., LVDS SERDES reverse channel • Proxy Access • A type of I2C device access • Original requestor is aware of 1722 • Requestor will generate packets directly – Initiator Agent implemented in software • Remote bus would have a 1722 Target Agent • Target Agent could be software driving an I2C bus master interface • Transactions are atomic – target bus is left in idle state at end of transaction • Better performance than Transparent Access • Can coexist with Transparent Access Transparent Access • M1 and M2 are I2C masters • IA1 and IA2 are 1722 Initiator Agents • TA is a 1722 Target Agent • A, B, C, and D are end stations (masters or targets) M1 IA1A TA DC M2 IA2B Transparent Access • 1722 Requests originate from Initiator Agent • Breaks down I2C transaction into segments: • Start Write - generate START, ADDR, WRITE, return ACK • Continue Write - generate DATA, return ACK • End Write - generate STOP • Start Read - generate START/RESTART, ADDR, READ, return ACK, DATA • Continue Read - generate ACK, return DATA • End Read - generate NACK, STOP • Request includes: • Segment Type • Bus ID – for multi-initiator arbitration • Maximum completion time – milliseconds • ADDR, DATA • Each request will generate a response • Provides a way to rate limit the requests Transparent Access (cont) • Response includes: • Response type • Success/failure of associated request • State of Target Agent • Response data from Read Request • Extended status upon Status Request or request failure • Failure code: • None • Bus busy timeout – transaction was unable to start in allocated time • Stall timeout – transaction did not complete in allocated time • Initiator conflict– Target Agent busy servicing another initiator’s request • Sequence error – Continue or End with incorrect or missing Start • Address error – Continue or End address not matching Start address • Bus busy time – reports how long the bus had been busy • Competing initiator – bus ID of the initiator agent currently being serviced • Segment count – request segments processed for this I2C transaction, mod 4 • Agent busy – Target Agent was busy processing Transparent Access Requests • Bus ID – Bus ID of the client that the Target Agent is currently servicing Transparent Use Cases • LVDS extender emulation • Only two buses being bridged • Target bus can have local bus masters, but not allowed to access 1722 channel • Target Agent required to maintain retry buffer if local master supported • Multi-Bus • Masters on multiple I2C busses accessing a single target bus • Target Agent locked while busy servicing a request sequence • Target Agent may reject requests while busy with another initiator • Target Agent could provide additional queue to eliminate need to reject new requests while busy • Rejected Initiator Agent will need to retry request • This should be rare – only during initialization or error handling/recovery?
