• Avoid writing low-level DSP support
• Fully exploit all DSP peripherals and bandwidth
• Support for multitasking
• Support for large, sophisticated libs and apps
• Isolation from low-level peripheral details
• Decrease time-to-market
• For our boards and for end-user system
  implementation

DSP/BIOS II Real-Time Kernel

• Fully-featured real-time kernel
• Real-time event and statistic gathering
• Preemptive priority-based multi-threaded
  operations
• Basic inter-thread communication and
  synchronization
• Basic interrupt handling capabilities
• Most blocking primitives have an optional
  time-out parameter
• Designed for DSPs
• Memory Management aligned allocs multiple
  heaps with no space overhead in allocated block
  (interface with SRAM, SDRAM, etc.)
• Low interrupt latency minimize intervals during
  which interrupts are disabled (See SPRA663)
• High performance device independent I/O
• Basic I/O for interacting with devices and other
  threads
• Asynchronous, low overhead and deterministic
  (constant completion times, not data size
  dependent)

9
DSP/BIOS II Scheduling Services

• Hardware Interrupts (HWI) Highest Priority
• have the highest priorities
• one HWI can interrupt another
• Software Interrupts (SWI)
• have lower priority than hardware interrupts
• 15 levels of priority
• can be preempted by a higher priority SWI or HWI
• Tasks (TSK)
• have lower priority than software interrupts
• 15 levels of priority
• can be preempted by a higher priority task
• Idle Functions (IDL)
• have lowest priority level and preempted by a
  TSK, SWI or HWI

10
Real-Time Analysis

• Determine whether the system is
• Operating within its design specifications
• Meeting its performance targets
• Showing any subtle timing problems (glitches)
• Analyze real-time operation
• Execution Graph
• CPU Loading
• Statistics
• Kernel Object View
• Log_printf
• If you can see the problem, you can fix the
  problem

11
Execution Graph

• Execution graph is used to view thread execution.

12
Summary

• DSP/BIOS II provides a graphical interface for
  configuring the kernels functions.
• DSP/BIOS II provides Real Time Analysis tools to
  aid in debugging process.
• DSP/BIOS II provides a pre-emptive multithreaded
  scheduling services to help construct any
  application.

What is a Device Driver?

• Software that isolates an application from I/O
  hardware
• Whats the big deal?
• Applicability
• Portability
• Efficiency
• Ease of implementation

15
Who writes drivers?

• 3rd party board vendors such as Innovative
• Available on all Pismo toolset products
• Not available for Zuma toolset products
• TI
• TI codecs only
• End users
• Not likely, but possible
