What is Handel-C?




a C-based language
not a hardware description language: it supports
abstractions common for software programmers
Reasonably complex system can be design
easily
High level yet allow description of sequential and
parallel logic

Development Timeline
Week 1 – Getting familiar with the DE2 board and Handel-C
Week 2 – Research in building a library in Handel-C and writing simple VHDL functions
Week 3 – Use Handel-C to program the board
Week 4 to week 8 – Developing Drivers (writing and testing)
Week 9 – Writing the Manual and Instructions
Week 10 – Preparing the Demos and finishing off the Manual
Week 11 – Trying to add a camera to the DE2 board with the written drivers

Library Components
Library file: .hcl
 Header file: .hch
 VHDL Functions Components

 PS/2
mouse
 Video Driver
 LCD module
| Hardware & Software | Development | Demonstration | Summary |
10
Library file .hcl
Generated by using DK Library project
 Create a .hcc file containing macros
 Compile the project to obtain the .hcl file
 Example macro procedure:

macro proc DE2SetLEDGs(mask)
{
interface bus_out() LEDG(mask)
with {data={"Y12","Y18","AA20","U17","U18","V18","W19","AF22","AE22"}};
}
| Hardware & Software | Development | Demonstration | Summary |
11
Header file .hch
Describe the macros in the library
 Example:

typedef signal unsigned 9 DE2_LEDG_MASK;
extern macro proc DE2SetLEDGs(mask);

12
Interfacing with VHDL
Some functions are written in VHDL
 It is useful to interface with VHDL code
 Example:

interface LCD_DISPLAY(unsigned 1 LCD_RS, unsigned 1 LCD_E,
unsigned 1 LCD_RW, unsigned 8 DATA_BUS)
LCD(unsigned 1 re_set=key0.in, unsigned 1 clk_50Mhz = clk_in.in,
unsigned 256 Hex_Display_Data=line)
with {vhdl_type="std_logic_vector"};
| Hardware & Software | Development | Demonstration | Summary |
13
Example User’s Program

in the “sample code” folder
set clock = external "N2";
#include "DE2.hch"
void main(void)
{
DE2_SW_MASK SW;
do
{
DE2SW(SW);
//read inputs from the toggle switches
DE2SetLEDRs(SW); //shows the status of the switches on LEDs
} while(1);
}

Designing with the Library?
Include the DE2 Library
Program in Handel-C
Compile in DK – Outputs: EDIF file & tcl script
Run the tcl script and Compile the EDIF file in Quartus II
Simulate or Download the design on to the DE2 board
