    摘要： A pipelined processor is provided with a plurality of control stages controlling a datapath made up of a plurality of parallel static-type data latches. The latches each include a feedback circuit, typically a field-effect transistor, which is enabled by a data latch control signal from a particular control stage. Enabling the feedback stage consumes power. A data stagnation detection circuit detects a data stagnation in the datapath, by use of handshake control signals exchanged between the control stages. The data stagnation detection circuit inhibits enablement of the feedback circuit when no data stagnation is detected, reducing power used in the latch.

    摘要： In a data flow machine, a program stored in advance is read out based on a tag included in a packet when the packet including first data is inputted from an external portion. Then, an instruction packet is formed by the content read out as a new tag and the first data, so that the instruction packet is outputted. Second data including the same tag as that included in the first data of the instruction packet read out from the program memory is detected. Firing processing is performed with respect to the first data and the second data as a pair and arithmetic processing is performed according to the instruction as a part of the tag included in an arithmetic packet, so that the arithmetic packet is outputted as a packet. The tag included in the packet is determined and the packet is outputted to an external portion or is inputted again to the internal portion.

    摘要： A data-driven type computer system including an input limiting section for monitoring a current number of packets existing in the circular pipeline of the system while being processed. The input limiting section is adapted to control packets from being inputted from the external unit when the current number of packets exceeds a specified threshold value which is greater than a minimum packet number existing in the circular pipeline and which allows the attainment of the highest possible throughput of the system. The input limiting section further includes a predictive control unit to preliminarily analyze a current data flow graph to be processed in the system and also to take order in rank a possible rate of increase in the quantity of packets generated by a copying operation as well as a possible rate of reduction in the prior processing by the system. While being stored once for buffering by an input buffer, variation in the current quantity of deposited packets is predicted by the predictive control unit every time when packets are entered from an external source or from the output section, so that they are prevented from being entered by the input limiting section when the current quantity of deposited packets is in excess of the preset limit of the hardware.
