COM Express module’s got game

Mar 31, 2010 — by Eric Brown — from the LinuxDevices Archive — 6 views

Avalue is shipping a COM Express Computer-on-Module (COM) aimed at gaming machines. The ESM-GM45 supports Intel Core 2 Duo or Celeron M processors, is equipped with an Intel GM45 chipset, supports up to 4GB DDR2 memory, and offers interfaces including gigabit Ethernet, SATA, USB 2.0, PCI, and PCI Express, says the company.

Designed for gaming machines, such as slot machines, video games, or multi-player games, the ESM-GM45 gets its name from the Intel GM45 graphics chipset. The GM45 is accompanied by an ICH9-M controller, and the module offers a socket that supports either an Intel Core 2 Duo or Celeron M processor, says Avalue. The COM supports up to 4GB DDR2 667/800Mhz SDRAM via dual 200-pin SODIMMs, says the company.

The GM45 can drive dual monitors in various combinations, while enabling dual-channel 18/24-bit LVDS for resolutions up to UXGA (1600 x 1200), says Avalue. Intel High-Definition Audio is also said to be available.

Storage support includes four SATA interfaces, while expansion is provided via four PCI, four PCI-Express (PCIe) x1, and one PCIe x16 slots, says the company. A gigabit Ethernet controller is said to be included, as well as eight USB 2.0 interfaces, LPC, SMbus/I2C, and eight GPIOs.
