Items Specification
Cache memory 16-kbyte cache, mixed instruction/data
256 entries, 4-way set associative, 16-byte block length
Write-back, write-through, LRU replacement algorithm
1-stage write-back buffer
Maximum 2 ways of the cache can be locked
X/Y memory Three independent read/write ports
8-/16-/32-bit access from the CPU
Maximum two 16-bit accesses from the DSP
8-/16-/32-bit access from the DMAC
Total memory: 16-kbyte (XRAM: 8-kbyte, YRAM: 8-kbyte)
Interrupt controller
(INTC)
Nine external interrupt pins (NMI, IRQ7 to IRQ0)
On-chip peripheral interrupts: Priority level set for each module
Supports soft vector mode
User break controller
(UBC)
Addresses, data values, type of access, and data size can all be set
as break conditions
Supports a sequential break function
Two break channels
