Assembler Meetup #23, 2019/12/07

Meet in MongKok. Mainly shorten the grammar. Jenny confirmed each instruction can be translated by same five functions. We confirmed if instruction has only one operand, we have to add byte/word/dword/qword, e.g.: inc byte [ax] And some instructions such as call doesn’t support all four combinations of byte/word/dword/qword, this “call byte [ax]” will report error…

Jenny teach me code translate Not sure our method is unify or not Trying to make the grammar file shorter and uniform

Verilog syntax conflict

I guess syntax conflict or not is depend on how fpga vendor implement their verilog compile, nothing about the verilog language specification

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 , our new testing site is launched

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. Jenny and Kelvin is clearing the ADC instruction Desmond is extending to support Windows PE format

Assembler dev meeting #13

2019/09/14, we met in cityu again. I finished IMM in other project . 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…

Assembler dev meeting #10

As usual, #10 meeting was hold in CityU. We getting more familiar with Intel basic instruction set translating. Here is the actions list for next week: Zero padding, cut of pad “0” Jenny consolidate your code into well format, let us understand and give us tutorial next sat morning Desmond: nasm in linux example, able…

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?

C compiler pre-research preparation

Antlr C11 grammar is highly match with the C11 language specification, which is a very good news to us.

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.
