Publication number: 20150205613Abstract: A processor includes an instruction fetch unit and an instruction decode unit. The instruction fetch unit includes an instruction pre-fetch buffer and is configured to fetch instructions from memory into the instruction pre-fetch buffer. The instruction decode unit is coupled to the instruction pre-fetch buffer and upon decoding a call instruction from the instruction pre-fetch buffer, causes next N instruction words of the instruction pre-fetch buffer to be preserved for execution after completing execution of a software module indicated by the call instruction, and causes the instruction fetch unit to begin fetching instructions of the software module from the memory at an address indicated by the call instruction. Upon completion of execution of the software module, the instruction decode unit begins to decode the preserved N instruction words while the instruction fetch unit concurrently fetches instruction words from beginning at an address after the N instruction words.Type: ApplicationFiled: January 21, 2014Publication date: July 23, 2015Applicant: TEXAS INSTRUMENTS DEUTSCHLAND GMBHInventors: Shrey BHATIA, Christian WIENCKE

Publication number: 20150177326Abstract: A system on a chip (SoC) includes a transceiver comprising a transmitter having a power amplifier and a receiver having a signal buffer. At least one of the transmitter and receiver has a configurable portion that can be configured to produce a range of waveforms (both in waveshape as well as duty cycle). A low cost built in self test (BIST) logic is coupled to the transceiver. The BIST logic is operable to calibrate the configurable portion of the transceiver to produce a waveform that has a selected harmonic component that has an amplitude that is less than a threshold value. Current consumed by the transceiver may be dynamically reduced by selecting an optimized waveform that has low harmonic components.Type: ApplicationFiled: December 20, 2013Publication date: June 25, 2015Applicants: Texas Instruments Deutschland GMBH, Texas Instruments IncorporatedInventors: Sudipto Chakraborty, Jens Graul
