Introduction

1.4.6Write Buffer

The SA-1100 has an eight-entry write buffer with each entry able to contain 1 to 16 bytes. A drain write buffer operation is supported.

1.4.7Read Buffer

The SA-1100 has a four-entry read buffer capable of loading 1, 4, or 8 words of data per entry. This facility permits software to preload data into the buffer for use at a later time without blocking the operation of the processor. Software can flush either a single entry or the entire buffer (four entries). The read buffer is controlled through system control coprocessor 15 and can be enabled for use in user mode.
