INTRODUCTION

REVIEW

This chapter has provided a basic intro- duction to the 8088 CPU and iAPX 88 systems.

The 8088's pipelined architecture efficiently uses the available bus time to maximize CPU performance and make it possible to get increased performance, even with slower memory devices.

The 8088's register set makes a large number of 16-bit registers available and some registers have special functions allowing more efficient instruction encoding for compact programs.

The 8088's addressing modes provide quick access to complex data structures.

The 8088's instruction set includes powerful 16-bit instructions that lead to smaller pro- grams because many 8088 instructions replace multiple instruction sequences in other 8-bit machines.

The smaller 8088 programs run faster.

With the 8088, it is possible to build lower- cost systems than with other 8-bit micro- processors because the 8088 requires less code memory and runs at high performance with less expensive memories than other 8-bit machines.

Interfacing the 8088 to 8-bit systems is easy with processor extension chips that further increase the 8088's performance through parallel processing using specialized 110 and numeric instructions and registers.

The 8088 is a unique CPU with optimal combination of performance, ease of use, and system economy that meets the needs of sys- tem designers in the 1980's.

The following chapters describe iAPX 88 software, hardware, and system design in more detail.
