MX46 U2 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. ATA/133 Compared to traditional ATA/100, ATA/133 has been up to 33 percent increase in interface speed with transfer rate of 133MB/s.
MX46 U2 Online Manual CNR (Communication and Networking Riser) The CNR specification provides the PC industry the opportunity to deliver a flexible and cost reduced method of implementing LAN, home networking, DSL, USB, wireless, audio and modem subsystems widely used in today's "connected PCs". The CNR specification is an open industry specification and is supported by OEMs, IHV card manufacturers, silicon supplier and Microsoft.
MX46 U2 Online Manual DMA (Direct Memory Access) Channel for communications between the memory and surrounding devices. ECC (Error Checking and Correction) 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.
MX46 U2 Online Manual EV6 Bus 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. FCC DoC (Declaration of Conformity) The DoC is component certification standard of FCC EMI regulations.
MX46 U2 Online Manual FSB (Front Side Bus) Clock FSB Clock means CPU external bus clock. CPU internal clock = CPU FSB Clock x CPU Clock Ratio I2C Bus See SMBus. IEEE 1394 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.
MX46 U2 Online Manual Parity Bit 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. PBSRAM (Pipelined Burst SRAM) For Socket 7 CPU, one burst data read requires four QWord (Quad-word, 4x16 = 64 bits).
MX46 U2 Online Manual PC-1600, PC-2100 or PC-2700 DDR DRAM Based on FSB frequency, the DDR DRAM has 200MHz, 266MHz and 333MHz three types of working frequency. Because DDR DRAM data bus is 64-bit, it provides data transfer bandwidth up to 200x64/8=1600MB/s, 266x64/8=2100MB/s and 333x64/8=2700MB/s in these current three DDR DRAM. Therefore, the PC-1600 DDR DRAM is working with 100MHz, PC-2100 DDR DRAM is working with 133MHz and PC-2700 with 166MHz FSB frequency.

RDRAM (Rambus DRAM) 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.
MX46 U2 Online Manual SIMM (Single In Line Memory Module) 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. SMBus (System Management Bus) SMBus is also called I2C bus. It is a two-wire bus developed for component communication (especially for semiconductor IC).
MX46 U2 Online Manual Ultra DMA 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.
MX46 U2 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.
