On-Chip Memory Descriptor Register
OCMPU | OCMEM Memory Protection Unit. This read-only field identifies a memory protected by an XRDC module. 0 (0): OCMEMn is not protected by an XRDC module. 1 (1): OCMEMn is protected by an XRDC module. |
OCMT | OCMEM Type. This field defines the type of the on-chip memory: 0 (000): OCMEMn is a system RAM. 1 (001): OCMEMn is a graphics RAM. 3 (011): OCMEMn is a ROM. |
RO | Read-Only 0 (0): Writes to the OCMDRn[11:0] are allowed 1 (1): Writes to the OCMDRn[11:0] are ignored |
OCMW | OCMEM datapath Width. This read-only field defines the width of the on-chip memory: 2 (010): OCMEMn 32-bits wide 3 (011): OCMEMn 64-bits wide |
OCMSZ | OCMEM Size 0 (0000): no OCMEMn 4 (0100): 4KB OCMEMn 5 (0101): 8KB OCMEMn 6 (0110): 16KB OCMEMn 7 (0111): 32KB OCMEMn 15 (1111): 8192KB OCMEMn |
OCMSZH | OCMEM Size “Hole” 0 (0): OCMEMn is a power-of-2 capacity. 1 (1): OCMEMn is not a power-of-2, with a capacity is 0.75 * OCMSZ. |
V | OCMEM Valid bit. This read-only field defines the validity (presence) of the on-chip memory 0 (0): OCMEMn is not present. 1 (1): OCMEMn is present. |
