Is this the same SPI controller design > like in AMCC's 40x and 44x cores, i. e. with a "FIFO" of depth 1? It is a ppc440 but it is does not have ans spi controller as in the amcc. The spi controller is a xilinx core allocated at the plb bus, including a deeper fifo. The actual version does not have a sustained speed of 33Mhz but a can have a peak speed of 33 MHz Thanks for your comment -- Ricardo Ribalda http://www.eps.uam.es/~rribalda/
