This MCU has an embedded debug monitor ROM withĪ library of routines that can help you reduce development time. Memory bus (8–bit data and 16–bit address bus) for flexible system design. Serial Interface Bus (SIB) token passing local area network for multi–W65C134S processor systems. The W65C134S is a feature rich 8–bit microcontroller based on the W65C02 with an advanced (originally designed for life support) Provides capability for re–entrant, re–cursive and re–locatable programming. The New Direct Register and stack relative addressing

The W65C816S extends the 65xx technology family to handle 16–bit processing with a 16MB memory space while its emulation modeĪllows complete hardware and software compatibility with 64KB 6502 designs.

This chip features a full external data (8–bit) and address (16–bit) bus forĮasy integration with 8–bit peripherals and memory. However as assembler goes it was definitely RISC (before that became a thing).The W65C02S is a low power 8–bit microprocessor utilized in a vast array of products for the Automotive,Ĭonsumer, Industrial, and Medical markets. Surely whatever is coded into this 6502 routine is derived from an algorithm that you can easily translate to whatever CPU you choose? I do have a fondness for 6502 because when I was a kid I had a BBC Micro and having the best version of BBC BASIC on the planet that also had inline 6502 assembly (two pass, so labels too!) I would often drop into assembler. You can cross-compile for it with GCC which means the word is your oyster for maths packages that will run on it. However if you want a powerful home-build 'retro' SBC, why not use a Motorola 68008? You get most of the benefit of a 16 bit CPU with only an 8 bit bus, with no nasty multiplexing to deal with. If the source processor has a DAA instruction and the target processor doesn't or visa-versa, all BCD maths routines will need a total rewrite. Porting a maths package without a deep knowledge of the original architecture and instruction set and preferable a working system with debugger or accurate emulator is going to be a royal PITA, and debuggong it will be even worse. At least a 8051 has current cross-assemblers and cross-compilers available, and a Z80 system can run CPM if you provide enough RAM, bulk storage (e.g. So anyhow, what do you think I should do? Problem with the AVR is that it is Harvard and so ram and rom space is split, this isn't the case with the Z80. I want this package in a single chip AVR/8051 real bad, do you think it's viable to try and translate the 6502 assembler to AVR assembler, literally coded instruction for instruction? Failing that, I could try and port it to Z80 assembler. I've got compiler support for the 8051, AVR and the Z80.

The total code consists of about 750 instructions and fits inside a 2krom. If I build a 6502 system, then you are looking at about 10~15 chips, I have no compiler support for the 6502, other than an assembler. I want decimal floating point capability and I've got an old package by mos technology from about 1977 which basically consists of a bunch of 6502 routines that you can string together and produce a potential 16 decimal(bcd) digits of mantissa(that's very powerful). Hi folks, I'm having a tough time here trying to figure out my best next move forward.
