A Whole New World

Hi everyone, I’ve just started my work as an Intern Engineer in AESTE and today marks the fourth day which I have spent in this company. For the next 15 weeks (if I’m still an intern here), I will fill up this blog with my weekly personal experiences and learning Read more…

A Deeper Look on RISC-V Angel

This week, I had really a hard time with RISC-V Angel. It started with finding the bootloader code from the RISC-V Proxy Kernel, as the bootloader is the primary program/codes┬áthat needs to be load up before the main program actually runs. I searched all over the proxy kernel code and Read more…

Instruction Set Architecture

RISC-V instruction set architecture (ISA) is designed to support computer architecture research and education, and completely free for academia and industry use.┬áBy using the reference of RISCV-Angel, which is running with the RV64 (64-bit) architecture. My task is to make sure that the RISCV-Angel is able to run on the Read more…

ISA Size Comparison

Just to do a quick and dirty comparison of several popular ISAs, I compiled a simple C application that calculates primes using the Sieve of Eratosthenes using the following command: gcc -O2 -c -o prime.o prime.c Then, I compared the output binaries just on memory size using the ELF size Read more…

Free ISA

While work has been under way on our new processor core, which shall remain multi-threaded using interleaved multi-threading in hardware, we have been searching for a free ISA to use as the base instruction set. Our previous microprocessor was based on the Microblaze instruction set (ISA). While there is nothing Read more…
