generation
The Tundra Semiconductor Tsi107 PowerPC Host Bridge provides system
interconnect between PowerPC processors, PCI peripherals and local
memory. PCI support allows system designers to design systems quickly using
peripherals already developed for PCI and the other standard interfaces
available in the personal computer hardware environment.
The Tsi107 provides many of the other necessities for embedded
applications, including a high-performance memory controller and dualprocessor support; two-channel flexible DMA controller; an interrupt
controller; an I2O-ready message unit; an inter-integrated circuit controller
(I2C); and low-skew clock drivers. The Tsi107 contains an Embedded
Programmable Interrupt Controller (EPIC) featuring five hardware interrupts
(IRQs), as well as 16 serial interrupts and four timers. The Tsi107 uses an
advanced, 2.5V CMOS process technology, and is fully compatible with TTL
devices.

Multiprocessor and Local Bus Slave Support
The Tsi107 supports a programmable interface to microprocessors
implementing the PowerPC architecture, operating at bus frequencies up to
133 MHz. The Tsi107 processor interface allows for a variety of system
configurations by providing support for a second processor and a local bus
slave.

Package
Host Bridge Application
PCI Bus Support
The Tsi107 PCI interface is designed to connect the processor and memory
buses to the PCI local bus without the need for “glue” logic. It runs at
speeds up to 66 MHz. The Tsi107 acts as either a master or target on the PCI
bus and contains a PCI bus arbitration unit which reduces the need for an
equivalent external unit. This reduces the total system complexity and cost.
Typical Application
The Tsi107 can be used in either a system host configuration or as a
peripheral device. For system applications where cost, space, and power
consumption are critical parameters, the Tsi107 provides a complete solution
without sacrificing performance. The Tsi107 is shown below as a host bridge.
