Assembler Dev #16 2019/10/12

We finalize our error handling method, in both antlr grammar and java instruction “ADC” fully encoded, but still some combination mis-encoded. That means nasm don’t encode it, but we do https://www.quantr.hk/asmweb , our new testing site is launched

Getting started with RISC-V

https://dantalion.nl/en/getting-started-with-risc-v/ So you have heard of this RISC-V thing typically talked about in the context of microprocessors and to a lesser degree also for desktop processors. RISC-V is an open-source hardware instruction set architecture (ISA). Similarly to how X86 for Intel and AMD is a closed source ISA. Being an open-source ISA any manufacturer can…

Assembler dev meeting #14

2019/09/21, as usual, heading to our first milestone. Enhanced the full test output, added two filters. Filter out by instruction or by error. http://www.quantr.hk/wp-content/plugins/NasmWeb/public//viewOutput.php?path=/home/gitlab-runner/output/output_300588484.html Jenny and Kelvin is clearing the ADC instruction Desmond is extending https://gitlab.com/quantr/toolchain/quantr-executable-library to support Windows PE format

Serious hanging problem in Microsoft Flow

I got a list on SharePoint Online, which is a typical list with some single-line col and one lookup field. I create a flow to get all item from it (no filtering), then use “Apply to each” to loop through all items. For testing, i got two identical loops. After i run it, one successful…

Assembler dev meeting #13

2019/09/14, we met in cityu again. I finished IMM in other project https://gitlab.com/quantr/toolchain/antlr-calculator-library . So Assembler’s parser will eat up the whole numeric string and then pass it to antlr-calculator-library, if it contains a maths expression, it return the final answer which is a number. I created another library to produce ELF output. Jenny and…

ELF Specification 1.2 is only for 32 bits

I am writing a java library to manipulate 64 bits ELF, so i read ELF specification 1.2 , but one big mistake i took is : this specification is only for 32 bits, and the 64 bits one introduce new data types. So I was trying to guess out what data types it is using…

Assembler dev meeting #11

sync-ed up Jenny coding skill to all of us. Jenny now clearing all useless code, rename variables to a more meaningful name. Our next job is to encode all instructions together, and for me, create an ELF library to output ELF format object code. Here is our tuned assembler grammar https://gitlab.com/quantr/toolchain/Assembler/blob/master/src/main/java/hk/quantr/assembler/antlr/AssemblerParser.g4

Wheatstone bridge in multisim

Simulation is correct


2019/08/12 0

Why Multisim sometime is 100% accurate than calculation, sometimes is not

This exercise is 100% same as calculation But below one is not 100% same as calculation, it use just same components: VC + Resistors. Is multisim using brute force to guess out the voltage and current values?

I thought Java swing is pixel graphic

In last 20 years, I thought Java swing is pixel graphic, but i found out it is vector. I tried to draw a 1 pixel line with 45 degrees, and when i zoom out, i proved it is not pixel base. So all drawLine, drawRect function calls are vector graphic.

THE 6TH ASSEMBLER DEV MEETING

Peter updated netbeans-antlr plugin, increase our productivity: Jenny finished the REX.W translate, she keeps translating other instructions to see if our current coding facilities enough or not. Desmond is adding all the rest of the intel instructions to the grammar file, still need sometimes.

完全痴線 – JTextComponent個setCaretPosition完來係錯

如果你放”abc\ndef”落JTextComponent, 佢會變Q左”abc\r\ndef”, 連帶影響埋setCaretPosition()會錯位,補救方法如下: 經過修正之後, 我個netbeans outline plugin回復正常了
