For the implementation in VHDL and the subsequent synthesis, we have used the
Xilinx ISE 12.3 which comes with integrated ISim VHDL simulator. The use of
simulator speeds up the development but at the expense of creating testbenches
which can easily become non-trivial.

The designed circuit structure is of single-clock synchronous type which is
suitable for implementation in VHDL using many parallel processes all driven
by common clock edge of same polarity. Some of the processes also contain
asynchronous reset which is needed for the initialization and
re-initialization and is synthesizable. Generics are used wherever possible to
make individual parts re-usable. Unfortunately, VHDL does not allow
unconstrained aggregates in record type so some of the bus widths have to be
hard-coded. We have at least used constant types in such cases.

= UART and Memory Controller

The important part of the entire system is the implementaion of UART along
with a memory controller. All the memories have to instantiated at the top
level so the controller is able to communicate with them. This unfortunately
leads to enormous number of signals which are needed for the interconnection.
For simplification, a set of multiplexers and demultiplexers have been
implemented. This does not lower the number of signals (in fact, it adds some)
but greatly simplifies the structure of the memory controller itself. A great
simplification would be achieved by usage of record type but since VHDL does
not allow unconstrained types in records, we are prevented from doing this. We
are still looking for a way to solve this. Let me just stress this does not
change the structure itself, we're only talking about the simplicity of
expression in VHDL.

= Memories

Memory entities are the core of all our table-based computational cores. It's
a single-clock synchronous circuit with the ability to pump and dump data by
"out-of-band" channel. This is very important since it would be non-trivial to
initialize memory contents.

= Simulation

As for the simulation, the testpench consists of instantiation of all circuit
parts and their interconnection using appropriate signals. A set of functions
is used to read and write the input and output to a text file, respectively.
We have used the std.text.io library for this data-to-text interface.

When the simulation is run, a reset is performed for a fixed amount of time.
Then, the input is fed into the circuit and the output is being recorded to be
later compared to the results of Matlab simulations. The clock is being
generated since the beginning of the simulation and keeps running until the
very end to accurately simulated the real-world conditions of the circuit.

= Synthesis

The final design has been synthesized for the Xilinx Virtex 6 FPGA and
downloaded to the device itself. An important part of the synthesis process is
mapping the actual hardware ports to input and output signals. This turned out
to be quite tricky as the official documentation describes the pin layout only
partially. We had to resolve to trial-and-error method to get the pin layout
(especially for the wide buses) right.

  Doktorand se v současnosti zabývá problematikou návrhu optimální procesorové architektury pro jednodimenzionální iterativní detekci, konkrétně detekci Turbokóku. Dále pak návrhem architektury pro iterativní sdruženou synchronizaci a detekci. V minulosti se zabýval problematikou vlivu přenosu signálu na subjektivní a objektivní kvalitu videa.
  Doktorand má splněnou obhajobu odborné studie i státní doktorskou zkoušku. V současné době zpracovává svou disertační práci s názvem "Návrh a optimalizace procesorové architektury pro pokročilé kódování přenosu".
