' It was that year at the winter NAMM (National Association of Music Merchants) show that they introduced their Prophet-5, which was 'exactly the kind of instrument, with exactly the kind of sound and features, that musicians needed.' 'The Prophet-5 rocketed Smith's garage operation to stunning heights. They were 'a self-funded outfit that started out in the confines of Smith's San Jose, California, garage selling a digital sequencer and a generic synth programmer. In 1978 Sequential Circuits consisted of Dave Smith, former Moog clinician John Bowen, and businesswoman Barb Fairhurst. Search the Classifieds for this manufacturer.

With the correct design, you could improve this and get one output per clock cycle, with a 30-cycle delay, by having a full pipeline and passing data through it at every clock cycle.Home Site Map About Us Contact Us Support Us However, you will need to wait 30 cycles for a result, simply because the steps are part of a synchronous pipeline. Each of those steps might be easier to place-and-route efficiently, meaning that you get overall better performance because of the improved routing of each step. In the sequential design, you have multiple smaller steps, the slowest of which takes 1.275ns in the worst case. You'll just see the instant calculation of your combinational function in your simulation.

Your simulator is not telling you everything, since a behavioral simulation will not show gate propagation delays. The first Sequential Circuits product was an analog sequencer for use with Moog and ARP synthesizers, followed by a digital sequencer and the Model 700. The combinational circuit will cause each input to go through the propagation delays of the entire algorithm, which will take at up to 1701.691ns on the FPGA you are working with, because the slowest critical path in the combinational circuitry needed to calculate the result will take up to that long. If anyone knows what it is and/or where it comes from feel free to comment. What you are seeing is pipelining and its performance benefits. So now this 1.575 ns is the delay between any of the 2 registers, its not the propagation delay of entire algorithm so how can i calculate propagation delay of entire pipelined algorithm. And these registers are controlled by clock so now this pipelined design is giving design summary asĬlock period 1.575 ns and freq 634.924 MHz Now I have applied pipe-lining to the combinational logic by inserting the registers in between the 5 main blocks which are doing the computation.

The design has been simulated in Xilinx ISE Why this design is slow can any one explain please? In this way combinational is faster as we are getting instant output but why frequency of operation of combinational one is lesser than sequential one. But the simulation results I m getting for sequential is after 30 clock cycles where as combinational there is no delay in the output as there is no clock. So i want to ask is it correct that combinational will have lesser frequency than sequential?Īs far as theory is concerned combinational design should be faster than sequential. Minimum clock period 1701.691 ns and Maximum frequency 0.588 MHz. While the combinational one which is designed without clock and has been put between input and output registers is giving synthesis report as Minimum clock period 1.275 ns and Maximum frequency 784.129 MHz.
