2ARM920T Core and Advanced High-Speed Bus (AHB)
2.1 Introduction
This chapter describes the ARM920T Core and the Advanced High-Speed Bus (AHB).
2.2 Overview: ARM920T Core
The ARM920T is a Harvard architecture core with separate 16 kbyte instruction and data
caches with an 8-word line length. The ARM Core utilizes a five-stage pipeline consisting of
fetch, decode, execute, data memory access, and write stages.
2.2.1 Features
Key features include:
ARM V4T (32-bit) and Thumb (16-bit compressed) instruction sets
32-bit Advanced Micro-Controller Bus Architecture (AMBA)
16 kbyte Instruction Cache with lockdown
16 kbyte Data Cache (programmable write-through or write-back) with lockdown
Write Buffer
MMU for Microsoft Windows CE and Linux operating systems
Translation Look-aside Buffers (TLB) with 64 Data and 64 Instruction Entries
Programmable Page Sizes of 64 kbyte, 4 kbyte, and 1 kbyte
Independent lockdown of TLB Entries
JTAG Interface for Debug Control
Co-processor Interface
