Abstract
A data control method in a microprocessor is disclosed. According to the method, a request is generated on an external bus for data to be read to the processor. The requested data is read from the external bus to an intermediate memory in the processor and, thereafter, read from the intermediate memory to a destination. When the intermediate memory is full, the read of data from the external bus is stalled until the intermediate memory is no longer full. Typically, stalling is accomplished by generating a stall signal on the external bus, which may be generated during a cache coherency phase of the transaction to which the requested data relates.
