Device and method for managing access requests

A device having access request management capabilities, the device comprises:

• a master component, a slave component, a master bus coupled to the master component, a pipelined slave bus coupled to the slave component;
• an access controller adapted to:
• (i) receive, from the master component access requests to access the slave component over the pipelined slave bus;
• (ii) acknowledge 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
• (iii) provide information from the slave component, in response to at least one acknowledged access request.
