary for the one of the rising edge or the falling edge respectively to propagate from specific point along the delay path to the end of the delay path.
