The data spaces can be considered either separate (for some DSP instruc- tions), or as one unified linear address range (for MCU instructions). The data spaces are accessed using two Address Generation Units (AGUs) and separate data paths. 3.2.1 DATA SPACE MEMORY MAP The data space memory is split into two blocks, X and Y data space. A key element of this architecture is that Y space is a subset of X space, and is fully contained within X space. In order to provide an apparent Linear Addressing space, X and Y spaces have contiguous addresses. When executing any instruction other than one of the MAC class of instructions, the X block consists of the 64 Kbyte data address space (including all Y addresses). When executing one of the MAC class of instructions, the X block consists of the 64 Kbyte data address space excluding the Y address block (for data reads only). In other words, all other instructions regard the entire data memory as one composite address space. The MAC class instructions extract the Y address space from data space and address it using EAs sourced from W10 and W11. The remaining X data space is addressed using W8 and W9. Both address spaces are concurrently accessed only with the MAC class instructions. A data space memory map is shown in Figure 3-6. Figure 3-7 shows a graphical summary of how X and Y data spaces are accessed for MCU and DSP instructions. 23 15 0 PSVPAG(1) 15 15 EA<15> = 0 EA<15> = 1 16 Data Space EA Data Space Program Space 8 15 23 0x0000 0x8000 0xFFFF 0x00 0x017FFE Data Read Upper half of Data Space is mapped into Program Space Note: PSVPAG is an 8-bit register, containing bits <22:15> of the program space address (i.e., it defines the page in program space to which the upper half of data space is being mapped). 0x001200 Address Concatenation BSET CORCON,#2 ; PSV bit set MOV #0x00, W0 ; Set PSVPAG register MOV W0, PSVPAG MOV 0x9200, W0 ; Access program memory location ; using a data space access 0x000100 |
