Preliminary Data Sheet
OPB
The OPB provides 32-bit address and data interfaces, and operates up to 100MHz. There are bridges between the
OPB and the PLB.
Features include:
Pipelined read support
Dynamic bus sizing
Single-cycle data transfer between masters and slaves
DCR Bus
The daisy-chained DCR bus provides a path for passing status and control information between the processor core
and the other on-chip cores. All DCRs are 32 bits in width with 10-bit addressing.
External Bus Controller
The external bus controller (EBC and EBM ) transfers data between the PLB and external memory or peripheral
devices attached to the external peripheral bus. The EBC provides direct attachment of memory devices such as
ROM and SRAM, DMA device paced memory devices, and DMA peripheral devices.
Features include:
From 60MHz to 100 MHz speed
Data bus is 8, 16, or 32 bits with a 27-bit address bus
Up to four chip selects
Arbitration and multi-master supported
Flash ROM interface
Boot from EBC (including NAND Flash interface) support
Direct support for 8-,16-, or 32-bit SRAM and external peripherals
External bus master support
NAND Flash Controller
The NAND Flash controller (NDFC) provides a simple interface between the External Bus Controller (EBC) and a
variety of NAND Flash-based storage devices.
Attachment as internal EBC slave device
Eight- and 16-bit NAND Flash interface
Up to four banks of NAND Flash supported
Device sizes of 4MB to 256MB (32Mb to 2Gb) supported
512B + 16B or 2kB + 64B device page sizes supported
ECC generation - hamming code, single-bit correction, double-bit detection (SEC/DED)
Eight-bit command write, address write, and data read/write
Interrupt on device ready (after long page write or block erase operations)
Boot from NAND
– Executes up to 4KB of boot code out of first block
– Automatic page read accesses performed based on device configuration and read address
DMA Controller
The Direct Memory Access (DMA) controller is a Processor Local Bus (PLB) master that enables faster data
transfer between memory and peripherals than is possible under program control. The 4-channel DMA controller
handles data transfers between memory and peripherals and from memory-to-memory. Each channel has an
independent set of registers needed for data transfer: a control register, a source address register, a destination
address register, and a transfer count register.
