Functional Block Diagram Features
The OMAP5910 device includes the following functional blocks:
ARM9TDMI-based MPU core
16K-byte instruction cache and 8K-byte data cache
Memory Management Units (MMUs) for Instruction and Data
Two 64-entry Translation Look-Aside Buffers (TLBs) for MMUs
17-word write buffer
C55x DSP subsystem
48K-word single-access RAM (SARAM) (96K bytes)
32K-word dual-access RAM (DARAM) (64K bytes)
16K-word ROM (32K bytes)
24K-byte instruction cache
Six-channel DMA controller
Hardware Accelerators for DCT, iDCT, pixel interpolation, and motion estimation
Nine-channel system DMA controller
Traffic controller providing shared access to three memory interfaces:
EMIFF External Memory Interface providing 16-bit interface to 64M bytes of standard SDRAM
EMIFS External Memory Interface providing 16-bit interface to 128M bytes of Flash, ROM, or
asynchronous memories
Internal Memory Interface (IMIF) providing 32-bit interface to 192K bytes of internal SRAM
DSP Memory Management Unit (MMU) configured by the MPU
MPU Interface (MPUI) allowing MPU and System DMA to access DSP subsystem memory and DSP
public peripherals
Local Bus Interface (with MMU) allowing USB host peripheral direct access to system memories.
DSP Private Peripherals (accessible only by the DSP)
Three 32-bit general-purpose timers
Watchdog timer
Level 1/Level 2 interrupt handlers
DSP Public Peripherals (accessible by the DSP, DSP DMA, and the MPU via the MPU interface)
Two Multichannel Buffered Serial Ports (McBSPs)
Two Multichannel Serial Interfaces (MCSIs) ideal for voice data
MPU Private Peripherals (accessible only by the MPU)
Three 32-bit general-purpose timers
Watchdog Timer
Level 1/Level 2 interrupt handlers
Configuration Registers for pin-multiplexing and other device-level configurations
LCD controller supporting monochrome panels or STN and TFT color panels
