Topview ICE A - In Circuit Emulator for Philips 8051 Microcontrollers
Topview ICE A is a Low-Cost Emulator supports major Philips 80C51 microcontroller derivatives with a 40-pin count. It is connected to PC through a USB port. Emulates the microcontroller using either the built-in clock oscillator or any other clock source connected to the
microcontroller.
The built-in clock oscillator generates 2MHz, 4MHz, 5MHz, 6MHZ, 8MHz, 10MHz, 12MHz, 16MHz, 18.432MHz, 20MHz and 24MHz. The system emulates the microcontroller in single chip mode. A special emulation technology is used to make most of the microcontroller resources like 32 I/O lines and serial port available to the user.
Emulator comes with an Integrated Development Environment called Topview IDE. The IDE has built-in program editor, template generator for supported devices. The software includes a source-level debugger for C.
It gives support for Assembly language debugging, On-line assembler and dis-assembler, software trace, breakpoints and many other features. The Topview IDE runs under MS-Windows operating systems.
The code memory permits downloading and modifying of users programs with a maximum capacity of 64Kbytes. Breakpoints allow real-time execution until an opcode is executed at a specified address or at the specific line of the Source Code.
The system is supplied with User’s Manual, Topview IDE software, Emulation cable, USB cable and the required power supply.

Software Facilities:
Emulation Memory: Topview ICE - A provides 60Kbytes of space for the program memory.
Software BreakPoints: Software BreakPoints allow the real time program execution until the specific program line.
Conditional BreakPoints: A set of conditional breakpoints permit the program halting during the emulation based on specific code address, source code lines and the register contents.
Language and file formats: Topview ICE - A accepts files with many formats. It also accepts different assemblers and C languages. For the ASM program, Intel Hex format is accepted. For the C environment, both KEIL and SDCC compilers are supported.
Source Level Debugging: The Topview IDE comes with a Source Level Debugger which helps the designers debug the application code generated by both the assembler and the C language. This debugger includes the commands to generate all the required information during the program and hardware testing in real time. The commands permit setting breakpoints based on high level language lines, adding a watch window with symbols and variables of interest, modifying the variables, executing assembly steps and many more useful functions.
Topview IDE - Integrated Development Environment
This is the device selection window. From here, you select the device, operating frequency, project type and project directory.
Template created by Topview IDE for the selected device compatible to SDCC C compiler.
This is the arrangement of windows to write a program and compile the same. The Project window shows the files in the
project. You edit or type your program in the editor window and the Output window will show the output of the compiler. Editor window supports color syntax facility to make the programs easy to understand.
Topview IDE has 5 windows to show the internal details of 8051 controller.
1. Program Window - Shows the disassembly view of flash memory.
2. Register Window - Displays the internal register and it's contents.
3. Internal Memory Window - Shows the contents of Internal Data Memory.
4. Memory Bit Status Window - In this window the 128 memory bits status are displayed.
5. SFR Bit Status Window - The bit wise contents of the SFRs are displayed here.
This is the ClearView mode of Topview IDE. In this mode of viewing, all the details of the controller are brought out in a screen. This mode is very useful while debugging the program in assembly language.
This is a sample window placement on the screen while debugging a C program.
This is an another windows arrangement on the screen. Here the PC value is shown in the editor by a yellow color arrow. The current DPTR selected is shown using a red color arrow in the register window. In the bottom, the variables in the current project are displayed in the watch window. You can edit the values of the variables here. The active variables are displayed in blue color and the inactive variables are indicated in green color.
This is the mixed mode viewing of the both c and assembly language in a single window.
This is an another view of both assembly and C language programs. The contents of the flash memory is disassembled and displayed in the program window and in the editor window, the c program with it's corresponding assembly code is displayed in a single window.
