A microcomputer system memory architecture and method allows the system memory to provide data access at high speeds in a burst mode. The architecture and method utilizes a system memory controller capable of performing the addressing of the system memory. The microprocessor and the system memory communicate via a high speed host bus. The system memory is comprised of multiple 64-bit system memory buses to permit high speed data transfer to the microprocessor in a burst mode without the need for an external cache.

System and method for accessing data between a host bus and a system memory bus where the system memory bus has a data path that is twice the width of the data path for the host bus

System and method for accessing data between a host bus and system

A microcomputer architecture and method allows for high processing speeds. A microprocessor constitutes the central processing unit. The microprocessor comprises an on-chip cache memory and is capable of reading data in a burst mode. The central processing unit and the system memory communicate by way of a high speed host bus. The system memory is comprised of multiple buses and is capable of delivering data to the microprocessor in a burst mode at high speeds. A memory controller addresses data locations within the system memory upon receipt of a first host address from the microprocessor. Accordingly, the microprocessor can access data in the system memory at an extremely fast rate when operating in a burst mode. High speed processing is accomplished without the need for an external cache.
