Summary and Conclusions
The ARM instruction set is a thoroughly modern, 32-bit RISC instruction set. Unlike the 8086 and 68K processors, all instructions are the same length and, with few, exceptions, execute in one clock cycle. The register set is almost compl[r]

8. Make certain that you and the hardware designers agree on which Endian model you are using.
9. Be judicious in your use of global variables. At the risk of incurring the wrath of Com- puter Scientists I won’t say, “Don’t use global variables” because global[r]

times the number of main memory refill lines as with a direct-mapped cache. At first glance, this may not seem like much of an improvement. However, the key is the associativity of the 4-way design. Even though we have 4 times the number of columns, and 4 possible[r]

A 5 GHz clock rate corresponds to a clock period of 200 picoseconds (ps). Since the speed of light is roughly 12 inches per nanosecond in free space and 6 inches per nanosecond through a wire, this means that in 200 ps, light can travel about 1.2 inches. A modern microprocesso[r]

In some applications we actually might choose not to take advantage of the multiple data transfer instructions, even though they improve code density. Suppose that an interrupt comes into the processor for an external device that is extremely time-critical. It must be serviced as soon as po[r]

This group of instructions is rather involved in that they have different rules depending upon how many positions the bits are shifted and whether the effective address is a register or memory. How- ever, shift and rotate instructions are very important as part of the ov[r]

Don’t be overwhelmed by the number of opcodes and operands that are part of the 68K, or any processor’s ISA. The real point here is that you can write fairly reasonable programs using just a subset of the possible instructions and addressing modes. Don’t be overw[r]

In order to reinforce the concept of the storage register as a unique circuit element instead of a collection of D-flops, we can redraw Figure 4.17 as shown in Figure 4.18.
Earlier in this chapter, we’ve repeatedly referred to the “state” of a flip-flop. By that we were[r]

Monitoring of toxic gas in air is important because air pollution, especially in developing countries, has rapidly become severe. The high cost of installation and maintenance of a stationary analysis system by using methods such as gas chromatography limits its applications.

The most important type of network that employs the CSMA/CD is called ethernet.
Ethernet was originally a proprietary LAN standard (predating the IEEE 802.3 standard) developed by the Xerox corporation of USA. The original design was based on a length
