Chronicles from our peeps.
ASH1 communicates externally with two kinds of components, a master controller (master CPU) and a typical PHY interface unit that couples ASH1 with peripherals. The communication is achieved through the following signals: Interfacing with Signal Width Direction/ Type (with respect to ASH1) Master CPU clk 1 i reset 1 Read more…
As I have mentioned in the previous post, this and the coming posts would describe ASH1 architecture and special features. Below is the block diagram of ASH1. It consists of a data stack, a control unit, a program counter, an arithmetic/ logic unit (ALU), a cyclic redundancy checksum (CRC) Read more…
One of ASH1 features is that it can perform – what we can call – software-controlled CRC calculation. As we know CRC incorporates bit shifting, xoring and in sometimes inversion. We decided to have a unit in ASH1 that is dedicated to all these operations. For instance, we want to Read more…
It’s always nice to have a meeting at AESTE. It charges you up and gives you the necessary motivation. If you want to get motivated … AESTE should be your destination where you can see ambitious people pursuing their passion.. For the next phase of my work on ash1. It’s Read more…
Hi again ! As the goal for ash1 is to make it as small and as fast as possible. I’ve tried to investigate the size and speed features of ash1. As we have seen from the previous post, ash1 is pretty small (~500 FPGA slices)… I guess this is super Read more…
It has been a while since my last blog … I was busy with my exams and university issues for about a month. So, here we come again to talk about ash1. Since I have started working on ash1, I was anxiously waiting for the day where I can write Read more…
I was being informed that my blog posts were too technical until a point that it bored the readers. I felt pity for my supervisor, because he needs to read through all my dull blog posts before publishing them. The reason that I prefer to blog technical stuff is that Read more…
Processes can be classified as either I/O-bound or processor-bound. As the name suggests, the former is a process where much of the time is spent in waiting for relatively slow I/O operations to complete. For instance, a process taking input for a word processor will be I/O-bound as it spends most of its time Read more…
Continue from my previous post, LLVM: Compiling FreeRTOS with LLVM (Part 1). Anybody who might have some basic skills in programming, creating Makefiles especially, must be laughing hysterically if they come across and read my previous post in this topic. When I google the phrase “Compiling freertos with llvm” or Read more…
Multitasking operating system is a software that offers interleave execution of more than one process. It is capable of executing several processes concurrently and therefore giving an illusion of parallelism in the view of user abstraction. Multitasking operating systems come in two flavors: cooperative multitasking and preemptive multitasking. In cooperative multitasking, a process does not stop running until it is Read more…
