技术资料  shift_register_ram

Altera provides a RAM-based shift register megafunction called ALTSHIFT_TAPS that contains additional features not found in a conventional shift register. Traditional shift registers implemented with standard flip-flops use many logic cells for large shift registers. The ALTSHIFT_TAPS megafunction i ...

技术资料  微波工程

5’ummary-A circularly symmetric power divider is described which splits a signal into n equiphase equismplitude parts where n can be odd or even. The power divider provides isolation between output terminals and approximately matched terminal impedances over about a 20 per cent band. A theory of op ...

DSP编程  This document describes how to switch to and program the unisersal serial bus (USB) analog phase-lo

This document describes how to switch to and program the unisersal serial bus (USB) analog phase-locked loop (APLL) on the C5506/C5507/C5509A devices. Example assembly programs for programming and switching to and from the APLL are also provided in the attached zip file. It is assumed that the reade ...
