Features
32-bit CPU Core
– MIPS32 instruction set
– Cache Sizes: 16KB instruction and data caches, 4-Way set
associative, cache line locking, non-blocking prefetches
– 16 dual-entry JTLB with variable page sizes
– 3-entry instruction TLB
– 3-entry data TLB
– Max issue rate of one 32x16 multiply per clock
– Max issue rate of one 32x32 multiply every other clock
– CPU control with start, stop and single stepping
– Software breakpoints support
– Hardware breakpoints on virtual addresses
– Enhanced JTAG and ICE Interface that is compatible with v2.5
of the EJTAG Specification
DDR Memory Controller
– Supports up to 2GB of DDR SDRAM
– 2 chip selects (each chip select supports 4 internal DDR
banks)
– Supports 16-bit or 32-bit data bus width using 8, 16, or 32-bit
devices
– Supports 64Mb, 128Mb, 256Mb, 512Mb, and 1Gb DDR
SDRAM devices
– Data bus multiplexing support allows interfacing to standard
DDR DIMMs and SODIMMs
– Automatic refresh generation
Memory and Peripheral Device Controller
– Provides “glueless” interface to standard SRAM, Flash, ROM,
dual-port memory, and peripheral devices
– Demultiplexed address and data buses: 16-bit data bus, 26-bit
address bus, 6 chip selects, supports alternate bus masters,
control for external data bus buffers
– Supports 8-bit and 16-bit width devices
Automatic byte gathering and scattering
– Flexible protocol configuration parameters: programmable
number of wait states (0 to 63), programmable postread/post-
write delay (0 to 31), supports external wait state generation,
supports Intel and Motorola style peripherals
– Write protect capability per chip select
– Programmable bus transaction timer generates warm reset
when counter expires
– Supports up to 64 MB of memory per chip select
Counter/Timers
– Three general purpose 32-bit counter timers
PCI Interface
– 32-bit PCI revision 2.2 compliant (3.3V only)
– Supports host or satellite operation in both master and target
modes
– Support for synchronous and asynchronous operation
– PCI clock supports frequencies from 16 MHz to 66 MHz
– PCI arbiter in Host mode: supports 6 external masters, fixed
priority or round robin arbitration
–I2O “like” PCI Messaging Unit
