Type 12: SF is 4 bits (15-12), D is bit11 (not SF=3bits, D=bit12). Verified all 8 SF variants against assembler: LSHIFT/ASHIFT, HI/LO, plain/OR. FIR output scaling chain now correct. TESTING.md: Synced with actual verification status. 34 of 37 types now assembler-verified. Only Type 22/22a (2-word data write), Type 31 (IDLE), and Type 32a (DAG store+transfer) remain structural-only. Removed build artifacts (.o, .elf) from examples/build/.
ADSP-219x Radare2 Plugin
Native architecture plugin for disassembling ADSP-219x (including ADSP-2191) 24-bit instructions in radare2 and iaito.
Build & Install
make
make install
Requires: GCC, radare2 >= 5.8.0 (RArchPlugin API).
Usage
r2 -a adsp219x -b 24 firmware.bin
Validation
Compare against the assembler-verified test ROM:
r2 -a adsp219x -b 24 -q -c "pd 48" ../examples/isa_test.bin
The test ROM (isa_test.dsp) was assembled with open21xx and
contains known opcodes for all major instruction types.
