Purpose
General
5.2.1 Flash memory bank
DMA
CPU
Master Port
The flash accelerator block in the LPC17xx allows maximization of the performance of the
Cortex-M3 processor when it is running code from flash memory, while also saving power.
The flash accelerator also provides speed and power improvements for data accesses to
the flash memory.
The flash accelerator is divided into several functional blocks:
Figure 13
In the following descriptions, the term “fetch” applies to an explicit flash read request from
the CPU. “Prefetch” is used to denote a flash read of instructions beyond the current
processor fetch address.
There is one bank of flash memory controlled by the LPC17xx flash accelerator.
Flash programming operations are not controlled by the flash accelerator, but are handled
as a separate function. A Boot ROM contains flash programming algorithms that may be
called as part of the application program, and a loader that may be run to allow
programming of the flash memory.
