Triton definition

Intel's Pentium core logic chip set. In addition to the traditional features, this chip set supports: EDO DRAM to increase the bandwidth of the DRAM interface; "pipelined burst SRAM" for a cheaper, faster second level cache; "bus master IDE" control logic to reduce processor load; a plug and play port for easy implementation of functions such as audio.
The Triton I chipset (official name 82430FX) consists of 4 chips: one 82437FX TSC (Triton Sysetm Controller), two 82438FX TDP (Triton Data Path), and one 82371FB PIIX (PCI IDE Xcellerator). It supports PB Cache, EDO DRAM, and a maximum PCI and memory burst data transfer rate of 100 megabytes per second.
There are also Moble Triton (82430MX), Triton II (82430HX), and the Triton VX (82430VX) chip sets.
