About This Manual

This document describes the universal serial bus OHCI host controller.

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.

SPRUFE8 — TMS320C674x DSP CPU and Instruction Set Reference Guide. Describes the CPU architecture, pipeline, instruction set, and interrupts for the TMS320C674x digital signal processors (DSPs). The C674x DSP is an enhancement of the C64x+ and C67x+ DSPs with added functionality and an expanded instruction set.

SPRUFK4 — TMS320C6745/C6747 DSP System Reference Guide. Describes the System-on-Chip (SoC) including the DSP subsystem, system memory, device clocking, phase-locked loop controller (PLLC), power and sleep controller (PSC), power management, and system configuration module.

SPRUFK5 — TMS320C674x DSP Megamodule Reference Guide. Describes the TMS320C674x digital signal processor (DSP) megamodule. Included is a discussion on the internal direct memory access (IDMA) controller, the interrupt controller, the power-down controller, memory protection, bandwidth management, and the memory and cache.

SPRUFK9 — TMS320C6745/C6747 DSP Peripherals Overview Reference Guide. Provides an overview and briefly describes the peripherals available on the TMS320C6745/C6747 DSP.

SPRUG82 — TMS320C674x DSP Cache User's Guide. Explains the fundamentals of memory caches and describes how the two-level cache-based internal memory architecture in the TMS320C674x digital signal processor (DSP) can be efficiently used in DSP applications. Shows how to maintain coherence with external memory, how to use DMA to reduce memory latencies, and how to optimize your code to improve cache efficiency. The internal memory architecture in the C674x DSP is organized in a two-level hierarchy consisting of a dedicated program cache (L1P) and a dedicated data cache (L1D) on the first level. Accesses by the CPU to the these first level caches can complete without CPU pipeline stalls. If the data requested by the CPU is not contained in cache, it is fetched from the next lower memory level, L2 or external memory.
