Texas InstrumentsThis document describes how to determine the number of CPU cycles required to transfer data between the host CPU and the Texas Instruments (TI) (tm) TMS320C6201/6701 digital signal processor (DSP) using the Host Port Interface (HPI).The host has direct access to the processor's data memory via the 16-bit HPI. The number of cycles required for a data transfer between the host CPU and the TMS320
AN-79 IC Preamplifier Challenges Choppers on Drift (Rev. B)
Texas InstrumentsSince the introduction of monolithic IC amplifiers there has been a continual improvement in DC accuracy.Bias currents have been decreased by 5 orders of magnitude over the past 5 years. Low offset voltagedrift is also necessary in a high accuracy circuits. This is evidenced by the popularity of low drift amplifiertypes as well as the requests for selected low-drift op amps. However until n
Fully integrated TPS6300x buck-boost converter extends Li-ion battery life
Texas InstrumentsFor portable power applications to take advantage of the small size and high energy density of modern battery technology, they must operate efficiently over the full battery-discharge voltage range. This presents a design challenge for Li-ionpowered systems requiring a 3.3-V bus. While standard buck converters excel at efficiently converting a 4.2- to 3.0-V Li-ion battery to lower output voltages such as 1.8 V, and standard boost converters efficiently convert a Li-ion battery to higher output voltages such as 5 V, neither provides an optimal solution for generating the everpresent 3.3-V bus. Topologies such as the SEPIC and traditional buck-boost utilize the full battery capacity but suffer from drawbacks such as low efficiency, high cost, increased board area, and high part count. The TPS6300x, available in three configurations, can solve many of these problems. The TPS63000 has an adjustable output from 1.2 V to 5.5 V. The TPS63001 and TPS63002 outputs are fixed at 3.3 V and 5.0 V, respectively. All are available in the space-saving 10-pin QFN (DRC) package.

Using the CDC3S04
Texas InstrumentsWhen designing a single-ended clock tree a system designer can choose between two commonly-used waveform types: rectangular or sinusoidal. This application note gives a short overview of both signal types and shows the advantages and disadvantages of each using the CDC3S04 quad sine-wave clock buffer with an integrated low-dropout regulator (LDO). Additionally the clipped sinusoidal waveform is

Inter-Core Communication on TMS320C6474
Texas InstrumentsInter-core (also called Inter-CPU or Inter-Processor) communication on the C6474 multi-core DSP devices can be accomplished using the on-chip inter-processor communication (IPC) module. The main function of the IPC module is to provide inter-core interrupts. Optionally flags can be sent along with an interrupt for implementation or more advanced inter-core communication protocols.
