The use of IEEE.std_logic_1164.all is also required before the entity, like: library IEEE; use IEEE.std_logic_1164.all; entity lab2 is The first IEEE.std_logic_1164.all only applies to the package, and package body of the same package, but not to any other design objects like an entity or package, even if these happens to 3.2.

Both tri-state buffers are implemented in the same VHDL code of a single project. Literals for arrays of characters, such as string, bit_vector and std_logic_vector are placed in double quotes: constant FLAG :bit_vector(0 to 7) := "11111111"; constant MSG : string := "Hello"; Bit vector literals may be expressed in binary (the default), opctal or hex. Apart from that, a ping-pong buffer can definitely be implemented. The challenge is that, unlike Verilog/VHDL, switching between the buffers may take some time - HLS doesn't give you control over exactly what happens on each clock cycle. As long as there's a FIFO before the block, this isn't an issue, as the FIFO will tolerate the delay. 23.5 Doublebuffering 507 23.6 Load balance 511 23.7 Variableloads 512 23.8 Resourcesharing 516 Summary 517 Bibliographicnotes 518 Exercises 518 24 Interconnect 521 24.1 Abstractinterconnect 521 24.2 Buses 522 24.3 Crossbarswitches 524 24.4 Interconnectionnetworks 527 Summary 529 Bibliographicnotes 529 Exercises 530 25 Memorysystems 532 25.1 VHDL components for the BlockRAMs can be generated by the Xilinx Core Generator’s dual port SRAM generator.

"result same" means the result is the same as the right operand. Binary operators take an operand on the left and right.

And outside the process we assign the value of C_dummy to the output port C. This is how we reduce the buffer usage in vhdl.

This is bad! The tools recognize that this module is a sub-module, so it cannot have a tristate buffer inside the FPGA.
