摘要： This invention relates to a layout structure for providing stable power supply to a four-layer motherboard and a main bridge chip substrate. In the invention, on the top signal layer and power path of the bottom solder layer for layout of the main bridge chip and on the power ring, the decoupling capacitors are connected in between the ground bonding pads/solder balls and the power bonding pads/solder balls of the power paths and power rings, so as to provide a stable power supply for the operation of the main bridge chip.

摘要： An integrated testing method is proposed to perform a test procedure on a number of computer components, concurrently, in a multitasking manner through software simulation. In this method, an initialization procedure is first performed to specify the total number of simulated operations, the FIFO buffer size, the command sequence, and the start time of operation. It is a characteristic feature of this integrated testing method that the test procedure is performed concurrently in a multitasking manner on all the components under test to operate in response to each command from the command sequence. In the event that two or more of the components under test are competing for the same resource, an arbiter is activated to perform arbitration for these competing components.

摘要： A memory access control method and system is provided for use on a computer system to control the memory access operation by a central processing unit (CPU) to a memory unit in a more efficient manner. This memory access control method and system is characterized in the capability of switching the memory access operation between a waiting mode and a non-waiting mode based on the current L1write-back condition of the read requests from the CPU. In the waiting mode, the memory unit responds to each read request in such a manner as to wait until the L1write-back signal of the read request is issued and then either perform a read operation for the current read request if the L1write-back signal indicates a cache miss, or perform a cache write-back operation if the L1write-back signal indicates a cache hit. In the non-waiting mode, the memory unit responds to each read request in such a manner that it will always promptly perform a read operation for the current read request without waiting until the CPU issues the L1write-back signal of the current read request, and in the event that the subsequently received L1write-back signal of the read request indicates a cache hit, promptly abandon the currently retrieved data from the memory unit and then performing a cache write-back operation.

摘要： A method and the associated devices for implementing a suspend-to-RAM (STR) mode of operation in a computer system utilizing the self-refreshing capability of synchrotron DRAM. To switch into the STR mode of operation, system memory data in a first control chip (the north bridge) is first transferred to a memory unit under the direction of a second control chip (the south bridge). The voltage level at the clock-enable pin of the system memory is pulled down under the direction of the south bridge or the north bridge. Power to the north bridge is cut upon receiving a signal from a basic input/output system.
