About This Manual
This document describes the operation of the DDR2 Memory Controller in the TMS320C6452.
Notational Conventions
This document uses the following conventions.
•
Hexadecimal numbers are shown with the suffix h. For example, the following number is 40
hexadecimal (decimal 64): 40h.
•
Registers in this document are shown in figures and described in tables.
–
Each register figure shows a rectangle divided into fields that represent the fields of the register.
Each field is labeled with its bit name, its beginning and ending bit numbers above, and its
read/write properties below. A legend explains the notation used for the properties.
–
Reserved bits in a register figure designate a bit that is used for future device expansion.
Note:
Acronyms 3PSW, CPSW, CPSW_3G, and 3pGSw are interchangeable and all refer to the 3
port gigabit switch.

Data Manual—
— TMS320C6452 Digital Signal Processor Data Manual describes the signals, specifications
and electrical characteristics of the device.
CPU—
— TMS320C64x/C64x+ DSP CPU and Instruction Set Reference Guide describes the CPU
architecture, pipeline, instruction set, and interrupts for the TMS320C64x and TMS320C64x+ digital
signal processors (DSPs) of the TMS320C6000 DSP family. The C64x/C64x+ DSP generation
comprises fixed-point devices in the C6000 DSP platform. The C64x+ DSP is an enhancement of
the C64x DSP with added functionality and an expanded instruction set.
Reference Guides—
— TMS320C6452 DSP DDR2 Memory Controller User's Guide describes the DDR2 memory
controller in the TMS320C6452 Digital Signal Processor (DSP). The DDR2/mDDR memory
controller is used to interface with JESD79D-2A standard compliant DDR2 SDRAM devices and
standard Mobile DDR SDRAM devices.
— TMS320C6452 Peripheral Component Interconnect (PCI) User's Guide describes the
peripheral component interconnect (PCI) port in the TMS320C6452 Digital Signal Processor (DSP).
The PCI port supports connection of the C642x DSP to a PCI host via the integrated PCI
master/slave bus interface. The PCI port interfaces to the DSP via the enhanced DMA (EDMA)
controller. This architecture allows for both PCI master and slave transactions, while keeping the
EDMA channel resources available for other applications.
