PCI Interrupt Controller for Industry Standard PCI-ISA Bus Architecture using PCI-to-PCI Bridge Technology
نویسنده
چکیده
The demand for more Peripheral Computer Interconnect (PCI) device configurations beyond the limit set in the PCI local bus specification has prompted the development of several PCI-PCI bridge solutions. This paper describes a new PCI Industrial Computer Manufacturers Group (PICMG) PCI-ISA bus architecture implementation using Digital Equipment Corporation PCI-PCI bridge technology. Layered PCI bus architectures, PCI interrupt latency implications and performance optimizations for PCI-PCI bridge designs are discussed. Reference will be made to Digital's family of 64-bit Alpha Single Board Computers (SBCs) and PCI-ISA backplanes which have been specifically designed to address multiple, low cost, high performance PCI requirements associated with high speed communications and graphics in embedded applications.

The AlphaServer 2100 I/O Subsystem
The AlphaServer 2100 I/O subsystem contains a dual-level I/O structure that includes the high-powered PCI local bus and the widely used EISA bus. The PCI bus is connected to the server's multiprocessing system bus through the custom-designed bridge chip. The EISA bus supports eight general-purpose EISA/ISA connectors, providing connections to plug-in, industry-standard options. Data rate isolat...
متن کاملNew I/O Technologies Seek to End Bottlenecks
Computer N ew processors, hard drives, memory chips, networking standards, and other technologies are pushing the limits of computer capabilities. However, the improved performance these developments promise for PCs, servers, and even embedded systems is being choked at a bottleneck caused by input/ output technology, which has failed to keep pace. For example, said Peter Glaskowsky, analyst wi...
متن کاملApplication of bus emulation techniques to the design of a PCI/MC68000 bridge
Bridges easy the interconnection and communication of devices that operate using different buses. In fact, we can see a computer as a hierarchy of buses to which devices are connected. In this paper we design a PCI/MC68000 bridge in order to improve communications between a Personal Computer and a MC68000 based system. The previous interface between both devices was based on the old 16-bit ISA ...
متن کاملUnderstanding PCI Bus, PCI-Express and In finiBand Architecture
There is some confusion in the market place concerning the replacement of the PCI Bus (Peripheral Components Interface) by either the InfiniBandSM Architecture (IBA), PCI-Express (formerly 3GIO Third Generation I/O), or upgrades to the PCI bus itself. Initially the InfiniBand architecture was viewed as the replacement for the PCI bus, yet the PCISIG (PCI Special Interest Group) recently announc...
