Abstract
Official abstract text for this publication.
A data access system and a data access method achieving effects of power saving and access synchronization during data access are provided. The data access system includes a data processing unit, a bridge device and a memory device. The data processing unit sends an access request signal to initiate data access of at least one unit data. The access of unit data is completed within a plurality of clock cycles of a reference clock signal. The bridge device generates an access signal according to the access request signal, the reference clock signal and a leading time. A pulse of the access signal is determined by the leading time within the clock cycles. The memory device executes the access of the unit data according to the access signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A data access system for generating an access signal to a memory device wherein the memory device comprises registers having flip-flops for storing data stored in the memory device, the memory device executing an access of a unit data according to the access signal, comprising: a data processing unit, activating an access request signal to initiate an access of the unit data, wherein the access of the unit data is executed within a plurality of clock cycles…
