// license:BSD-3-Clause // copyright-holders:Ryan Holtz /* Atmel 8-bit AVR simulator - Notes - Cycle counts are generally considered to be 100% accurate per-instruction, does not support mid-instruction interrupts although no software has been countered yet that requires it. Evidence of cycle accuracy is given in the form of the demoscene 'wild' demo, Craft, by [lft], which uses an ATmega88 to write video out a 6-bit RGB DAC pixel-by-pixel, synchronously with the frame timing. Intentionally modifying the timing of any of the existing opcodes has been shown to wildly corrupt the video output in Craft, so one can assume that the existing timing is 100% correct. Unimplemented opcodes: ELPM, SPM, SPM Z+, EIJMP, SLEEP, BREAK, WDR, EICALL, JMP, CALL - Changelist - 23 Dec. 2012 [Sandro Ronco] - Added CPSE, LD Z+, ST -Z/-Y/-X and ICALL opcodes - Fixed Z flag in CPC, SBC and SBCI opcodes - Fixed V and C flags in SBIW opcode 30 Oct. 2012 - Added FMUL, FMULS, FMULSU opcodes [MooglyGuy] - Fixed incorrect flag calculation in ROR opcode [MooglyGuy] - Fixed incorrect bit testing in SBIC/SBIS opcodes [MooglyGuy] 25 Oct. 2012 - Added MULS, ANDI, STI Z+, LD -Z, LD -Y, LD -X, LD Y+q, LD Z+q, SWAP, ASR, ROR and SBIS opcodes [MooglyGuy] - Corrected cycle counts for LD and ST opcodes [MooglyGuy] - Moved opcycles init into inner while loop, fixes 2-cycle and 3-cycle opcodes effectively forcing all subsequent 1-cycle opcodes to be 2 or 3 cycles [MooglyGuy] - Fixed register behavior in MULSU, LD -Z, and LD -Y opcodes [MooglyGuy] 18 Oct. 2012 - Added OR, SBCI, ORI, ST Y+, ADIQ opcodes [MooglyGuy] - Fixed COM, NEG, LSR opcodes [MooglyGuy] */
