TMS320C6000 C Compiler: C Implementation of Intrinsics
Texas InstrumentsThe first optimization step that you can perform on C source code for the TMS320C62xx is to use intrinsic operators. Intrinsics are used like functions and produce assembly language statements that would otherwise be inexpressible in C. The problem is that once you have performed the first optimization step your C source code is no longer ANSI C compatible. The code proposed within this appli

This document describes the conditions that can cause the latch up the affected devices and pins and workarounds to prevent the latch up from occurring.Due to the multiple factors that can cause the latch-up to occur it is challenging to provide a
Setting Up TMS320C2xx Interrupts in Assembler or C
Texas InstrumentsTypically interrupts are generated by devices that need to give or take data from the Texas Instruments (TI) (tm) TMS320C2xx for example analog-to-digital (A/D) and digital-to-analog (D/A) converters or other processors. When the C2xx recognizes an interrupt signal it suspends execution of the code specific to the particular interrupt event (Interrupt Subroutine).The C2xx family supports t
