    摘要: The electronic circuit contains a basic delay circuit (14). A delay is realized by activating the same basic delay circuit (14) a plurality of times in response to a single start signal before generating a response to that start signal. A control circuit (12) receives a start signal and an outputs a response. The control circuit (12) causes a series of signals to be passed through the delay circuit (14), the series starting at a time that is time-continuously triggered by the start signal. Each successive signal in the series starts after a preceding signal has emerged from the delay circuit (12) and the series being terminated after a controlled number of more than one signal has been passed. The control circuit (12) supplies the response upon termination of the series. In one embodiment the series is realized by means of a handshake sequencing circuit (120) that generates a series of successive handshake transactions.

    摘要: A locally synchronous circuit module has a delay circuit having and input and output coupled to a clock input. The delay circuit provides a delay which when incorporated in a clock oscillator ensures a clock period that is at least as long as needed to transfer information between the storage elements. A handshake circuit is provided for generating handshake signals for timing information transfer between the locally synchronous circuit module and a further circuit. The handshake circuit comprises the delay circuit, so that at least part of the handshake signals during a handshake transaction are timed by traveling through the delay circuit and are applied to the clock input to clock the locally synchronous circuit module.

    摘要: A data processing apparatus contains several processing circuits each operating under control of its own periodic clock signal, so that the clock signals may have different frequencies and/or can be autonomous. The several processing circuits each have an output for outputting memory access requests, which remain at the output for a validity duration interval defined by the clock signal of the particular processor. A multiplexing circuit multiplexes the access requests to a memory. The memory needs a minimum memory repetition period before it can accept an access request following acceptance of a preceding access request. The clock periods of the processing circuits are longer than the minimum memory repetition period. A timing circuit selects acceptance time points at which each particular access request from a first data processing circuit is accepted.

    摘要: A data processing apparatus contains several processing circuits each operating under control of its own periodic clock signal, so that the clock signals may have different frequencies and/or can be autonomous. The several processing circuits each have an output for outputting memory access requests, which remain at the output for a validity duration interval defined by the clock signal of the particular processor. A multiplexing circuit multiplexes the access requests to a memory. The memory needs a minimum memory repetition period before it can accept an access request following acceptance of a preceding access request. The clock periods of the processing circuits are longer than the minimum memory repetition period. A timing circuit selects acceptance time points at which each particular access request from a first data processing circuit is accepted. The time point at which the particular request is accepted is always within the validity duration interval in which the particular access request is made. The timing circuit varies the position of the acceptance time points within the validity duration intervals, so that the position is delayed to make room for previously accepting an access request from another processor. The position is subsequently moved back toward a start of the validity duration interval in successive steps during application of successive access requests from the first data processing circuit.
