Texas Instruments TMS320C64X manual Rtos Real-time operating system

Glossary

reset: A means of bringing the CPU to a known state by setting the registers and control bits to predetermined values and signaling execution to start at a specified address.

RTOS Real-time operating system.

S

service layer: The top layer of the 2-layer chip support library architecture providing high-level APIs into the CSL and BSL. The service layer is where the actual APIs are defined and is the interface layer.

synchronous-burst static random-access memory (SBSRAM): RAM whose contents do not have to be refreshed periodically. Transfer of data is at a fixed rate relative to the clock speed of the device, but the speed is increased.

synchronous dynamic random-access memory (SDRAM): RAM whose contents are refreshed periodically so the data is not lost. Transfer of data is at a fixed rate relative to the clock speed of the device.

syntax: The grammatical and structural rules of a language. All higher-level programming languages possess a formal syntax.

system software: The blanketing term used to denote collectively the chip support libraries and board support libraries.

T

tag: The 18 most significant bits of the program address. This value corresponds to the physical address of the fetch packet that is in that frame.

timer: A programmable peripheral used to generate pulses or to time events.

TIMER module: TIMER is an API module used for configuring the timer registers.

W

word: A multiple of eight bits that is operated upon as a unit. For the C6x, a word is 32 bits in length.
