11 / 78 page SM320VC5409EP FIXEDPOINT DIGITAL SIGNAL PROCESSOR SGUS046 − JULY 2003 11 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 on-chip ROM with bootloader (continued) Table 1. Standard On-Chip ROM Layout† ADDRESS RANGE DESCRIPTION 0x0000h − 0xBFFFh External program space 0xC000h − 0xF7FFh Reserved 0xF800h − 0xFBFFh Bootloader 0xFC00h − 0xFEFFh Reserved 0xFF00h − 0xFF7Fh Reserved† 0xFF80h − 0xFFFFh Interrupt vector table † In the ’VC5409 ROM, 128 words are reserved for factory device-testing purposes. Application code to be implemented in on-chip ROM must reserve these 128 words at addresses FF00h–FF7Fh in program space. on-chip RAM The ’5409 device contains 32K × 16-bit of on-chip dual-access RAM (DARAM). The DARAM is composed of four blocks of 8K words each. Each block in the DARAM can support two reads in one cycle, or a read and a write in one cycle. The DARAM is located in the address range 0080h−7FFFh in data space, and can be mapped into program/data space by setting the OVLY bit to one. |
