Naming Conventions

About DSP/BIOS 1-11

DSP/BIOS includes a number of modules that are used internally. These

modules are undocumented and subject to change at any time. Header files

for these internal modules are distributed as part of DSP/BIOS and must be

present on your system when compiling and linking DSP/BIOS programs.

1.3.2 Object Names

System objects that are included in the configuration by default typically have

names beginning with a 3- or 4-letter code for the module that defines or uses

the object. For example, the default configuration includes a LOG object

called LOG_system.

Note:

Objects you create with the Configuration Tool should use a common

naming convention of your choosing. You might want to use the module

name as a suffix in object names. For example, a TSK object that encodes

data might be called encoderTsk.

1.3.3 Operation Names

The format for a DSP/BIOS API operation name is MOD_action where MOD

is the letter code for the module that contains the operation, and action is the

action performed by the operation. For example, the SWI_post function is

defined by the SWI module; it posts a software interrupt.

This implementation of the DSP/BIOS API also includes several built-in

functions that are run by various built-in objects. Here are some examples:

❏ CLK_F_isr. Run by an HWI object to provide the low-resolution CLK tick.

❏ PRD_F_tick. Run by the PRD_clock CLK object to manage PRD_SWI

and system tick.

❏ PRD_F_swi. Triggered by PRD_tick to run the PRD functions.

❏ _KNL_run. Run by the lowest priority SWI object, KNL_swi, to run the

task scheduler if it is enabled. This is a C function called KNL_run. An

underscore is used as a prefix because the function is called from

assembly code.

❏ _IDL_loop. Run by the lowest priority TSK object, TSK_idle, to run the

IDL functions.

❏ IDL_F_busy. Run by the IDL_cpuLoad IDL object to compute the current

CPU load.

❏ RTA_F_dispatch. Run by the RTA_dispatcher IDL object to gather real-

time analysis data.
