This paper reports the design of two courses, "embedded hardware'' and "embedded software" offered in 2008 spring semester at Hiroshima University. These courses use 16-bit processor TINYCPU, cross assembler TINYASM, and cross compiler TINYC. They are designed very simple and compact: The total number of lines of the source code is only 427. Thus, students can understandthe entire design...
The main contribution of this paper is to present a simple, scalable, and portable tiny processing system which can be implemented in various FPGAs. Our processing system includes a 16-bit processor, a cross assembler, and a cross compiler. The 16-bit processor runs in 89 MHz on the Xilinx Spartan-3A family FPGAXC3S700A using 336 out of 5888 slices (5.7%)and in 76 MHz on the Altera Cyclon III family...
A 125 MHz 1 GIPS at 1.3 V 1 W microprocessor with single-chip tightly-coupled multiprocessor architecture and low-voltage circuits is targeted to high-performance and low-power embedded systems, especially smart information terminals. This paper shows an entire chip diagram integrating four tightly-coupled processors. Each processing element (PE) is in-order two-way issue superscalar with two ALU...
