PCI 9054 PCI Applications High performance Motorola MPC 850/860 PowerQUICC Designs A key application for the PCI 9054 is Motorola MPC 850/860 based adapters for telecom and networking applications. 2 1 PCI 9054 I/O Accelerator PowerQUICC MPC860 IDMA MEM 2 Local Bus DMA 0 DMA 1 ROM PCI Bus Figure 1. High Performance MPC860 PowerQUICC Adapter Design n Supports PCI bus mastering from local slave-only devices n Scatter/Gather list management -Descriptors can be in the PCI or local bus memory -Allows independent scatter/gather ring management These applications include high perfor- mance communications like WAN/LAN controller cards, high speed modem cards, frame relay cards, and networking cards for routers and switches to name a few. The PCI 9054 simplifies designs by pro- viding an industry leading enhanced direct-connect interface to the MPC 850/860 processor. The PCI 9054’s flexi- ble, 3.3V, 5V tolerant I/O buffers com- bined with a local bus operation up to 50MHz is ideally suited for current and future PowerQUICC processors. The PCI 9054 also provides support for the MPC860 IDMA channel for movement of data between internal MPC860 I/O and the PCI bus. In addition, the PCI 9054 also makes use of the advanced Data Pipe Architecture including unlimited burst capability as shown in figure 1. For PowerQUICC IDMA operation, 1 the PCI 9054 transfers data to PCI under the control of the IDMA hand- shake protocol. At the same time, the PCI 9054 Data 2 Pipe Architecture™ DMA can be oper- ated bi-directionally, with the PCI 9054 as the master for both buses, to manage transfers of data from the local bus to the PCI bus or from the PCI bus to the local bus. This is a prime example of how the PCI 9054 provides superior general purpose bus master perfor- mance and gives the designer using the PowerQUICC processor greater flexibility in implementing multiple simultaneous I/O transfers. The PCI 9054 has unlimit- ed bursting capability which enhances any MPC860 PowerQUICC design. High Performance CompactPCI Adapter Designs Another key application for the PCI 9054 is CompactPCI adapters for telecom and networking applications. These applica- tions include high performance commu- nications like WAN/LAN controller cards, high speed modem cards, frame relay cards, and telephony cards for telecom switches and remote access systems. The PCI 9054 has intergrated key features to enable live-insertion of Hot Swap CompactPCI adapters. The PCI 9054 PICMG 2.1 compatible Hot Swap Friendly PCI interface includes both Hot Swap Capable and Friendly features: Hot Swap Capable n PCI specification v2.1 or better n Tolerant of Vcc from early power n Tolerant of asynchronous reset n Tolerant of precharge voltage http://www.elecfans.com 电子发烧友 http://bbs.elecfans.com 电子技术论坛

n Has limited I/O pin leakage at precharge voltage Hot Swap Friendly n Incorporates the Hot Swap Control/Status register (HS_CSR) n Programmable Prefetch Counter-The PCI 9054 can be programmed to prefetch data during PCI Initiator and PCI Target operations. The prefetch size can be programmed to match the master burst length or can be used as Read Ahead I/O Chips (Datacom, Telecom, Storage, etc.) I/O CPU Local Bus RAM ROM PCI Bus PCI 9054 I/O Accelerator Figure 2. High Performance CompactPCI Adapter n Posted Memory Writes-Supports Posted Memory Writes (PMW) for maximum performance and to avoid potential deadlock situations PCI Bus Operation n PCI Dual-Address Cycle (DAC)-Support (64-bit Address Space) enables 64-bit addressing in 64-bit PCI host systems n PCI Power Management-Supports four power states for PCI functions D0, D1, D2, and D3hot and the Power Management Event interrupt (PME#) n New Capabilities Structure-Supports New Capabilities registers to define additional capabilities of PCI functions Local Bus Operation n Programmable Local Bus-Runs up to 50MHz and supports non-multi- plexed 32-bit address/data, multiplexed 32-bit, and slave accesses of 8-, 16-, or 32-bit Local Bus devices. Allows Local Bus bursting up to 200Mbytes/second. n Three PCI-to-Local Address Spaces-The PCI 9054 supports three PCI-to-Local Address spaces when the PCI 9054 is in PCI Target mode. These spaces (Space 0, Space 1, and Expansion ROM spaces) allow any PCI Bus Master to access the local memory spaces with program- mable wait states, bus width, and burst capabilities. Figure 3.

In this configuration, the PCI 9054 Data Pipe Architecture allows high performance transfer modes. In addition, the PCI 9054 supports both Type 0 and Type 1 PCI configuration cycles which allows the PCI 9054 to configure other PCI devices or cards in the system. Additional Features General Purpose Bus Master Operation n Advanced Data Pipe Architecture includes DMA engines, PCI Initiator, PCI Target, and PCI messaging functions. n Dual independently programmable Data Pipe Architecture DMA engines with programmable FIFOs. Each channel supports block and scatter/gather DMA modes. n 5V Tolerant Operation-The PCI 9054 requires 3.3 Vcc. It provides 3.3V signal- ing with 5V I/O tolerance on both the PCI and Local Buses. mode data. The PCI 9054 reads single data (8-, 16-, or 32-bit) if the master initiates a single cycle; otherwise, the PCI 9054 prefetches the programmed size. n Six Programmable FIFOs for concurrent burst transactions n Zero wait state burst operation n Serial EEPROM Interface-Contains an interface for an optional serial EEPROM that can be used to load configuration information. The PCI 9054 can also be configured by a local CPU. n Clock-The Local Bus interface runs from a local TTL clock and asserts the neces- sary internal clocks. This clock runs asynchronously to the PCI clock. n Big/Little Endian Conversion-Supports dynamic switching between Big Endian and Little Endian data for PCI Initiator, PCI Target, DMA, and internal register accesses on the Local Bus n Fully supports the Vital Product Data (VPD) PCI extension-Provides an alternate access method other than Expansion ROM for Vital Product Data n Interrupt Generator- Can assert PCI and local interrupts from external and internal sources http://www.elecfans.com 电子发烧友 http://bbs.elecfans.com 电子技术论坛

The PCI 9054 is supported by a variety of development tools designed to assist the designer in the form of Reference Design Kits (RDK), and Software Design Kits (SDK). These Kits enable designers to quickly bring new designs to production without worrying about the complexities of implementing PCI and I 2O. The PCI 9054 is fully compatible 2O SDK with PLX’s PCI SDK and I software development kits which allow quick and easy development of high per- formance local and host PCI software through standard APIs, I 2O messaging protocols, PCI debug tools, and example drivers. PCI 9054 design support is provided through RDKs which provide a exible PCI development board, complete with Orcad schematics, documentation, and software.
