... Description The SA-110 is a general-purpose, 32-bit RISC microprocessor with a 16 Kbyte instruction cache (Icache Kbyte write-back data cache (Dcache); a write buffer; and a memory-management unit (MMU) combined in a single component. The five-stage pipeline distributes tasks evenly over time to remove bottlenecks, ensuring high throughput for the core logic. The SA-110 on-chip MMU supports a conventional two-level page-table structure, with a number of extensions ...

... SA-110 Microprocessor Write Buffer The SA-110 has an 8-entry write buffer with each entry able to contain 1 byte to 16 bytes. The write buffer can be enabled or disabled by software. The write buffer is further controlled by a bit in the MMU page tables; so the MMU must be enabled before the write buffer can be used. ...

... TLB supports only the flush-all function. Memory-management exceptions preserve the base address registers, eliminating the need for “fix-up” code. Cache The SA-110 has a 16 Kbyte, 32-way, set-associative Icache with 32-byte blocks and a 16 Kbyte, 32-way, set-associative, write-back Dcache with 32-byte blocks. Instruction Cache The Icache supports the flush-all-entry function, and the replacement algorithm is round-robin within a set ...
