Digital television (DTV) has been adopted by most markets thanks to MPEG-2 compression technology, but the picture is not that simple. H.264-AVC (MPEG-4 Part 10) and Microsoft's VCI compression standa...
My clock cycle is 1/20uS, so my interrupt response time should be around 5/20uS, but the actual measured response time is around 2.5uS, which is much longer. I don't know what causes this? Can anyone ...
When I used QuartusII to simulate the I2C bus, I wrote a task task shift_in; output [7:0] shift; begin @(posedge scl) shift[7] = sda; @ (posedge scl) shift[6] = sda; @ (posedge scl) shift[5] = sda; @ ...
