Pipelining processes in a RF reader
First Claim
Patent Images
1. A Radio Frequency (RF) device for pipelining process, comprising:
- a receiver module configured to receive a reply from a transponder in response to an initial command;
a demodulator configured to demodulate the transponder reply and determine preliminary metrics indicative of errors in the transponder reply during demodulation;
a Media Access Control (MAC) engine configured to determine, based on the preliminary metrics, content of and initiate transmission of a subsequent command to the transponder prior to completing demodulation of the reply and, in response to completing demodulation of the reply, either updating the subsequent command signal or terminating transmission of the subsequent command;
a modulator configured to modulate a signal with commands; and
a transmitter module configured to transmit signals to the transponder.

Abstract
The present disclosure includes a method and system for pipelining processes in an RF reader. In some implementations, a method includes receiving, from a transponder, a reply to an initial command. A physical (PHY) layer and a media control access (MAC) layer are pipelined to initiate transmission of a subsequent command during demodulation of the transponder reply.

11. A method for managing transmissions, comprising:
-
receiving, from a transponder, a transponder reply to an initial command; pipelining a physical (PHY) layer and a media control access (MAC) layer to initiate transmission of a subsequent command during demodulation of the transponder reply; and in response to completing demodulation of the transponder reply, either updating the subsequent command or terminating transmission of the subsequent command. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
