CPU Execution Cor

PU Execution Coreeee
The 32-bit CPU core is 100% compatible with the MIPS32 instruction
set architecture (ISA). Specifically, this device features the 4Kc CPU
core developed by MIPS Technologies Inc. (www.mips.com). This core
issues a single instruction per cycle, includes a five stage pipeline and is
optimized for applications that require integer arithmetic.
The CPU core includes 8 KB instruction and 8 KB data caches. Both
caches are 4-way set associative and can be locked on a per line basis,
which allows the programmer control over this precious on-chip memory
resource. The core also features a memory management unit (MMU).
The CPU core also incorporates an enhanced joint test access group
(EJTAG) interface that is used to interface to in-circuit emulator tools,
providing access to internal registers and enabling the part to be
controlled externally, simplifying the system debug process.
The use of this core allows IDT's customers to leverage the broad
range of software and development tools available for the MIPS archi-
tecture, including operating systems, compilers, and in-circuit emula-
tors.
PCI Interface
The PCI interface on the RC32434 is compatible with version 2.2 of
the PCI specification. An on-chip arbiter supports up to six external bus
masters, supporting both fixed priority and rotating priority arbitration
schemes. The part can support both satellite and host PCI configura-
tions, enabling the RC32434 to act as a slave controller for a PCI add-in
card application or as the primary PCI controller in the system. The PCI
interface can be operated synchronously or asynchronously to the other
I/O interfaces on the RC32434 device.
Ethernet Interface
The RC32434 has one Ethernet Channel supporting 10Mbps and
100Mbps speeds to provide a standard media independent interface
(MII or RMII), allowing a wide range of external devices to be connected
efficiently.
Double Data Rate Memory Controller
The RC32434 incorporates a high performance double data rate
(DDR) memory controller which supports x16 memory configurations up
to 256MB. This module provides all of the signals required to interface
to discrete memory devices, including a chip select, differential clocking
outputs and data strobes.

The RC32434 uses a dedicated local memory/IO controller including
a de-multiplexed 8-bit data and 26-bit address bus. It includes all of the
signals required to interface directly to a maximum of four Intel or
Motorola-style external peripherals.
