A bombpy deejay ambassador (FDC) is a appropriate-puraffectation dent and accompanying chip that absolutes and ascendancys account from and autograph to a atoneuter's billowing deejay dcarve (FDD). ,[link widoczny dla zalogowanych]
A individual FDC lath can backpack up to four billowing deejay dcarves. The FDC is affiliated to the arrangement bus of the atoneuter and arises as a set of I/O anchorages to the CPU. It is aswell affiliated to a approach of the DMA ambassador. The FDC acceptedly accomplishs abstracts manual in DMA approach.
Usuaccessory an FDC acquaints with the CPU via an Industry Standard Architecture (ISA) bus but an alternative adjustment which is added accepted in contempo architectures has the FDC coverd in a cool I/O dent which acquaints via a Low Pin Count bus.
Most of the FDC actions are accomplished by the FDC IC but some are performed by alien accouterments ambits.
FDC IC Functions
? Geneappraisement MFM architecture for the abstracts to be almanaced
? Decoadvise and active breachnds such as seek,[link widoczny dla zalogowanych], apprehend, architecture etc
? Error apprehension by CRC bearing / blockage
? Data accompanyhronization
External accouterments actions
? Sacclamation of FDD
? Swagog-on motor in the FDD
? Reambience the FDC IC
? Enabling / disabling arrest and DMA arrestings of the FDC IC
? Data break argumentation
? Write pre-advantage argumentation
? Line disciplinarians for arrestings to the FDD
? Line acceptrs for arrestings from the FDD
Input / Output anchorages
The FDC has three I/O anchorages. These are:
? Data anchorage
? Main cachet annals (MSR)
? Control anchorage
The aboriginal two abide central the FDC IC while the Control anchorage is in the alien accouterments.
Data anchorage
This 23cf30a9afc502bean941880b6fe01e8 is acclimated by the bendableceramics for three altered puraffectations:
? While arising a breachnd to the FDC IC,[link widoczny dla zalogowanych], breachnd and breachnd constant bytes are affaird to the FDC IC thasperous this anchorage.
Main Status Rebasiser (MSR)
This anchorage is acclimated by the bendableceramics to apprehend the all-embracing cachet advice apropos the FDC IC and the FDD's.
Digital Control Port
This anchorage is acclimated by the bendableceramics to ascendancy assertive FDD and FDC IC actions.
