Table 5–3. Video Port Peripheral Control Register (PCR) Field Descriptions

Bit	field†	symval†	Value	Description
31–3	Reserved			Reserved. The reserved bit location is always read as 0. A value
				written to this field has no effect.

2	PEREN			Peripheral enable bit.
		DISABLE	0	Video port is disabled. Port clock (VCLK1, VCLK2, STCLK) inputs
				are gated off to save power. DMA access to the video port is still
				acknowledged but indeterminate read data is returned and write
				data is discarded.
		ENABLE	1	Video port is enabled.

1	SOFT			Soft bit enable mode bit. This bit is used in conjunction with FREE
				bit to determine state of video port clock during emulation suspend.
				This bit has no effect if FREE = 1.
		STOP	0	The current field is completed upon emulation suspend. After
				completion, no new DMA events are generated. The port clocks
				and counters continue to run in order to maintain synchronization.
				No interrupts are generated. If the port is in display mode, video
				control signals continue to be output and the default data value is
				output during the active video window.
		COMP	1	Is not defined for this peripheral; the bit is hardwired to 0.

0	FREE			Free-running enable mode bit. This bit is used in conjunction with
				SOFT bit to determine state of video port during emulation suspend.
		SOFT	0	Free-running mode is disabled. During emulation suspend, SOFT
				bit determines operation of video port.

1Free-running mode is enabled. Video port ignores the emulation suspend signal and continues to function as normal.

TMS320C64x DSP specifications

The TMS320C64x DSP family from Texas Instruments represents a significant milestone in the realm of digital signal processing. Launched as part of the C6000 series, the C64x DSPs are designed for high-performance applications requiring intensive computational capabilities, such as telecommunications, audio processing, video processing, and industrial control systems.

One of the standout features of the TMS320C64x DSP is its VLIW (Very Long Instruction Word) architecture, which allows for an exceptionally high level of parallelism. This architecture enables multiple instructions to be executed simultaneously, boosting the overall throughput and allowing for complex data processing tasks to be completed more quickly than with conventional DSPs.

The C64x DSPs also boast an impressive clock frequency range, typically up to 1 GHz, delivering substantial computational power for real-time processing goals. Additionally, these processors feature extensive on-chip memory, including L1 and L2 cache, which significantly enhances data access speeds and helps reduce bottlenecks during high-demand processing tasks.

Another key characteristic of the TMS320C64x family is its support for advanced instruction sets optimized for specific applications. These include SIMD (Single Instruction, Multiple Data) capabilities, allowing for efficient handling of large datasets often involved in multimedia processing or complex signal manipulation.

For connectivity, these DSPs often integrate advanced interfaces such as EMIF (External Memory Interface) and McBSP (Multichannel Buffered Serial Port), facilitating seamless interaction with a variety of peripheral devices. This ensures that the DSP can suit different application needs and integrate well into various system architectures.

Texas Instruments emphasizes low power consumption with the C64x DSPs, making them ideal for portable or energy-sensitive applications. Advanced power management techniques and technologies, such as dynamic voltage and frequency scaling, are incorporated to further enhance energy efficiency without compromising performance.

In summary, the Texas Instruments TMS320C64x DSP family stands out due to its high-performance capabilities driven by a VLIW architecture, high clock speeds, extensive memory options, a rich instruction set, and advanced connectivity features, all while maintaining power efficiency. These characteristics make it an exceptional choice for developers looking to integrate robust digital signal processing into their applications, whether in telecommunications, audio and video processing, or embedded control systems.
