MX34-U Online Manual G l os s a r y AC97 Basically, AC97 specification separates sound/modem circuit to two parts, digital processor and a CODEC for analogy I/O they are linked by AC97 link bus. Since digital processor can be put into motherboard main chipset, the cost of sound/modem onboard solution can be reduced. A C P I ( A d v a n c e d C o n f i g ur a t i o n & P ow e r I n te r f a c e ) ACPI is the power management specification of PC97 (1997).
MX34-U Online Manual A M R ( A u d i o/ M o d e m R i s e r ) The CODEC circuit of AC97 sound/modem solution can be put on motherboard or put on a riser card (AMR card) that connects to motherboard through AMR connector. A O pe n B o n us P a c k C D A disc bundled with AOpen motherboard product; there are motherboard drivers, Acrobat Reader for PDF online manual and other useful utilities.
MX34-U Online Manual ATA/100 ATA/100 is a new IDE specification under developing. ATA/100 uses both rising edge and falling edge as ATA/66 but clock cycle time is reduced to 40ns. The data transfer rate is (1/40ns) x 2 bytes x 2 = 100MB/s. To use ATA/100, you need special 80-wire IDE cable, the same as ATA/66. B I O S ( Ba s i c I n p u t / O u t p u t S y s t e m ) BIOS is a set of assembly routine/program that reside in EPROM or Flash ROM.
MX34-U Online Manual C O DE C ( C o d i n g a n d De c o di n g ) Normally, CODEC means a circuit that can do digital to analog conversion and also the analog to digital conversion. It is part of AC97 sound/modem solution. D D R ( D o u b l e Da t a R a te d ) S D R A M DDR SDRAM utilizes the existing DRAM infrastructure and technology while doubling the nominal bandwidth available to systems in an easy to design and simple to adopt way.
MX34-U Online Manual E C C ( E r r or C he c k i n g a n d C or r e c t i o n ) The ECC mode needs 8 ECC bits for 64-bit data. Each time memory is accessed; ECC bits are updated and checked by a special algorithm. The ECC algorithm has the ability to detect double-bit error and automatically correct single-bit error while parity mode can only detect single-bit error. E DO ( E x t e n de d Da t a O u t p u t ) M e m or y The EDO DRAM technology is actually very similar to FPM (Fast Page Mode).
MX34-U Online Manual EV 6 B u s EV6 Bus in the technology of Alpha processor from Digital Equipment Corporation. EV6 bus uses both rising and falling clock edge to transfer data, similar as DDR SDRAM or ATA/66 IDE bus. EV6 Bus Speed = CPU external bus clock x 2. For example, 200 MHz EV6 bus is actually using 100 MHz external bus clock, but the equivalent speed is 200 MHz. F C C D o C ( De c l a r a t i o n o f C o n f o r m i ty ) The DoC is component certification standard of FCC EMI regulations.
MX34-U Online Manual F S B ( F r o n t S i d e B u s ) C l oc k FSB Clock means CPU external bus clock. CPU internal clock = CPU FSB Clock x CPU Clock Ratio I2C Bus See SMBus. IE EE 1 39 4 IEEE 1394 is a low-cost digital interface originated by Apple Computer as a desktop LAN and developed by the IEEE 1394 working group. The IEEE 1394 can transport data at 100, 200 or 400 Mbps. One of the solutions to connect digital television devices together at 200 Mbps.
MX34-U Online Manual P a r i t y Bi t The parity mode uses 1 parity bit for each byte, normally it is even parity mode, that is, each time the memory data is updated, parity bit will be adjusted to have even count "1" for each byte. When next time, if memory is read with odd number of "1", the parity error is occurred and this is called single bit error detection. P BS R A M ( P i p e l i n e d B u r s t S R A M ) For Socket 7 CPU, one burst data read requires four QWord (Quad-word, 4x16 = 64 bits).
MX34-U Online Manual P CI ( P e r i ph e r a l C o m p o ne n t I n te r f a c e ) B u s Bus for the internal connection of peripheral devices, high-speed data channel between the computer and expansion card. P D F F o r ma t A file format for electronic document, PDF format is independent from platform, you can read PDF file under Windows, Unix, Linux, Mac … with different PDF reader.
MX34-U Online Manual R D R A M ( R a mb u s D R A M ) Rambus is a memory technology that uses large burst mode data transfer. Theoretically, the data transfer should be high than SDRAM. RDRAM is cascaded in channel operation. For Intel 820, only one RDRAM channel is supported, 16-bit data per channel, and this channel may have maximum 32 RDRAM devices, no matter how many RIMM sockets. R I M M ( Ra m b u s I n l i n e M e m o r y M o d u l e ) 184-pin memory module that supports RDRAM memory technology.
MX34-U Online Manual S I M M ( S i n gl e I n Li n e Me m o r y M o d u l e ) SIMM socket is only 72-pin, and is only single side. The golden finger signals on each side of PCB are identical. That is why it was called Single In Line. SIMM is made by FPM or EDO DRAM and supports 32-bit data. SIMM had been phased out on current motherboard design. S M B us ( S y s te m Ma n a g e m e n t B us ) SMBus is also called I2C bus.
MX34-U Online Manual U l t ra D M A Ultra DMA (or, more accurately, Ultra DMA/33) is a protocol for transferring data between a hard disk drive through the computer’s data path (or bus) to the computer’s random access memory (RAM). The Ultra DMA/33 protocol transfers data in burst mode at a rate of 33.3MB/s, twice as fast as the previous Direct Access Memory (DMA) interface.
MX34-U Online Manual VCM (Virtual Channel Memory) NEC’s Virtual Channel Memory (VCM) is a new DRAM core architecture that dramatically improves the memory system’s ability to service multimedia requirements. VCM increases memory bus efficiency and performance of any DRAM technology by providing a set of fast static registers between the memory core and I/O pins. Using VCM technology results in reduced data access latency and reduced power consumption.
