Cyrix Cx486DLC

The Cyrix Cx486DLC was an early 486 CPU from Cyrix, intended to compete with the Intel 486SX and DX. Texas Instruments, who manufactured the 486DLC for Cyrix, later released its own version of the chip, the TI486SXL, with 8 kB internal cache vs 1 kB of the original Cyrix design. The similarly named IBM 486DLC, 486DLC2, 486DLC3 (aka Blue Lightning) are often confused with the Cyrix chips, but are not related and are instead based on Intel's i486 design.

Introduced in June 1992, like the later and more famous Cyrix Cx5x86 it was a hybrid CPU, incorporating features of a new CPU (in this case the Intel 80486) while plugging into its predecessor's (386DX) socket. It ran at speeds of 25, 33, and 40 MHz.

The 486DLC can be described as a 386DX with the 486 instruction set and 1 KB of on-board L1 cache added. Because it used the 386DX bus (unlike its 16-bit cousin, the 486SLC) it was a fully 32-bit chip. Like the 386 and 486SX, it had no on-board math coprocessor, but unlike the 486SX, it could make use of an Intel 387DX or compatible numeric coprocessor. A few 486SX motherboards also provided i387 sockets, but this feature was a very much a rarity. Due to the smaller L1 cache, the 486DLC could not compete on a clock-for-clock basis with the 486SX, but a 33 MHz 486DLC could keep pace with a 25 MHz 486SX, cost less, and offered the ability to upgrade further with the addition of an inexpensive math coprocessor.

DLC

DLC may refer to:

DLC1

Deleted in Liver Cancer 1 also known as DLC1 and StAR-related lipid transfer protein 12 (STARD12) is a protein which in humans is encoded by the DLC1 gene.

This gene is deleted in the primary tumor of hepatocellular carcinoma. It maps to 8p22-p21.3, a region frequently deleted in solid tumors. It is suggested that this gene is a candidate tumor suppressor gene for human liver cancer, as well as for prostate, lung, colorectal, and breast cancers.

Gene

The human DLC1 gene is located on the short arm of chromosome 8 (8p21.3-22), within a region that frequently undergoes loss of heterozygosity by either genomic deletion or epigenetic silencing mechanisms in several types of solid cancers. The gene contains 14 exons and produces an mRNA transcript that is 6.3 kb in length; the second AUG present in the open reading frame is the major translational start site, and produces a polypeptide which is 1091 amino acids long.

The promoter region of the DLC1 gene contains a CpG island containing several CpG sites which can be methylated to promote gene silencing and prevent transcription.

SCS

50th Space Communications Squadron

The 50th Space Communications Squadron (50 SCS) is a squadron of the United States Air Force located at Schriever Air Force Base, Colorado. The squadron provides command and control systems, configuration control, and systems integrations for seven Department of Defense space programs including $6.2 billion Air Force Satellite Control Network supporting $50 billion in national satellite and terrestrial systems for United States, allied, and coalition forces.

The squadron operates and maintains 22 Defense Information Systems Agency nodes providing secure and unsecure voice and data communications for over 485 worldwide sites as well as over $100 million in base infrastructure supporting over 8,900 personnel.

The 50 SCS has been operating and maintaining Global Broadcast Service (GBS) since February 2009 and is working on transitioning it to a new Defense Enterprise Computing Center architecture.

50 SCS manages Air Force Space Command's Global Command and Control System.

850th Space Communications Squadron

The 850th Space Communications Squadron (850 SCS) was a component of the 50th Network Operations Group, 50th Space Wing, Schriever Air Force Base, Colorado. The squadron was activated 1 December 1997 as the 850th Communications Squadron and redesignated the 850th Space Communications Squadron on 1 October 2002. It was inactivated on 31 January 2006, most of its functions and personnel having been incorporated into the 50th Space Communications Squadron.

Mission

The mission of the 850th Space Communications Squadron was to plan, integrate, and maintain command and control, and common user communications and computer systems for satellite navigation, communications, missile warning and space surveillance worldwide.

The squadron was responsible for logistics management, systems maintenance, and integrity of satellite command, control, communications, and computer systems for the Air Force Space Command (AFSPC) mission including the $6.2 billion Air Force Satellite Control Network, supporting over 140 Department of Defense satellites. The squadron also provided anomaly resolution, systems integration and configuration control supporting AFSPC, USSTRATCOM, the Secretary of Defense, and the President.
