Abstract
The present invention provides a computer motherboard having an Intel P54C compatible processor socket and a control chip having specifically arranged data pins and address pins which allows a short signal path arrangement from the processor socket to a cache tap RAM and a cache data RAM. The computer motherboard comprises a four-layer printed circuit board, a processor socket, a cache data RAM, a cache tag RAM, and a control chip. All these components are connected by using a high-order-bit data bus, a low-order-bit data bus, and an address bus through the top and bottom layers of the circuit board. The cache data RAM is positioned on the right side of the processor socket. The control chip is positioned on the top side of the cache data RAM and on the top-right side of the processor socket. It comprises an address section positioned at a bottom-middle portion of the control chip, a high-order-bit data section positioned at a bottom-right corner of the control chip, and a low-order-bit data section positioned at a bottom-left corner of the control chip. The cache tag RAM is positioned between the processor socket and the cache data RAM.
