Dual-Port TPU3 RAM (DPTRAM)
20.2
20.3
The DPTRAM module consists of two separately addressable sections. The first is a set of
memory-mapped control and status registers used for configuration (DPTMCR, RAMBAR, MISRH,
MISRL, MISCNT) and testing (DPTTCR) of the DPTRAM array. The second section is the array itself.
All DPTRAM module control and status registers are located in supervisor data space. User read or write
attempts will result in a bus error.
When the TPU3 is using the RAM array for microcode control storage, none of these control registers has
any effect on the operation of the RAM array.
All addresses within the 64-byte control block will respond when accessed properly. Unimplemented
addresses will return zeros for read accesses. Likewise, unimplemented bits within registers will return
zero when read and will not be affected by write operations.
