Dual-ported RAM (DPRAM), also called dual-port RAM, is a type of random-access memory (RAM) that can be accessed via two different buses.. A simple dual-port RAM may allow only read access through one of the ports and write access through the other, in which case the same memory location cannot be accessed simultaneously through the ports since a write operation modifies the data and therefore ...
MyHDL [1] is a Python-based hardware description language (HDL).. Features of MyHDL include: The ability to generate VHDL and Verilog code from a MyHDL design. [2]The ability to generate a testbench (Conversion of test benches [3]) with test vectors in VHDL or Verilog, based on complex computations in Python.
Dual-ported RAM allows the CPU to read and write data to memory as if it were a conventional DRAM chip, while adding a second port that reads out data. This makes it easy to interface with a video display controller (VDC), which sends a timing signal to the memory and receives data in the correct sequence as it draws the screen.
This ambiguity is intentional. Wishbone is made to let designers combine several designs written in Verilog, VHDL or some other logic-description language for electronic design automation (EDA). Wishbone provides a standard way for designers to combine these hardware logic designs (called "cores"). Wishbone is defined to have 8, 16, 32, and 64 ...
A pin controlled by the CPU separates this bus into two "ports", a control port and a data port. To write or read a byte of video memory, the CPU first has to write two bytes on the VDP's control port to the VDC's internal address register. Next, the CPU performs the actual write or read on the VDP's data port.
The HDL code then undergoes a code review, or auditing. In preparation for synthesis, the HDL description is subject to an array of automated checkers. The checkers report deviations from standardized code guidelines, identify potential ambiguous code constructs before they can cause misinterpretation, and check for common logical coding errors ...

Core 2 increased the inner ring bus to 24 bytes (allow more than 3 instructions to be decoded) and extended its register file from dual-ported (one read/one write) to quad-ported (two read/two write), register still remain 8 entries in 32 bit and 32 bytes (not including 6 segment register and one instruction pointer as they are unable to be ...
