Abstract: in fact, in the design of a CPU, each sub module is relatively basic and simple, but the combined overall architecture will be more complex, whether it is timing path, data path and control path. Here, we mainly introduce the sub modules of the whole microarchitecture in detail. 1. PC fetch, PC branch, instruction jump and L2 stack ...

1. D trigger definition: D flip-flop is an information storage device with memory function and two stable states. The flip-flop has two stable states, namely "0" and "1". Under the action of certain external signals, it can flip from one stable state to another. The edge triggered D flip-flop is explained here. The D f ...

  summary This section mainly exercises the basic grammar of verilog. Schematic diagram + code + simulation screenshot Alwaysblock1 There are two types of composite awlays modules that can be integrated: always @(*)； The variable processed inside is reg, and the overall function is equivalent to the assign statement. The assign state ...

Getting Start In a digital circuit, 1 corresponds to a high-level signal and 0 corresponds to a low-level signal. Verilog Language Basic The keyword assign is used for continuous assignment assign left_side = right_side NOT gate, logic negates the symbol!, Bitwise inverse sign~ AND gate, logic and symbol & &, bitwise and symbol& ...

There are many tutorials about SPI. Here is a summary of my study of SPI protocol. What is SPI? SPI is the abbreviation of Serial Peripheral Interface Bus, which means serial peripheral interface. It is a synchronous serial communication interface standard for short distance communication, mainly used in embedded system. This in ...

In the development and design of FPGA, many clocks are working in the same module at the same time. At the same time, the communication between signals in the clock domain must be ensured. It is necessary to deal with the timing problem, that is, the establishment and holding time of signals.   r_PULSE_O <= { r_PULSE_O[1:0] , r_PULSE_I} ;    ...

The main exercise in lab2 is to use ucli. The structure diagram of the adder of lab2 is shown in the figure below: Bugs have been embedded in the tutorial files this time. What the tutorial does is the whole process of de bug ging. PartA and PartB use the methods of modifying source files and usi ...
