- * Texas Instruments TMS32010 DSP Emulator *
- * *
- * Copyright Tony La Porta *
- * *
- * Notes : The term 'DMA' within this document, is in reference *
- * to Direct Memory Addressing, and NOT the usual term *
- * of Direct Memory Access. *
- * This is a word based microcontroller, with addressing *
- * architecture based on the Harvard addressing scheme. *
- * *
- * *
- * *
- * **** Change Log **** *
- * *
- * TLP (13-Jul-2002) *
- * - Added Save-State support *
- * - Converted the pending_irq flag to INTF (a real flag in this device) *
- * - Fixed the ignore Interrupt Request for previous critical *
- * instructions requiring an extra instruction to be processed. For *
- * this reason, instant IRQ servicing cannot be supported here, so *
- * INTF needs to be polled within the instruction execution loop *
- * - Removed IRQ callback (IRQ ACK not supported on this device) *
- * - A pending IRQ will remain pending until it's serviced. De-asserting *
- * the IRQ Pin does not remove a pending IRQ state *
- * - BIO is no longer treated as an IRQ line. It's polled when required. *
- * This is the true behaviour of the device *
- * - Removed the Clear OV flag from overflow instructions. Overflow *
- * instructions can only set the flag. Flag test instructions clear it *
- * - Fixed the ABST, SUBC and SUBH instructions *
- * - Fixed the signedness in many equation based instructions *
- * - Added the missing Previous PC to the get_register function *
- * - Changed Cycle timings to include clock ticks *
- * - Converted some registers from ints to pairs for much cleaner code *
- * TLP (20-Jul-2002) Ver 1.10 *
- * - Fixed the dissasembly from the debugger *
- * - Changed all references from TMS320C10 to TMS32010 *
- * ASG (24-Sep-2002) Ver 1.20 *
- * - Fixed overflow handling *
- * - Simplified logic in a few locations *
- * TLP (22-Feb-2004) Ver 1.21 *
- * - Overflow for ADDH only affects upper 16bits (was modifying 32 bits) *
- * - Internal Data Memory map is assigned here now *
- * - Cycle counts for invalid opcodes 7F1E and 7F1F are now 0 *
- * RK (23-Nov-2006) Ver 1.22 *
- * - Fixed state of the Overflow Flag on reset *
- * - Fixed the SUBC instruction which was incorrectly zeroing the divisor *
- * TLP (13-Jul-2010) Ver 1.30 *
- * - LST instruction was incorrectly setting an Indirect Addressing *
- * feature when Direct Addressing mode was selected *
- * - Added TMS32015 and TMS32016 variants *
- * TLP (27-Jul-2010) Ver 1.31 *
- * - Corrected cycle timing for conditional branch instructions *
- * *
