Performance Data

The tables below show UDP/TCP throughput in 100Mbps full-duplex mode with IMG2 running from Flash (XIP) and from PSRAM, at CPU frequencies of 240MHz and 320MHz. The XIP and PSRAM tests use different numbers of TX and RX descriptors.

Throughput running on XIP (4 TX / 4 RX descriptors) (Unit: Mbps)

CPU Frequency	UDP TX	UDP RX	TCP TX	TCP RX
240MHz	81.8	84.4	43.9	54.0
320MHz	81.3	84.2	44.5	54.6

Throughput running on PSRAM (8 TX / 8 RX descriptors) (Unit: Mbps)

CPU Frequency	UDP TX	UDP RX	TCP TX	TCP RX
240MHz	95.6	95.6	92.1	94.9
320MHz	95.6	95.6	94.4	94.9
