Aimed at hardware and software designers, this book is a practical guide to the PCI Bus found in every modem PC. The guide begins with an overview of key PCI Bus concepts, including commands, read-and-write transfers, memory and I/O addressing, error handling, and interrupts. It then goes on to more advanced topics, such as PCI-to-PCI bridge architecture and the PCI BIOS. (One possible design application for the PCI Bus is for developing an interface card for controlling a robot from a PC.)The accompanying CD-ROM includes a free, fully searchable eBook version of the text. In addition, a Web site for the book (www.pcidemystified) covers new PCI developments, offers supplemental materials, and provides a reader's forum.Poptronics
