In addition to the interface of a circuit with its environment, we need to describe the functionality of the circuit. In Figure 1, the functionality of the circuit is to AND the two inputs and put the result on the output port. To describe the operation of the circuit, V...

This is part of the VHDL language specification. The code below uses integer. The definition of the constant is simple. library IEEE; use ieee.std_logic_1164.all; use ieee.numeric_std.all; entity signed_adder is Port ( clk : in std_logic; rst : in std_logic; Q : o...
Or maybe you need to do8B/10Bencoding/decoding, which is used commonly in Ethernet, HDMI, SATA, USB, etc. These would be great applications for single port Block RAMs. The way they work is all based on aClock. Data will be read out on the positive edge of the clock cycle at the a...
and is used by the RCMP (routing, cell counting, monitoring, policing) process in a network port interface for an ATM switch fabric. The available behavioral level VHDL design was translated to a synthesizable Verilog set and verification was carried out using the VIS (verification interacting ...
The Virtex 36 Kbit, dual-port RAM block resources, come programmable, especially from 32K x 1 to 512 x 72, in diverse width and depth configurations. Additionally, every 36-Kbit block can get configured to function as two autonomous 18-Kbit dual-port RAM blocks. Remember, every port is fu...
Here is an example of HDL code: 1 entity Circuit_1 is 2 Port ( a : in STD_LOGIC; 3 b : in STD_LOGIC; 4 out1 : out STD_LOGIC); 5 end Circuit_1; --- 6 architecture Behavioral of Circuit_1 is 8 begin 9 out1 <= ( a and b ); 10 end Behavioral; The electrical behavior...
Multi-port memory controllers – interfaces external memories like DDR SDRAM Serial transceivers – enables high speed interfacing for protocols like PCIe, Ethernet,USBetc. Analog-to-digital converters (ADCs) – allows analog data acquisition

Bank switching on the 6502 is complicated by the fact there is no IO address space like the Z80 has. The C64 used the built in IO port of the 6510 at hard-wired address 0/1, but the 6502 doesn’t have that. So the memory page with the memory mapped IO to control the bank swit...
