    摘要: A memory controller and method of operation for detecting different type of dynamic random access memory (DRAM) devices in a computer system. The memory controller has capabilities for improved page hits which cause the row address strobe signals to remain asserted following certain cycles. A mechanism in the memory controller selectably disables column address strobing. Different DRAM types are distinguishable by reading back data previously written to a memory location. Data is written to memory with a cycle causing the memory controller to keep the row address strobes asserted. Column address strobing is disabled. A read back cycle is performed without column address strobing. If data is present, the DRAM is an extended data output (EDO) DRAM. If data is not present, the DRAM is a fast page mode DRAM.

    摘要: A computer system provides a self-modifying synchronization memory address space and protocol for communication between multiple busmasters. In one computer system embodiment, the self-modifying synchronization memory address space is provided in a memory controller embedded in a peripheral device of the computer system such as a bridge that provides central, high speed access by a busmaster to the memory controller without accessing a host bus. The synchronization memory address space includes a set of semaphore memory cells mapped to shared critical resources in the computer system. The semaphore memory cell allows for exclusive access by a busmaster to a shared critical resource by switching itself from an idle state to a busy state responsive to a first read operation by a busmaster. In the busy state of the semaphore memory cell, a busy state is communicated to other busmasters which attempt to read the semaphore memory cell. Ownership of the semaphore memory cell is thus achieved using a single operation by a busmaster. The properties of the self-modifying synchronization memory address space and the semaphore memory cell thus eliminate the need for assertion of a bus locking signal to achieve exclusive access for a busmaster to a shared critical resource. These properties also eliminate the need for host processor intervention in accessing a shared critical resource when a busmaster is a PCI master.

    摘要: A switching circuit controls the routing of various signals of the computer system to and from the various pins of a microprocessor socket. A microprocessor rests in the socket and can be removed and replaced by another microprocessor. Variations in the pin arrangements of the two processors can be compensated for by appropriately setting the switches on the processor card. The use of 486SX, 487SX and 486DX microprocessors is illustrated in a single socket.
