Abstract
A device and a method for managing access requests, the method includes: (i) receiving, from a master component coupled to a master bus, multiple access requests to access a slave component over a pipelined slave bus; acknowledging a received access request if: (a) at least an inter-access request delay period lapsed from a last acknowledgement of an access request; (b) an amount of pending acknowledged access requests is below a threshold; wherein the threshold is determined in response to a pipeline depth of the pipelined slave bus; (c) the received access request is valid; wherein a validity of an access request is responsive to a reception of an access request cancellation request; and (ii) providing information from the slave component, in response to at least one acknowledged access request.
