After OMAP3, go to OMAP4. This new generation of SoC also comes from Texas Instrument and is beginning to be integrated into devices such as RIM's playbook. The OMAP4 is an evolution of the OMAP3 with a new core for the CPU, a new GPU, a new video decoder and the same DSP as in OMAP3. So we have a Cortex A9, and a PowerVR SGX540 IVA3.
The password OMAP4 Cortex Cortex A8 to A9, with two cores, but a similar frequency: between 720 MHz and 1 GHz. The Cortex A9 is based on the ARMv7 instruction set and provides a short pipeline (8 stages) and management instructions OoO (Out of Order), which makes it more powerful than the Cortex A8 used in OMAP3.
Texas Instrument, unlike NVIDIA has integrated FPU (more efficient than in the Cortex A8) and the SIMD instruction set, used in particular for decoding some video. The core is physically a bit bigger, but faster in some cases. Texas Instruments has equipped its OMAP4 1MB of Level 2 cache, with a standard Cortex A9.
The C64x DSP society is always there to help the CPU to certain tasks. For the GPU is still a chip that is used Imagination Tech. In OMAP3 was a PowerVR SGX530. In OMAP4 is a PowerVR SGX540. the two chips are based on the same architecture, but SGX540 is faster: it increased from two to four units USSE and one to two rendering pipelines.
Power changes accordingly: 20 million triangles / s and 1 Gigapixel / s fillrate, against 14 million triangles / s and 500 megapixel OMAP3. IVA3 chip supports decoding of HD video and can decode H.264 1080p. For I / S, a big difference: the memory bus supports LPDDR2 and passes 2x32 bits, which saves bandwidth fairly consistent.
Also new, support for HDMI (1.3) while OMAP3 is limited to analog outputs. To the left is a classic full SoC. The OMAP4 is etched into 45 nm and two versions exist: the 4430 and 4440. The only difference is the frequency, the higher the version OMAP4440. The future is the OMAP5. Etched into 28 nm, SoC will turn Cortex A15, with two cores at 2 GHz, integrate two cores Cortex M4 for additional tasks and a PowerVR GPU SGX544 MPx.
