Writing TMS320C8x PP Code Under the Multitasking Executive
Texas InstrumentsThe purpose of this document is to supplement the TMS320C8x Multitasking Executive (ME) User's Guide and to provide useful guidelines for writing Parallel Processor (PP) assembly language or C code that can run under the executive. ME tasks running on the Master Processor (MP) may issue commands to the PPs. These commands are requests for the PPs to execute a routine and then optionally inte
Calculating CRC With TI Battery Management Products
Texas InstrumentsCertain Texas Instuments (TI) products such as the 1K-bits EPROM bq2022 the battery monitor bq2023 and the security IC bq26150 require the host to be able to calculate a cyclic redundancy check (CRC) based on a specific polynomial. The purpose of this document is to briefly discuss what a CRC is how it is used within the mentioned TI products and how to implement it within a system that intera

Addressing Peripherals as Data Structures in C
Texas InstrumentsA DSP's peripheral-specific registers can be manipulated in C. Two methods are presented for handling this task. Each method has different advantages and disadvantages. Method 1 is very useful for addressing peripheral or memory buffers that are device specific. Method 2 is preferred for addressing peripherals or memory buffers which are not device specific (i.e. peripherals are user specified).
