66 Appendix B: Technical reference
Summary
Motherboard
• Intel Core i5-7442EQ processor. This processor is designed to accelerate
multimedia and imaging applications, using streaming SIMD extensions (SSE,
SSE2, SSE3, and SSSE4), and EM64T (Intel 64 architecture) technology.
Intel
Quick Sync Video (QSV) technology is also available, which can be used with the
Matrox Imaging Library (MIL) to significantly accelerate image conversion,
compression, and decompression.
• Intel Platform Controller Hub (PCH) HM175 Express chipset (combined
northbridge and southbridge).
• Processor has level 1 (L1), level 2 (L2), and level 3 (L3) caches:
- Level 1 cache: eight 32-Kbyte, non-blocking cache per core (separated into four
groups of 32-Kbyte data cache and four groups of 32-Kbyte instruction cache).
- Level 2 cache: four 256-Kbyte, non-blocking caches per core.
- Level 3 cache: one 6-Mbyte shared, non-blocking cache with virtualization
technology.
• 2 260-pin SO-DIMM (dual channel) slots, each of which supports one
non-removable, unbuffered DDR4 SDRAM SO-DIMM module, up to
16 Gbytes in size.
Warning The SO-DIMM modules are factory installed and should not be modified by the
user because of their location.
• 6 Gigabit LAN controllers (10/100/1000 Mbits/sec). 4 of the Gigabit Ethernet
interfaces support Power Over Ethernet (PoE) and are labeled on the unit.
• 6 USB connectors. 4 of the USB connectors are USB 3.0 and 2 are USB 2.0.
• 2 serial ports (one for RS-232 and one for either RS-232 or RS-485).
