RE: Regarding TPU emulation

Sasanka,


Here is how I download and run my TPU code in emulation RAM (located at
0x0x302000).

////////////////////////////////////////////////////////////////////////

const BYTE acTPUROM [0x800] = {
#include "myTPUCodeInHex.ASC"
};

void
InitTPUDPTRAM()
{
	while (MPC555::TestBitW (MPC555::RAMBAR, 15))  ;

	if (not MPC555::TestBitW (MPC555::TPUMCR_A, 5))
	{
		const DWORD* pROM = (const DWORD*) acTPUROM;
		DWORD* pRAM = (DWORD*) 0x302000;
		forc (HBOUND (acTPUROM) / sizeof (DWORD))
			*pRAM++ = *pROM++;

		MPC555::SetBitW (MPC555::TPUMCR_A, 5);		// TPUMCR_A.EMU := 1
		MPC555::ResetBitW (MPC555::TPUMCR_A, 10);	// TPUMCR_A.TPU3 := 0
	}
}
