Handshake synchronization system

Abstract: A method and apparatus for improving the performance of the transferring of transaction handshakes between sections of synchronous logic which are in different timing domains providing immunity from set-up and hold violations and associated problems of metastability, by reducing the time overhead required for signal synchronization.

Asynchronous bus interface for generating individual handshake signal for each data transfer based on associated propagation delay within a transaction

Abstract: A method and apparatus is provided for use in an asynchronous bus interface capable of multiple or single width transfers and controlled by handshake signals, in which the bus transaction may include multiple successive data transfers delineated by a data strobe, and in which each data transfer is terminated by a data handshake signal, and in which data transfers for different cycle types incur different propagation delays, including bus buffering apparatus for directing transfers over single and multiple width busses, and an asynchronous bus controller for returning data handshake signals with individualized timing characteristics in response to the master data strobe and the cycle type of the transaction, such that each successive data transfer is completed in the minimum time that propagation delays, as indicated by the cycle type, will allow, in order to maximize bus throughput

The Handshake as Non‐verbal Communication in Business

Abstract: The first thing you do when you meet someone in a business context is to tell that person who you think you are, who you think they are, and what you think the nature of your relationship is going to be. Explores some of the issues which surround the handshake in a business setting and discusses some of the characteristics and meanings of handshakes, with special attention to gender and cultural differences. The argument is made that, if there is a problem in the workplace for uninitiated, untrained persons with handshaking, it would be worthwhile addressing communication skill in an educational setting.

Asynchronous circuit for 2-cycle to 4-cycle handshake conversion

Abstract: A two- to four-cycle handshake protocol conversion circuit suitable for on-chip implementation uses an exclusive-OR Gate and an AND Gate with one inverted input together with a latching circuit to generate the two-cycle handshake protocol acknowledge signal, A2, as a clocked version of the two-cycle handshake protocol request signal, R2, using the rising edge of the four-cycle handshake protocol acknowledge signal, A4, as the clocking input. The four-cycle handshake protocol request signal R4 is provided as the ANDed output of the complement of A4 combined with the output of the exclusive-OR Gate, the inputs of which are provided by R2 and A2. The latching network may be provided by a simple D flip-flop.

Two self-timed handshake controllers for high speed applications

Abstract: Self-timed circuits with an appropriate handshake control circuit (HCC) can be used to replace the global clock in a VLSI chip. The authors focus on designing a handshake controller with the highest frequency possible. The gain in speed results from the handshake protocol allowing certain constraints. The approaches taken in the two protocols, and the implementation, characteristics and constraints are discussed. The HCCs were rigorously tested by applying them to a bit-serial multiplier based on the modified Booth's algorithm. Some results on the delay measurements of the HCCs and simulation results of the multipliers are presented. >

Handshake system between host computer and tool

Abstract: PURPOSE:To surely secure the handshake between a host computer of a semidouble communication system and a tool which performs the multi-task processing by shortening the time-out period of the host computer compared with that of the tool CONSTITUTION:A host computer 1 has its time-out setting time shorter than that of a tool 2 In other words, the time-out period (trs) of the tool 2 is longer enough than the time-out period (trq) of the computer 1 Thus the computer a never starts its time-out operation nor proceeds to its time-out processing before the response is returned from the tool 2 against the transmission of the response In this case, however, the tool 2 does not receive the request sent from the computer 1 owing to the discontinuation of its time-out processing and receives only the response returned from the computer 1 Thus the handshake is recovered between the computer 1 and the tool 2

Method and apparatus for efficient serialized transmission of handshake signal on a digital bus

Abstract: An asynchronous handshake signal (111,151) is encoded in order to facilitate the transfer of the asynchronous handshake signal (111,151) from a first network segment (10) to a second network segment (30). On the first network segment (10), control signals and data signals are encoded as control symbols (122,125,128,130,132,135,138,140) and data symbols (123,127,129,133,134,137,139), respectively. The control symbols (122,125,128,130,132,135,138,140) and the data symbols (123,127,129,133,134,137,139) are transferred from the first network segment (10) to the second network segment (30) across an interconnection medium (41,42). In order to send a handshake signal (111,151) from the first network segment (10) to the second network segment (30), the handshake signal (111,151) on the first network segment (10) is sampled. When the handshake signal (111,151) on the first network segment (10) is at a first signal level, a control symbol (122,125,128) of encoded control signals is sent across the interconnection medium (41,42). When the handshake signal (111,151) on the first network segment (10) is at a second signal level, a data symbol (123,127,129) of encoded data signals is sent across the interconnection medium (41,42).
