题目：Branch direction predictors are often structured as tables of counters indexed by the program counter and branch history. The branch history is a sequence of "taken" or "not taken" results from recent branches.In hardware, the branch history registe

原创 Fsm hdlc
Synchronous HDLC framinginvolves decoding a continuous bit stream of data to look for bit patterns that indicate the beginning and end of frames (packets). Seeing exactly 6 consecutive 1s (i.e.,01111110) is a "flag" that indicate frame boundaries. To avo..

原创 Fsm serialdp
See also:Serial receiver and datapathWe want to add parity checking to the serial receiver. Parity checking adds one extra bit after each data byte. We will use odd parity, where the number of1s in the 9 bits received must be odd. For example,10100101...

原创 Lemmings4
Although Lemmings can walk, fall, and dig, Lemmings aren't invulnerable. If a Lemming falls for too long then hits the ground, it can splatter. In particular, if a Lemming falls for more than 20 clock cycles then hits the ground, it will splatter and cease

原创 HDLBits Lemmings3
In addition to walking and falling, Lemmings can sometimes be told to do useful things, like dig (it starts digging whendig=1). A Lemming can dig if it is currently walking on ground (ground=1and not falling), and will continue digging until it reaches t..
