Digilent [246] 32-bit MIPS-M4K PIC32MX processor boards (40-80 MHz). The Arduino libraries have been implemented natively for the PIC32MX and these kits run in a fork of the standard Arduino IDE, MPIDE [247] and are compatible to most shields.

This is known as in-circuit programming. To support in-circuit debugging and programming requirements, the HC08 Family has the monitor mode and the HCS08 and RS08 utilize a background debug mode (BDM). The background debug hardware on the HCS08 consists of a background debug controller (BDC) and debug module (DBG).
Early versions of Digital Research's CP/M and CP/M-86 kept the DEC name DDT (and DDT-86 and DDT-68K) for their debugger, however, now meaning Dynamic Debugging Tool. [ 1 ] [ 2 ] The CP/M DDT was later superseded by the Symbolic Instruction Debugger (SID, [ 3 ] ZSID, SID86 , [ 4 ] and GEMSID ) in DR DOS and GEM .
The instruction set also varies by model, with more powerful chips adding instructions for digital signal processing functions. The hardware implementations of PIC devices range from 6-pin SMD , 8-pin DIP chips up to 144-pin SMD chips, with discrete I/O pins, ADC and DAC modules, and communications ports such as UART , I2C , CAN , and even USB .
On-chip debugging is an alternative to in-circuit emulation. It uses a different approach to address a similar goal. On-chip debugging, often loosely termed as Joint Test Action Group (JTAG), uses the provision of an additional debugging interface to the live hardware, in the production system. It provides the same features as in-circuit ...
JTAG (named after the Joint Test Action Group which codified it) is an industry standard for verifying designs of and testing printed circuit boards after manufacture.. JTAG implements standards for on-chip instrumentation in electronic design automation (EDA) as a complementary tool to digital simulation. [1]
Below is the full 8086/8088 instruction set of Intel (81 instructions total). [2] These instructions are also available in 32-bit mode, in which they operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts.
The initiative has developed 5 RISC-V microprocessors that run on FPGAs boards. [10] The ET1031 is a 32-bit processor, with all other processors being 64-bit. [10] Only the 32-bit variant has been physically manufactured within a THEJAS SOC.
