The 82437VX System Controller, also known as TVX, is a key component of the Intel 430VX PCIset. It integrates cache and main memory DRAM control functions and provides bus control for transfers between the CPU, cache, main memory, and the PCI Bus. The TVX is designed to support 3V Pentium processors and is PCI 2.1 compliant. It offers a fully synchronous 25/30/33 MHz PCI bus interface and supports up to five PCI bus masters, including PIIX3. The TVX's integrated DRAM controller supports up to 128 MB of main memory with five rows and a variety of DRAM types, including EDO, Fast Page Mode, SDRAM, and more. The controller also supports Shared Memory Buffer Architecture (SMBA) for improved graphics performance. The 82437VX System Controller is available in a 208-pin QFP package.
