Data path

When a signal reaches a T junction it splits into two copies of itself, one copy traveling along each path. Whenever a 7-0 signal reaches the end of its data path, the path is extended by one site.

The Zoran 38000 has an internal data path of 20 bits as well as a 20 bit address bus. The two accumulators have 48 bits. It can perform a Dolby AC-3 [Vernon, 1995] five channel decoder in real time, although the memory space is also limited to one Megaword. It has a small (16 instruction) loop buffer as well as a single instruction repeat. The instruction set has support for block floating point as well as providing simultaneous add and subtract for FFT butterfly computation. 

The frequency of this sampling is defined in samples per second. Most A/D boards can sample at about 30,000 points/sec, while an HPLC signal requires sampling at no more than 10 points/sec. The other controlling variable is the size of the output digital number. A typical A/D board can only process a number up to 65,000 to process the full range of detector outputs, at least a 12-bit board is required and many boards use a 16-bit data path that allows a word size that can handle numbers up to 1 million.

The Advanced Flexible Processor is a unique and powerful architecture providing an extremely high degree of flexibility and cost-effectiveness. It consists of 16 relatively autonomous functional units interconnected by a power 16 x 18 port, crossbar interconnect. Each of the data paths interconnected by the crossbar is 16 bits wide Table 1 describes the functional unit breakdown of the Advanced Flexible Processor. A conceptualized functional organization of the AFP is shown in Figure 4. 

This deviation is derived from the isothermal-isobaric form of the Gibbs-Duhem equation and can be applied to isobaric equilibrium data by minimizing the composition and temperature differences between pairs of points. This was done by choosing data paths through the ternary equilibrium diagram so that differences in composition and temperature between pairs of points were minimized. A point was considered to be inconsistent if it deviated more than 0.02 with both of its neighbors. This deviation was chosen since it approached the approximate limit of the deviation caused by analytical inaccuracy. Runs 1, 4, 5, 13, 15, 23, 27, and 28 were determined to be inconsistent on this basis. 

Intel introduced the 80386 in 1985. With 275,000 transistors, the 80386 represented a new generation for processors, because it was the first Intel x86 processor that used both a 32-bit data bus and a 32-bit address bus. The situation with the 386 was unique because up until this point Intel would license its technology to other manufacturers. As we mentioned earlier, with the 386 Intel decided to stop licensing. Not to be outdone, the other manufacturers like AMD and Cyrix came up with a chip they called the 386SX. This chip still operated internally at 32 bits (just like the full-blown 386) but had only a 16-bit external data path and a 16-bit address bus. In order to compete on the same ground, Intel then renamed its 386 to the 386DX and introduced its own version of the 386SX with similar specifications.

B. While the 386DX was the first Intel processor to use a 32-bit data bus and a 32-bit address bus, the 486DX was the first Intel processor that used both a 32-bit internal and a 32-bit external data path. 

There were several new, desirable features introduced with EISA. Its creators took the best of MCA s features and added to them. As we have already mentioned, EISA has a 32-bit data path. Additionally, it has more FO addresses, it allows expansion cards to be set up using software, there is no need for interrupts or DMA channels, and it allows for multiple bus-mastering devices. However, despite all these advances, it still uses the 8MHz clock speed of ISA (to ensure backward compatibility with ISA cards). 

PCI has many benefits over other bus types. First, it supports both 64-bit and 32-bit data paths, so it can be used in both 486 and Pentium-based systems. In addition, it is processor independent. The bus communicates with a special bridge circuit that communicates with both the CPU and the bus. This has the benefit of making the bus an almost universal one. PCI buses can be found in PCs, Mac OS-based computers, and RISC computers. The same expansion card will work for all of them you just need a different configuration program for each. 

EISA Acronym for Extended Industry Standard Architecture. A PC bus standard that extends the traditional AT-bus to 32 bits and allows more than one processor to share the bus. EISA has a 32-bit data path and, at a bus speed of 8MHz, can achieve a maximum throughput of 33 megabytes per second. 

Pentium Pro The 32-bit Pentium Pro (also known as the P6) has a 64-bit data path between the processor and cache and is capable of running at clock speeds up to 200MHz. Unlike the Pentium, the Pentium Pro has its secondary cache built into the CPU itself, rather than on the motherboard, meaning that it accesses cache at internal speed, not bus speed.

C. Peripheral Component Interconnect (PCI) is a bus type commonly used with Pentium class computers. This bus type supports 64- and 32-bit data paths and can be used in 486 and Pentium-class computers. See Chapter 5 for more information.
