Controller configured to control timing of access request according to density of burst access and access load

摘要

A controller as an embodiment of the present disclosure controls a timing of transmitting an access request that has been received from an initiator (or its transmission interval). The controller includes: transmitting and receiving circuitry configured to receive an access request related to burst accesses from a first initiator that is connected via a first bus to, and adjacent to, the transmitting and receiving circuitry and configured to transmit the access request to a second bus implemented as a network; and a transmission interval controller configured to control the timing of transmitting the access request that has been received from the first initiator according to density of the burst accesses during a period in which the burst accesses continue and an access load on the second bus.

1. A controller which controls a timing of transmitting an access request that has been received from an initiator, the controller comprising:
transmitting and receiving circuitry configured to receive an access request related to burst accesses from a first initiator that is connected via a first bus to, and adjacent to, the transmitting and receiving circuitry and configured to transmit the access request to a second bus implemented as a network; and a transmission interval controller configured to control the timing of transmitting the access request that has been received from the first initiator according to density of the burst accesses during a period in which the burst accesses continue and an access load on the second bus, said density of the burst accesses determined from the equationTbNp*Tp, where Tb is one burst period in which the burst accesses are generated, Np is the number of times of accesses generated within a single burst period, and Tp is number of cyles to transfer a single packet.
