What is DSP/BIOS

• Real-time Environment
• Thread execution model
• Threads, Mailboxes, Semaphores
• Device independent I/O
• Logging, Streaming I/O
• RTDX (Real-time data exchange)
• Real-time Analysis
• Debug facility ( with CCS)
• Device Configuration and Management
• GUI based configuration in CCS

DSP/BIOS I/O Example
AudioFilter( inputPipe, outputPipe )
PIP_get(inputPipe) / dequeue full frame
/ PIP_alloc(outputPipe) / dequeue empty frame
/ copy algorithm / read/write data frames
/ PIP_free(inputPipe) / recycle input frame
/ PIP_put(outputPipe) / enqueue output frame
/ return / wait for next frame pair /

DSP/BIOS Audio I/O Example
Void audio(PIP_Obj in, PIP_Obj out) Uns
src, dst Uns size if(PIP_getReaderNumFrame
s(in) 0 PIP_getWriterNumFrames(out)0) er
ror() / get input data and allocate
output buffer / PIP_get(in)
PIP_alloc(out) / copy input data to output
buffer / src PIP_getReaderAddr(in) dst
PIP_getWriterAddr(out) size
PIP_getReaderSize(in) PIP_setWriterSize(out,siz
e) for ( size gt 0 size) dst
src / output copied data and free
input buffer / PIP_put(out) PIP_free(in)

CSL and Peripheral Configuration

Peripheral Configuration using IDE
17
System Configuration

• Allows detailed specification of target
• Memory Data and Code location
• Generates peripheral initialization code
• Interrupts, Timers, McBSP, DMA etc.
• Generates linker configuration file (.cmd)

Conclusions

• Royalty-free real-time kernel for production use
• Allows for rapid development of product from
  concept
• Can be integrated with another real-time OS
• Small footprint (can be as small as 1K words)
• Modules used are controlled by the user
• Allows for on-the-fly debug/analysis in the field
• Available with C6000 and C5000 processors
