Abstract
A peripheral controller device (14) controlling at least a first peripheral device (16) attached thereto, the controller device including a programmable and selectable buffer memory for utilization with a first type and a second type of write instruction for writing data to first type (24) and a second type (26), respectively, of memory in the peripheral device (16). The peripheral controller device includes an n deep buffer memory (36), where n is an integer greater than one, for buffering the write instructions. A user may programmably indicate whether only the first type of write instruction is to be buffered or both types of instructions are to be buffered. Responsive to such programming, write instructions are examined to determine if they are of the first type or the second type. Depending on the programming, write instructions of the second type are routed to the buffer or are routed by bypassing the buffer memory.
