Designing an Embedded Operating System With the TMS320 Family Of DSPs (Rev. A)
Texas InstrumentsApplication software targeted for today's digital signal processors (DSP) is becoming more complex. DSPs are now incorporated with numerically intensive algorithms and must perform complex system control and communication protocols previously relegated to general-purpose microprocessors. When a complicated control is mixed with DSP software the problem arises of how to implement a real-time ker
How to Get Started With the DSP/BIOS Kernel
Texas InstrumentsDSP/BIOS™ is TI's real-time embedded kernel for the TMS320C5000™ and TMS320C6000™ digital signal processors (DSPs). Understanding how to build applications using the DSP/BIOS kernel requires adopting a multi-threaded design paradigm that at first seems foreign for new users of DSPs and veteran DSP developers alike. However once understood designing DSP/BIOS applications becomes s
1K X 9 X 2 Asynchronous FIFOs - SN74ACT2235/2236 (Rev. B)
Texas InstrumentsTexas Instruments (TI) designed the SN74ACT2235 to meet a variety of synchronous or asynchronous bidirectional applications. Two 1K x 9 first-in first-out (FIFO) memories are arranged in parallel to buffer data in opposite directions. Data ports also can exchange real-time data. Three-state control (GAB GBA) and real-time/stored data select (SAB SBA) match the popular ?652 transceiver logic. Pr
