Title:
SEMICONDUCTOR DEVICE AND METHOD FOR TRANSFERRING DATA
Document Type and Number:
Japanese Patent JP2011035826
Kind Code:
A
Abstract:
To execute asynchronous data transfer in a general purpose way among a plurality of clock domains.
A semiconductor device includes a first clock domain 10 as a data-transfer source, a second clock domain 20 as a data-transfer destination, and data replacing circuits 40, 21, 22 and 23 replacing first data DATA in the first clock domain with second data D3 in the second clock domain. The data replacing circuit contains a first logic circuit 23 for directly comparing the first data DATA with the second data D3 and outputting a first control signal EN.
