GC <Garbage collection>
Alias:
garbage collection
Field:
OS > Technology > GC
Programming > Java > GC |
The memory management of OS functional one. Gathering the memory territory of the opening which is the memory territory and during programming the program stops using, the technology which increases the available memory territory which it continues. This as for imperfect OS because available memory decreases gradually, it means to be able to force restart every fixed period. Execution environment of Java language (JVM) itself has garbage collection function, the Java programmer does not use the air in memory management and also the [te] that has tried is good.

gcc
Reading: Gee cc
Full spelling: GNU Compiler Collection
Field:
OS > UNIX > GNU > gcc
|
The free compiler by GNU project. It is transplanted in most UNIX affiliation OS. Because at the beginning C language and C++ language were supported, it was called but because it reaches the point where various languages are supported, in name it was modified.

GDDR
Reading: Gee D D earl
Full spelling: Graphics DDR
Field:
Semiconductor > memory > RAM > GDDR |
Standard of the DDR memory which is designed especially as private RAM in order to load onto the video card. Clock frequency is high in comparison with the usual DDR memory which is used in main memory, the fact that also the calorific value is small held down is feature. In addition in order at the little number of clocks at a stroke read-out to be able to write in the device has designated the data which in of memory continues as the address space of memory,
it was retained it is necessary to read and write the picture image data which is continued very frequently in VRAM. In addition, in order 3D it indicates and to calculate, the necessity to be able to access the buffer in VRAM at high speed. Furthermore sticking to the AGP slot and the like of the motherboard, in order to use, heat dissipation, excessively cannot either be difficult to do the video card load the big heat dissipation fan from spatial restriction. The fact that it is designed because this kind of important matter is satisfied especially is GDDR |

GDDR2
Reading: Gee D D earl two
Full spelling: Graphics DDR2
Field:
Semiconductor > memory > RAM > GDDR2
Personal computer > extended card > GDDR2 |
Standard of the DDR memory which is designed especially as private RAM in order to load onto the video card. It is something where GDDR clock frequency it improved, improved the access speed to the data, electric power consumption held down small. There is the DDR2 SDRAM standard and compatibility for general DRAM. GDDR2 largest CAS [reitenshi] 5, maximum operating frequency 800MHz, has become voltage 2.5V outside maximum and maximum signal voltage 1.8V.

GDDR3
Reading: Gee D D earl three
Full spelling: Graphics DDR3
Field:
Semiconductor > memory > RAM > GDDR3
Personal computer > extended card > GDDR3 |
|
Standard of the DDR memory which is designed especially as private RAM in order to load onto the video card. It is something which GDDR (GDDR1), the clock frequency of GDDR2 improves, furthermore improves the access speed to the data. There is the DDR2 SDRAM standard and compatibility for general DRAM. GDDR3 largest CAS [reitenshi] 9, |
