摘要： In a bus resource having an outbound pipe for processing both non-posted and posted transactions in a FIFO manner, a rejected non-posted transaction at the head of the outbound pipe is moved aside and into an auxiliary buffer to avoid a potential blockage of the outbound pipe. The auxiliary buffer is for holding transaction information and return data of the rejected non-posted transaction. The rejected transaction is eventually completed from the auxiliary buffer as determined by an arbiter.

摘要： A slave device having clock rate compensation circuitry for low frequency operation. The slave device is coupled to a bus having a first operating frequency yet uses a slave clock signal having a frequency less than the first operating frequency. The slave device includes a bus clock driver circuit coupled to a bus clock interface for a bus clock signal. A slave controller state machine is clocked by the slave clock signal and accordingly operates at less than the first operating frequency. The clock rate compensation circuitry receives the bus clock signal, a data signal, and the slave clock signal, and synchronizes bus events for the state machine. The clock rate compensation circuitry also asynchronously begins a bus clock signal stretching period.

摘要： A method and apparatus for open loop buffer allocation. In one embodiment, the method includes loading requested data within a buffer according to a load rate. Concurrent with the loading of data within the buffer, the data is forwarded from the buffer according to drain rate. In situations where the load rate exceeds the drain rate, read requests may be throttled according to an approximate buffer capacity level to prohibit buffer overflow. In one embodiment, a rate for issuing data requests, for example, to memory, is regulated according to a predetermined buffer accumulation rate. Accordingly, in one embodiment, the open loop allocation scheme reduces latency while enabling sustained read streaming with a minimal size read buffer. Other embodiments are described and claimed.

摘要： An arbiter comprising logic circuitry configured to delay granting bus ownership to an agent X in response to receiving a first signal which indicates that a device coupled to the bus is not available to service transactions directed at the device over the bus. For instance, the device may be a bridge and the grant is delayed if an inbound pipe of the bridge is full. The arbiter may provide a borrowed grant to an outbound pipe of the device for performing a transaction on the bus while waiting for an inbound pipe of the device to become available.
