Page 0 of L memory
Page 1 of L memory
The L memory is divided into two pages (pages 0 and 1).
The L memory is allocated in the addresses shown in table 9.1 in both the virtual address space
and the physical address space.
Each page has three independent read/write ports and is connected to each bus. The instruction
bus is used when L memory is accessed through instruction fetch. The operand bus is used
when L memory is accessed through operand access. The SuperHyway bus is used for L
memory access from the SuperHyway bus master module.
In the event of simultaneous accesses to the same page from different buses, the access
requests are processed according to priority. The priority order is: SuperHyway bus > operand
bus > instruction bus.
