ST7 AND ST9 PERFORMANCE BENCHMARKING
5.10 80C51 MCU TOOLS
Hardware tools
Software tools
P80C32GBPN chip
MicroTek EASYPACK 8051 serial emulator
Note that the internal chip frequency on evaluation board was 12 MHz, but as 20 MHz versions
are available, this frequency was used for results (execution time values have been divided by
20/12).
IAR 8051 assembler
5.11 KS88 MCU TOOLS
Hardware tools
Software tools
KS880504 and KS880116 chips
SMDS II in-circuit emulator (Samsung Microcontroller Development System 2) with target boards
TB880504A and TB880116A
A function generator has been used to reach the 8 MHz frequency. It has been connected to the
Personality Board in the SMDS2 emulator after having selected the EXTRA clock source with the
switches in the front panel.
Note that this MCU do not own any internal RAM - register file space excepted. It was also
impossible to emulate external memory. Tests have been performed using register file only.
Everything is done from the SMDS operating program software (DOS environment). SAMA
(Samsung Assembler) is used to assemble the programs with the following command line and
options:
SAMA.EXE %S /K /LST
Then, the program is loaded to SMDS2 memory (emulation memory) and a work file is made ([M]
key). The debugging screen is accessed with the [D] key.
5.12 78K0 MCU TOOLS
Hardware tools
Software tools
µPD78P014 chip
78K0 starter kit
Note that it was not possible to emulate external RAM.
The µPD78P014 toolchain consists of a Micro Series assembler (A78000) and a Micro Series
generic linker (XLINK). The command lines are as follows:
A78000 'name'.asm 'name'.lst
xlink 'name' -o 'name'.o -f bench.xcl
The file bench.xcl extends the length of xlink command line. The extra options included in
bench.xcl are:
-c78000
-Fnec
-Z(CODE)INTVEC=8000
-Z(CODE)CODE=8080
-Z(DATA)DATA=FB00
-Z(DATA)WRKSEG,SHORTAD=FE20-FEDF
-Z(BIT)BITVARS=0
-Y2
The 78K0 starter kit has a DOS environment.
